Coming Soon - Reeflux 20K

[Buganddoug]

What are more blue 12k or the 20k. I am not looking for a very blue tank.

[JRaquatics]

I would suggest the 12ks still the best overall color lamp IMO.

[tegee]

The 20k's definitely have more blue and I believe higher Par value. The colors do not look washed out with ReefLux 20's, but I am no lighting expert. I ran the ReefLux 12's for over two years with good results and switched to the 20's to see how I like them. I really like them and will continue to run them for 6-8 months.

[serpentman]

I am very glad to hear I am not going crazy. A buddy of mine came over and commented, "dude, no offense, but even though your colors look good, nothing is really popping like it used to". I've been running the 250W SE Reeflux 20Ks since June of this summer. However, I have been thinking for about 2 months now that the tank looked way too yellow and was even considering adding 2 more VHO actinics (running 4 now).

I took some PAR measurements tonight and its still very high (~400 mid level in the tank) so am reluctant to switch them out just yet due to the growth I get. However, I am not liking the way my tank is looking....

Considering Radiums but wondering how long they last before color shifting. Any ideas?

[Oldtimer]

I originally thought of going with 3x 250W 20K Radiums + 4x 60" T5's for my 240 SPS display. Since I seem to find the Reeflux 12K's to be pretty popular and readily available, I thought I would go with them instead (not liking what I'm hearing about the 20K Reeflux's). But, I'm now leaning towards the 20K Radiums again. Any input here? My thought was to go with 2 Aquablue+ and 2 Actinic+ T5's to supplement the MH's. Thoughts?

[dja1980]

It seems that the issues with the 20K's are primarily coming from DE bulbs? I'm going on 7 months with my 400w SE bulbs and the color is still going strong.

[Moebuis]

I've been running my 20k bulbs for about a week now and like them very much. The color is similar to Radiums and much brighter than the 12k bulbs that I tested. I changed from 10k XM bulbs and the coral colors look much more vibrant.

[serpentman]

It seems that the issues with the 20K's are primarily coming from DE bulbs? I'm going on 7 months with my 400w SE bulbs and the color is still going strong.

I am definitely having yellowing issues on my SE 250W bulbs which are 5mos old. I absolutely loved the color when I first got them. However, they shifted after about 3-4 mos. They still put out great par, but the corals do not "pop".

One is noticeably worse than the other two, even if I interchange ballasts.

[dja1980]

I think I read a few other posts about the 250 watters having problems as well. Has anyone had issues with the 400 SE bulbs, or are people primary having issues with the DE and 250w SE bulbs only?

I know on my step-dad's tank, we decided to go with the 12K again on the 250w SE bulbs because I thought I remembered reading issues about the 20K in the 250w SE. He really likes the look of my 400 watters though.

[tegee]

Serpentman,
What ballasts are you running. It has been 1-month now running the 250w 20k ReefLux on the CoralVue ballasts (non-dimmable) and the color is fantastic. I hope the color does not shift. They are definitely much brighter than the 12k's that I ran for 2+ years. The blue is much more noticeable too. Unfortunately I can not run Radiums because of my ballasts so I am going to stick with the ReefLux 20's and may supplement with VHO's.

No bro, this is a reeflux 250w se problem only. The 400w is an entirely different beast. No problems there what so ever....reeflux 20k 250w sucks.... It should be discontinued.... IMO

[naldopr]

if some one can post some photos of the 400 watt will be nice since I haven't see them personally

[henrystyle]

I saw a 400w 10k reeflux in person over a 400g tank and the color was so nice the owner told me he doesn't turn on his actinics anymore because of it. Said they were not needed...400w are real nice!

[daahles]

Hey guys, I'am working on a 65 gal build and wanted to get your opinion on lighting. I want to be able to grow LPS and maybe SPS in the future. The tank is 25" deep with a 2.5 to 3 inch sand bed. Looking at the CoralVue dimmable MH ballast. I am thinking 250 watts might not be enough so if I get the 400 watt and turn it down that would give me a lot of flexability. Am I on the right track? One other question, with the dimmable ballasts when you set them to the brightness you want does it stay there as the timer turns the light on and off or do you have to set it every time it turns on?

[mystery_reef]

anyone try the 150w reeflux 20k hqi?
any issues with these bulbs yet?
also, what is the cheapest place to get them? not that many online vendors carry these.
thanks!

thx. i just noticed that you guys do carry them. will be ordering soon!

[Rouselb]

I just had one of the Reeflux 250W SE 10k bulbs just turn blue all of a sudden. The PAR dropped to almost nothing. I sent it back to CV, and they are sending out a new bulb. Said it was a fluke. I like the PAR out of the 10k, but the corals really did pop more with the 12k.

I got these a month or so ago, They are awesome!!! I have them on sunpark(current) electronic ballasts. They are bright like a 10k but with a non-overwhelming blue that seems to make the corals glow. Still run my actinics for extra blue.

i have 4 pc's so plenty of actinic supplement. i will be running them on magnetic coralife ballasts. hopefully they will run nicely and last 12 months on these ballasts, anyone know?

Sorry for the delayed response. I am running them on Galaxy ballasts.

[Darth Reefer]

TIA.

The 400's I run had red stuff on them as do Radiums IIRC. It will go away as they burn in. Usually the break in period is around 100 hours or so.

[JeffCo]

Are there still issues with the 20K 250w DE turning yellow? Going to order soon and can't decide between the 12k or 20K. They will be used along with 2 400 watt radiums on a PFO HQI ballast.

[JRaquatics]

CoralVue supposedly fixed any issues associated with the Reeflux 20k. I will be throwing a new set over my tank to see what they are like. I still keep going back the the 12ks and they still seem to be my favorite bulb. I will keep you posted on the 20ks though.

[tegee]

Hello Jeremy,

What issues were associated with the 20k's? And when did they begin fixing them? I bought them back in October and been using them since. Should I have any concerns about having an order batch/lot #?

Thanks..........

[JRaquatics]

There wasn't really an issue. It was just that everyone wanted/expected a bluer bulb that closely resemble the Radium 20k. I for one was happy with the lamp but it was a little too blue for my liking. I am a Reeflux 12k fan, it to me looks more natural.

[naldopr]

the problem I see with this 20k is that they just don't pop red like radium
and in my case they get yellow after 4 months. when new they look good to the eye but honestly they just not pop color in my opinion.every time I go to my friends and see their tank with radium is a huge difference they look similar to the eyes crispy white but the corals look so nice and colorful. I wish they fix that problem I like reeflux bulb the price is reasonable and high PAR but I will use radium for now color are better but the price kills me.

[broke1]

I'm still interested in the 400w 20K. The thread has become very confusing as it's hard to make sense of the opinions on the bulbs as it's hard to tell which wattage of bulb people are using.

There was an issue with the 250w DE 20K, but no issues with the 400w SE 20k if I have read through this thread correctly.

Have I missed somewhere in the thread where the PAR numbers for the 400w SE were posted?

[RokleM]

To summarize my findings:

250 SE on a coralvue electronic (non adjustable) is less than spectacular. The color is pretty good with a nice blue, however PAR is relatively low. A Radium underdriven absolutely stomps this bulb in actinic punch and in PAR, and the results are almost just plain sad vs a properly driven radium. I've had two of these with the same result. One was probably from one of the very first batches, one from a much later batch (so likely not a "first batch" manufacturing issue, but true results).

400 SE have somewhat better results, however it's still a less than spectacular bulb. I've had seven (three orders of two at different times since they came out, plus one individual purchase). All were driven via CoralVue adjustable ballasts. Results are similar regardless of if they're driven to spec or overdriven, as well as varying nipple orientations. One cracked on me, without any water splash (along the side away from the water). One I killed via a splash, completely my fault (spooked my tang while doing maintenance). One died for no apparent reason and just stopped firing. The other four lasted for a period, but I ended up with less than six months of run time on them. The PAR right out of the box is great, and is slightly more blue with an actinic punch than the 12k. Right at that point, it's honestly one of the best bulbs I've used. However... the happiness you have will wear off soon. I would put the life expectancy of these bulbs at about 4 months driven 5-6 hours a day, even lower than extremely overdriven Radium 400w's (450 vs the 360 specification). At two months, there is already a drastic color swing, and at 5 months, they look VERY white and almost yellow, with a DRASTIC drop in PAR. Typically when you replace a bulb or put a new bulb side by side with an old one of the same type, there is a difference. Most of the time it's a bit brighter, maybe a little bit more blue or actinic punch. At 4-6 months, you can't even tell that the old bulb is the same brand or type as a new due to how drastic of a color swing and PAR difference there is.

No testing of DE's from me.

In my opinion, stick with the 12k's unless you have money to burn swapping them at 4 months. I honestly personally believe CoralVue should either just scrap this bulb in entirety, or pull them off the market and go back to the drawing board... But that's just me. Having tested probably 10-15 bulbs over the years on 250DE, 250SE, 400SE, I honestly think these are some of the worst bulbs made. I kept trying them due to the success I had with the 12k's. I've moved on and don't plan on buying any more of them.

Note: I saw Jeremy stated they "fixed the issues", so hopefully all my testing over the last year is null and void and they've come out with a product now that doesn't... well... suck :lol:

[broke1]

That was the detailed response I was hoping for. At this point I think it might be better to switch the ballst and just make the jump to Radiums. It's a shame as I have had great luck with the 400w 12Ks, just wanted a bluer bulb.

[RokleM]

Honestly with as horrible as luck as I had, IF you can wait... I'd see what Jeremy comes up with. However, there won't be 100% proven results for at least a few months of running.

[broke1]

I'm at that point where te bulb has to changed, I'm actually past that point. I have had weird algae growing in only this tank which is tied into four others, so I can only link it to the bulb being old. Not really important to this thread, but that's where I'm at.

Are you able to property drive a Radium with your CoralVue adjustable ballast? I've got the same ballast and have been running my 400w ReefLux SE 20Ks since May (NOT overdriven). Based on your info, I'm probably ready to swap them out.

I run mine for 8 hrs/day, and while color still looks fine, I would imagine that PAR has dropped off considerably. I've got new set of 20Ks standing by, but maybe I should consider looking at Radiums for the next go around?

[tegee]

RolkeM........I have used the 12k's for several years with good results and switched to the 20k's back in November with average results. My question is: I have CoralVue non-adjustable ballasts so can I "get away" with running Radiums with a 250w SE bulb setup? I really want to switch to Radiums but have always read and/or been told they need to be "over-driven" for good results.

And insight would be greatlyappreciated.......Thx

[JRaquatics]

I thought the 20k Reeflux had very decent par when I tested it on my lighting setup. 250w 20k Radiums will have low par and look very dim- very blue look if not over driven.

[broke1]

This is what has become very confusing about this thread, the 250w SE or DE and the 400w SE seem to be very different animals.

Has anyone tested the PAR of the 400w SE 20k?

[JRaquatics]

Yes. Darth Reefer has done par testing on the Reeflux 20k 400w.

Well, no adjustable ballast truly runs it any bulb to spec in my limited specification knowledge. If you're talking 250, you could hopefully get 250+10% (275, so it's getting close), but I personally haven't tested that.

Common misunderstanding. 250w SE are actually closest matched to an American "HQI ballast", so running them on a HQI ballast isn't actually "overdriving them", it's actually running them closest to how they should be. Many don't understand this and/or just consider running a 250w SE bulb on a HQI ballast as overdiven, which the Radium is not in this case (one of the only SE bulbs that is actually closest matched to "HQI ballast" spec). 400's on the other hand are actually a ~360w bulb and quite frankly are unimpressive at that wattage. Most people severely overdrive them on a HQI ballast at 425-460 which diminishes the life expectancy... All on purpose. That being said, they look AWESOME for the six month life they have. I ran these for a couple years this way.

I thought the 20k Reeflux had very decent par when I tested it on my lighting setup. 250w 20k Radiums will have low par and look very dim- very blue look if not over driven.

What ballast on the radium? If you're running them on a coralvue electronic, it's not actually running them anywhere near spec, more like 225-230 watts from the wall (minus whatever is lost on it's way to the bulb) in my testing. If that's the case, ye they will not look near as good as they should since they're only getting roughly 3/4 of the wattage they should. When driven properly, I can't register any PAR within 6 inches of the bulb, which means it's over 2000 PAR. That's as good as a Reeflux 400w at less than 3/4 of the watts.

... Sorry, didn't mean to sidetrack this thread by mentioning a Radium in my post, and if you guys have Radium questions (unless RS wants them posted here), feel free to PM me so this thread can get back to Reeflux 20k subject ;)

I probably won't try them again, but am honestly interested in how the "new" and hopefully fixed bulb ends up turning out.

[JRaquatics]

I don't mind anyone talking about other bulbs especially the Radium. Yes, I was overdriving them on a CV Dimmable ballast with short lead cords to the reflector. The par between the Radium over driven and the Reeflux 20k where very close. I do agree that the Radium is still not firing to the ideal wattage but I won't have to replace them every 4-6 months either. I received a new set of 20k Reeflux lamps today so I will see if I notice a difference tomorrow when the lights turn on.

is there a way I can see your tank with the 12k on? I haven't try them yet. my radiums are on the way but I could also use this to compare.
thanks

well I got my radium 2 days ago I got them at my lfs for $69.99 they are way smaller than the reeflux bulb, at first they where very blue now the seen to be getting more white with a hint of blue but let me tell you my corals look amazing my ora verde looks great with the reeflux it was brown and now is pure green base neon green polyps and pinkish tips my ora green birdnest look great to everything look great for now, I put one bulb to compare and definitely the reeflux where very yellow I will see if I can get a photos till now I'm very happy with the radium.

[agsansoo]

naldopr, which reeflux did you change out, 12K or 20K ?

[naldopr]

20k

[wfgworks]

So whats the latest with the 20k bulbs. I'm currently running the 400w 12k and the color is really nice. Are the 20k really blue?

[naldopr]

I think on the 400 the look very nice but mine in 250 nana lol

[tegee]

Don't buy the 20k's until they have all the kinks worked out imho. I have them and after 3+ months the blue is gone and they are beginning to bleach my sps corals. Was really happy with the 12k's and will most likely go back to them with some vho supplementation or try Radiums. The 20k's were/are are waste of money from my experience.

[skiformance]

any update on the gen 2 20k bulbs?

[tegee]

Do not know and wish we had clear direction from CoralVue on what's up with these bulbs. Just switched to XM 10k's with VHO supplementation after 3-years with ReefLux bulbs (12k's and 20k's most recently). It will take a lot for me to go back to a ReefLux bulb anytime soon. I do not mean to beat on a company, but the 20k's did me in.......only 2-3 months on a bulb and all the color was gone. Beat my sps's up with the color shifts and now that I am running XM's the past months things have improved.

IMHO......a very over-hyped bulb.

tegee, you have magetic ballast or electronic? ( ballast does make big difference)
I loved my 20k 400w on electronic ballast! as good a bulb a radium.
( I like the radium better in 250W )

[tegee]

I am running (3) 250w CoralVue electronic ballasts. Still trying to find the right MH/VHO combination to match the 400w Radium look. If I can not find that combination by the fall I am going to switch to 400w setup.....

Hello Charlie ---
I've just been reading through many of the posts on this thread. I need to purchase new 250w SE bulbs for my system and I can't make up my mind on which way to go. I'm currently running 3x250w Reeflux 12K bulbs on CV Dimmable Ballasts with 4x140VHO sup's. I'm wondering if I should replace my 12K's with Radiums. I see alot of people are raving about them. I have yet to find someone say, "Yes, these Radium bulbs are great and I'm very happy with my coral growth and color". What is your opinion?

if you have good growth and coloration stay with your set up radium are great the color is amazing but the price is killing me lol

Growth and coloration are good. Some of my Blue and Purple corals are fading. I hoping its because its time to change the bulbs.

I decided to try 2 Radiums and 1 Reeflux 12K. What is general life expectancy of the Radiums?

250w Radiums on a quality ballast (Lumatek/Icecap/etc) at either under spec (250w/electronic) or at spec (HQI)... 12 months is not unheard of at all. The coralvue non-adjustable ballast is terribad at running these bulbs.

400w'ers are a whole different ballgame. They're ~370w or so to actual spec, so even a normal 400w ballast might be overdriving them. They're a remarkably unimpressive bulb... UNTIL you abuse them on an HQI ballast. PAR and colors there are absolutely fantastic, but 6 months lifespan if you're lucky.

[dja1980]

Hmmm... I was also thinking about giving the Radiums a try. I'm currently running the 400w ReefLux 20K SE bulbs on CoralVue Dimmable ballasts with LumenBright Mini reflectors, and I think it might be too much PAR.

I haven't had any issues with the ReefLux 20Ks in terms of color shift. In fact, I REALLY like the brightness and color of these bulbs. However, I suspect that I'm having a problem with cooking corals. I was thinking that maybe switching to the 12Ks or Radiums might solve this.

[tegee]

dja1980.....
I had a terrible issue with the ReefLux 20k's. My sps's were definitely NOT happy. Switched to 10k XM's with mixed results. It has been a bear trying to find the right bulb for my 250w setup. I have non-dimmable 250w CoralVue ballasts, so I am definitely boxed into a corner until I can pony up some $$$ for new ballasts.

RokleM.....
GREAT info. What exact setup are you running? I can not make the jump to 400w, so 250w is all I can accommodate for several reasons. I have non-dimmable CoralVue ballast and need some definitive direction on ballast type and bulb selection. This has been by FAR the most frustrating part of the hobby. I can never seem to match bulb/ballast to get the color I am looking for.

Thanks both for your insight......

In 250w with electronic ballast, the best bulb I ever ran was the radium. My SPS frags really grew out and I like the color.
I really liked the 20k reeflux bulbs, in 400w. Did not like the 12k at all (weak)

I forgot , not only does ballast make big difference, so does reflectors.
You could say the lumenbrights are cooking the coral in 400w.. which one is to blame :) (both?) as said earlier finding the right combo is very hard for most.
We each see things slightly different.

BTW, my 250ballast were ARO brand. I never tried coralvue 250w, I heard bad things about the earlier verisions of coralvue ballast.
My 400w electronic were Coralvue adj. ran @1 yr and loved them!

Do you recall what bad things you heard about the earlier versions? The reason why I ask is because I think I have a set of the older version ballast. They look different than the newer version, but have not given me any problems. Would you suggest the Galaxy ballasts instead?

Reading here on RC. I remember people saying you get lower PAR (output) on many of the popular bulbs. Which could be true. ( I don't recall checking) you can check here-- http://www.manhattanreefs.com/lighting
Some said they did not last long, which I found to be highly questionable.. because I never found a person that actually had one go bad quickly. ( they were just carrying tales)

250w Radiums on a quality ballast (Lumatek/Icecap/etc) at either under spec (250w/electronic) or at spec (HQI)... 12 months is not unheard of at all. The coralvue non-adjustable ballast is terribad at running these bulbs.

400w'ers are a whole different ballgame. They're ~370w or so to actual spec, so even a normal 400w ballast might be overdriving them. They're a remarkably unimpressive bulb... UNTIL you abuse them on an HQI ballast. PAR and colors there are absolutely fantastic, but 6 months lifespan if you're lucky.

Would you consider Galaxy to be a quality ballast for running Radiums?

One thing I never tried was 400w radium on 250HQI ballast. I believe my 250HQI put out 340w ( was yrs ago, german bulb) .. I wonder if that would have been to low and would have dimmed it too much?
And what the 400w coralvue dimmable ( love them) does on 400w radium (370) ? ( I have both of these still, but no tanks at the moment)

[dja1980]

Not to get too off topic, but I e-mailed CoralVue this morning regarding ballasts for Radium bulbs. Here is the response I received:

Me...
Since Coral Vue is the “Master Distributer” for Radium bulbs, do you guys also make a ballast that will properly drive these bulbs?

It is my understanding that the 400w Radium runs best at wattage greater than 400w… is this correct?

I’m currently running 400w ReefLux SE 20K bulbs, but I think I’m getting too much PAR when combined with my LumenBright Mini reflectors.

CoralVue...
That is not correct, the 400 watt radium lamps are rated at 380 watts. Anything over 380 watts over drives and shortens the life span of the lamps as well as the color temperature.

We make a new dimmable ballast where you can select the wattage output to the lamp and this ballast will run the Radium 400 watt lamps where they are rated.

Me...
Thanks for the fast reply!

I actually have the older CoralVue Dimmable ballasts (gray knobs), so it sounds like these might work.

So, you would actually recommend dialing down the ballast to 380w to get the best color potential from these bulbs?

CoralVue...
If you want to get the most life and true color temperature of the Radium lamp that is what I recommend you do. Many people want to over drive these lamps and they are lucky to get 6 months of life out of them.

I wonder if this would ring true with a CoralVue 250w ballast running 250w Radium bulbs??? I would love to run Radiums if I knew it would be a slam dunk??? What do you think?

Thanks

I would be interested to know as well.

In the meantime, I contacted a rep at Sunlight Supply and he recommended the 250W Galaxy Select-A-Watt, part #902483. He said it was perfect for driving a 250W or 400W Radium bulb. I was sold. If anyone has an opinion about the Galaxy Ballasts please let me know.

Thanks

[naldopr]

for now I run mine in a non coralvue Dimmable ballasts so far so good the only thing I notice is a slow growth obviously will get galaxy or cv Dimmable ballasts later on

[tegee]

I have heard the same thing in regard to the new Galaxy Select-a-Watt. Heard that it is the next best thing since the M80 ballasts??? But would like to know what others say too. I am ready to swap out my non-dimmable CoralVue so need to help. I definitely want to stick with MH over T5's and need to stay with 250w setup. I really want the 400w Radium look.......

Thanks

[RokleM]

RokleM.....
GREAT info. What exact setup are you running? I can not make the jump to 400w, so 250w is all I can accommodate for several reasons. I have non-dimmable CoralVue ballast and need some definitive direction on ballast type and bulb selection. This has been by FAR the most frustrating part of the hobby. I can never seem to match bulb/ballast to get the color I am looking for.


I haven't seen a lot of bulbs that really burn well on the non-adjustable (I've had 3 of those ballasts). I would probably stick with the Reeflux 12k with that ballast, or IF the 20k's are fixed possibly give one a try. If your plans were to get a different ballast, that's another story ;) Personally I'm downsizing big time (twins take up more time that I wish to not spend on my tanks anymore)... so my current setup is a 250w Lumatek adjustable, 250w setting (makes it slightly more blue than HQI), LPS, Lumenmax Elite.

Some shots for a upcoming club swap on that setup. Not the best pictures, but gives you an idea (assuming your monitor is calibrated correctly) of the punch WITHOUT any actinics. This is my temporary poly holding tank as I broke down the old systems and am working on building the new setup.

I'm running 250W CoralVue Dimmable Ballasts with the Lumenarc Mini Reflectors. I hope this helps in using the Radium bulbs

Hard to tell. I would crank the adjustable up ALL the way to max. Even at that, it won't be pulling near enough watts to meet spec, but may look decent.

Would you consider Galaxy to be a quality ballast for running Radiums?

Thanks ---
Chris

I don't have any experience with the Galaxy's, but that and the Lumatek are both SLS branded items. They actually have a near identical adjustable ballast now. Logic would state that if the adjustable Lumatek is doing well, the adjustable Galaxy would likely be fine too.

Sound logic, but I don't know if anyone has tested it. Problem is that the 250w (HQI) Radium run to spec actually is more impressive than the 400 (~370), so I don't know if it would be worth the time, especially if you're underdriving the unimpressive 400w at spec even further. The coralvue dimmable would likely run the 400w pretty well, just remember the 400 watt looks best with lots of power but it decreases life. Decrease the wattage for closer to spec, more life, less impressive output/colors. Increase/overdrive wattage for the WOW factor, less life.

for now I run mine in a non coralvue Dimmable ballasts so far so good the only thing I notice is a slow growth obviously will get galaxy or cv Dimmable ballasts later on

:thumbsup: If you haven't seen the Radium on a better ballast than the coralvue non-adjustable... it doesn't look THAT bad. However once you see the bulb to it's full potential, there's no interest what so ever wasting the bulb on that ballast ;) Colors are off, PAR is low, etc.

Naldopr and Tegee ---

I'm seriously considering purchasing the Galaxy Ballasts. If either one of you would be interested, I will be selling my 250W CoralVue Dimmable Ballasts. I should be making my purchase in about 2 weeks. You both can have first dibs on my CoralVue's.

Yea, Yankkee26th.....I am considering the Galaxy Select-a-Watt as well. But I am tempted to purchase your dimmable CoralVue. How many do you have? LKM your direction and we can discuss then. Thx.

I am getting really frustrated trying to find a good bulb for my sps setup. IMHO it should not be this confusing and frankly do not have the $$$ to keep throwing at bulbs, etc. trying to find the right color. Why can;t we find the 400w Radium color in a 250w bulb/ballast setup........

I have 3 CoralVue Dimmable Ballasts wired up to 3 Mini Lumenbright Reflectors. I will know by May 24th which direction I'll be going in. I'm going to keep the reflectors but if I decide to go with the Galaxy's and sell the CoralVue's you'll be the first to know.

I ordered 2 250W Radium and 1 Reeflux 12K bulbs. I will be receiving them on Saturday. I can't wait to fire them up. Since the CoralVue's are adjustable, I'm going to start the bulbs off under half drive. Then gradually start to overdrive them over a months time. I'm going to play with the adjustments until I'm happy with the appearance of my corals. I'll let u know. I feel the same way you do. Their has got to be a way to make 250's work with the same results as 400's

Chris

[tegee]

Chris......sounds great. I CAN'T wait to see your results. I am running (3) XM 10k's with 250w CoralVue (non-dimmable) with LumenBrights as well. I like the XM's but waaaaay to much white. Liked the ReefLux 12k's when I ran them, but I was told but a lighting guru that they do put as much par (and other values) as well as the XM's. I ran the reefLux 20k's and literally were the worst bulb I ran with this ballast/reflector combo.

If I can not find the right ballast bulb combo I may be force to go to 400w Radiums. I have two TOTM winners in my area and both run 400w Radiums and swear by them. I may be tempted to try either the 15k or 20k XM's soon if my corals do not adjust to these 10k's. Been 8 weeks and my sps are not coloring up at all......growth is good, but I will sacrifice growth to get my color.

Please keep us posted......

Depends on your plans. I have no need to run 400's anymore, so I selected the 150/175/250/HQI model. If you plan to run 400's at some point and never 150 or 175, then yes the 250/HQI/400/HQI model is good. Neither are "ideal" or "wrong", it just depends on what your future might hold and attempting to remain flexible wit the hardware.

The 250w radium is pretty close to the 400w visually... a bit less par, but plenty more life (when both are driven high).

[tegee]

Thanks Eric........

So, from your experience, the new Galaxy select-a-watt with Radium 250w bulbs (driven high) will give me the 400w Radium look I am searching for? I need a slam dunk setup so I do not waste $$$ in the process switch bulbs, etc.

Thanks

[RokleM]

Your absolute best bet is to find someone in your local area that has a similar combo. What is "too blue" to some is "almost yellow" to others. What is "too bright" can be "way too weak". The only 100% way you'll be happy is if you see it in person and love it. That being said, I can't recall hardly anyone who's been unhappy with a 250 Radium on HQI.

[tegee]

Thanks RokleM......you are right. And the best setups I have seen are 400w Radium with traditional VHO T12 supplementation. So I need a slam dunk 250w setup. So it sounds like I need to upgrade the ballast to overdrive the 250w Radiums. I'll try to do some homework and see if that makes sense as you suggested???

My bulbs are due to be delivered tomorrow. I hope they get here before I have to go into work. Otherwise I'll be going crazy at the job wondering how my corals are going to look.

Unfortunately my tank isn't deep enough for a 400W system. So I'm going to have to stick with the 250's for now.

Yes, i'll keep you posted.

Although if I ever do I'm ready.

With all due respect, they either confused you, the person you talked to was confused, or their product works nothing like advertised on the site and the ballasts themselves. You disagreed then agreed with me in the same post ;)

Let me explain my logic. This is pertinent to both the Lumatek and Galaxy adjustable, unless there is something they aren't telling us.

Between the "low wattage" (commonly just referred to as 250) and the "high wattage" (commonly referred to as the 400), there are total of six possible settings.

150
175
250
250/HQI
400
400/HQI

The 250 is for your standard 250w SE bulbs. 250/HQI (just labeled HQI on the ballast) is for DE AND HQI rated SE bulbs (which is pretty much just the radium). Same with 400. 400 is SE 400's, 400/HQI for DE. Now again, 250 and 400w SE bulbs are often overdriven with the HQI setting (with the exception of the 250w radium which is actually a HQI rated bulb).

The 250w ballast (or low wattage) has the unique 150 and 175 setting.
The 400w ballast (or high wattage) has the unique 400 and 400/HQI settings.
However BOTH have 250 and 250/HQI.

Therefor EITHER ballast can run a Radium at 250 or 250/HQI (the right spec). So the only deciding factor is if you think you'll ever want the optional A) 150 and 175 or B) 400 and 400/HQI. You then pick which of the two makes sens.

Again, this is purely based on their product website, the info on the ballasts, and my and other's testing. If there is something different between the 250 and 250/HQI settings between the "250w" and "400w" ballasts they aren't telling us... then that's a whole other story and they're probably going to be in some deep water for false or deceptive advertising.

Follow?

Here's actually a link to a post of mine showing a video of 250 and 250/HQI testing on the Radium showing wattage and PAR between the two settings. I made this after some people were stating that the setting on the ballast didn't actually do anything (which clearly it does resulting in a 10-15% PAR increase as well as wattage).

[yankee26th]

Hey Eric ---

I'm sorry maybe I didn't explain myself correctly.

Yes, I agree. For Radiums use can use either ballast. According to some research I did their are those that say, to properly run a 250W Radium, it requires more than a nominal 250 watts. He recommended the #902483 because it has the capablitity for the need for higher wattage. What I forgot to tell you was that during my conversation with him I also mentioned that I might be going to 400's in the future. Thats probably why he also recommended the #902483.

By the way, nice video. Good Job. Do you know where I could by a Quantum meter, or similiar, without having to sell one of my kids.

Thanks

[RokleM]

:thumbsup: Yes they both have the capability for that higher wattage. But agreed, if you plan to go 400 that's absolutely the right path so you don't have to buy another ballast.

Our local club owns a PAR meter that's available to members. They are indeed not cheap.

[yankee26th]

Eric ---

How would explain the loss of color from corals?


There is definitely a big difference between the 250 and the HQI in your video.

Thanks ---
Chris

[RokleM]

In what regards? Many things can contribute to loss of colors in corals... lighting changes, parameter issues, etc.

[yankee26th]

To begin with I did notice my calcium level dropped off. It went from 480 to 340. I was dosing too much, then not enough. I reduced my dosing enough because I thought 480 was too high. So I reduced my dosing but forgot to take in consideration the load I put on my system by increasing the number of corals I have.
Secondly, I realized that I hadn't replaced my MH in over a year. Time passes by quickly when your not paying attention. Thus the reason why I ordered replacement bulbs. Thank God they'll be here tomorrow. I did recently add VHO to supplement my MH's, but they are only 4 months old.
Those are the only two differences I've noticed. Otherwise all my other parameters are the same.

Thanks

[tegee]

Good stuff guys.....will continue to run these 10k's until I can cough up the $$$ for the new ballasts. probably late summer at this point. But very good info and finally some straight forward discussing to get me to that 400w Radium look in a 250w setup.

Many thanks again......

Yes, it sounds like you had a number of issues. If your calc had that dramatic of a change, that means your alk was probably in about the worst state it can be swing wise. Add old bulbs to the stability issues, and yeah the corals are not going to be doing super well.

That being said, you said they're just bleached or lighter which is a good sign because they're still alive. When you get the new bulbs, I'd high recommend starting them off very high or covering the tank in numerous layers of screen to block some of the PAR.

So I guess this means you won't be interested in my CoralVue Dimmable ballasts?

[tegee]

No, no, no, I may be still interested but I need to do some homework so I have a clear idea what bulb/ballast combo will work. I am hoping to pick up some XM15's or 20k's or maybe even try an Ushio??? I am in the same boat as you right now. I really like CoralVue ballasts so that is still an option. We will definitely keep trying to see what works....

Hello Eric ---

Do you have the model # for that particular Quantum Meter that you used in the video? I'd like to see if I can purchase one.

Thanks ---
Chris

[RokleM]

It's the older model that's not available anymore. They have a new one out. http://www.apogee-inst.com/ Occasionally there are buys here as well as some of the reef vendors/sponsors who carry them. It's a high dollar item, so not overly common. They pop up in the used forum occasionally.

I was able to find the older model that you were using "NEW" for $269.00. It has a built in sensor located at the top of the unit. The best price on the new model I found "NEW" for $349.00. Whats your opinion on Milwaukees version? The cost on that model is $180.00.

I just installed both Radiums and the Reeflux 12k. I do notice a little difference. It doesn't seem quite as bright. Maybe my corals will. I have the ballasts set at 3/4 drive. I would like to get a light meter to check the difference in PAR between the bulbs. I'll keep you posted.

You wouldn't happen to have a kill-a-watt would you? Granted it doesn't measure 100% actuate as we don't know how much power is loss between the plug and bulb, but it's an idea. I hope the adjustable are better than the normal electronic, becuase I'm lucky to get 220-230w out of it. I am actually running normal electric with a radium on my rock tank right now (curing live rock), and it doesn't look near as good... but again just my personal impression.

If it was me, I'd crank the wattage up to full on the radium, and even at that it's unlikely that you're even close to it's full potential.

[tegee]

Thanks Eric and Chris for the updates and good luck on your findings......please report on what you find.

Eric & Tegee ---

No I don't have a Kill-a-watt, but I've been wanting to get one. I guess this would be a good excuse to buy one now.

I will take your advice and crank up the wattage to see what I get. Once I get the kill-a-watt I'll take some readings and inform you both of the results.

As I mentioned earlier, I still want to get the Galaxy ballasts. Once I get them up and running I'll take readings and compare. I'll keep you both informed.

Hey Eric ---

I just wanted to pass some information along to you.

I purchased a Kill-A-Watt meter and plugged in my CoralVue Dimmable ballasts. I turned up the wattage completely and got 255 Watts from the Ballasts.

Just thought you might want to know what the Dimmables would max out at.

I think I am going to have to buy the Galaxy's to take full advantage of the Radium bulbs.

I wonder what my 400w CoralVue Dimmable would max out at. According to CoralVue's website, the dimmable option gives you: "35% Dimmable / 2+10% overdrive".

Chris,

Please refresh me.....how many watts do the Galaxy's put out at the higher setting?

The Watt meter costs only $25.00 at Home Depot. Plug your ballast into it and take a reading on the watts that your ballast produces.

The particular model Galaxy I'm going to purchase is a Select-A-Watt 250/250HQI/400/400HQI. I think I recall the rep at Sunlight Supply said, using the 250HQI feature will produce 370 watts. Which is actually more appropriate for a 250W Radium bulb

That is what I thought. Please keep us posted and I still may purchase your CoralVue dimmables.

Thanks

I'll definitely need to sell them to help offset the cost of the Galaxy's

Hey Tony ---

Just wanted to update you on the addition of the Radium bulbs.

My lighting set-up started with 3-250W Reeflux 12K bulbs and 4-VHO's
(2-454's, 1-Actinic and 1-Super Actinic). The appearance was too bright white. Since I've added the 2-Radiums along with 1-Reeflux 12K, keeping the VHO's, the appearance is AWESOME! The Radiums are settling in and I still haven't added the Galaxy Ballasts yet. I placed my order for the Galaxy Ballasts through a LFS. He said he would match the price, of a Seller I found on Ebay, who I originally was going to purchase them from.

If you want, this is my email address - basbal@bellsouth.net. Drop me an email and I will reply with some pics of my set-up and FTS's.

Also, let me know if your still interested in my CoralVue Dimmable Ballasts before I put them on the "Selling" forum.

Keep in Touch ---

I must say I am very happy with the last set of Reeflux 20ks, in fact more so than I realized. One of the 20ks I was running was blown out this past week due to a splash incident and was replaced by a 12k. Needless to say I now prefer the 20k reeflux over the 12k because it does appear brighter and has a more concentrated blue hue than the 12k reeflux. Thus far they have also kept there spectrum.

[crsaz]

for those of you who have run both radiums and reeflux 20k's how did they compare(stricly color as I am not concerned about par) I have been considering making the switch to reeflux 20k's

[tegee]

IMHO...I do not think any bulb can compare to a Radium run to spec. Just my opinion. I ran the 20k's on a CoralVue and it was just ok color and coral performance. I ran the 12k's for three years and liked those much better.

Have CoralVue improved the 20k since it came out???

HTH

[naldopr]

crsaz in my case the radium did pop color in my corals that I can't get with the reeflux 20k green reds looks crazy on my radiums blues look ok a few sps got brown but recovering again but was my mistake this bulb are strong, in my opinion I like this better than reeflux the only down side is the price. but make me happy lol I wish this rf 20k have the same effect as radiums I use 10k in the past and love them but now for 20k I defently recommend the radiums.

I'm currently using 2 Radiums and 1 Reeflux 12K bulbs and I love the color in my corals. They look more natural and vibrant. I think once I purchase the Galaxy Selectable ballast the colors will come out even more. My CoralVue dimmables just don't provide enough wattage (255W max.) to drive the Radiums.

You mentioned about a few of your corals browning out. Before I changed to my Radiums, I have one acro that was a deep dark purple when I purchased it from a LFS. It has sinced turned, not brown, but more lavender under my old worn-out bulbs. Do you think that in time it will purple up again. Or is their something more to it. Please let me know.

[naldopr]

it will just give it the time. do you have photo of your set up

[yankee26th]

Yes I do. If you give me your email address I can send them to you. I really dont know how to send photos to RC threads.

I'll send you pics of my tank as well as all my equipment set-ups.

Any updates with how the Reeflux 20k bulbs are working for everyone?

[dja1980]

I just had another SE 400w stop firing after 3.5 months... my 2nd of 4. I contacted Coralvue, and they are going to send me a replacement... I requested a 12K this time.

[JRaquatics]

I have been running the Reeflux 20ks for about 8.5-9 months and still looking good. I usually replace my lamps at about 8 months but I have not seen the need to yet.

[wfgworks]

Do the new 20k bulbs have alot more Blue than the 12ks?

I dont know if I'm seeing things, but somedays my 12ks look more white and other days the tank seems more blue. Could this be a sign the bulbs are shifting?

[JRaquatics]

It is possible that they are getting old. It also could be the current being fed from the ballast is running the lamp differently upon firing. The 20ks are slightly richer blue than the 12ks. I like the look of them being overdriven slightly.

[schoolisbad1]

anyone have further information if they still color shift 6 months in or so? Any suggestions, im running a 250w icecap electronic ballast, radium was too blue.

We haven't seen any color shift problems in a long while... I would try the Reeflux 20K's again. Your Ice Cap ballasts will not drive a Radium hard enough to get the color spectrum you are looking for.

[schoolisbad1]

Alright thanks. The 20k reeflux sounds like what i'm looking for. I just don't want it to be underdriven/too blue like the radium was. - on the IC e-ballast.

[bagz727]

hmmm!

[cagri]

I just put on a new set 400 watt 20K and noticed that they are much bluer than they used to be. Have they been modified/changed? Now they are like radiums on electronic.
