Coming Soon - Reeflux 20K

[JRaquatics]

Due to popular demand CoralVue is finally coming out with a 20k REEFLUX bulb. This bulb will join the ranks of great Reeflux bulbs like the 10k and very popular 12k. Mike and I will be trying out the new 20K Reeflux in both 250w and 400w. Once we receive the bulbs from CV and burn in we will post some pick here along with our opinions on these new 20k bulbs.

Till then here is some specs provided by CoralVue.

bah,

you need to let someone who has run Radiums and Helios give their analysis. :p

[upsetter]

anxiously awaiting :)

[JRaquatics]

I received the NEW Reeflux 20k 250w bulb last night. I fired it up this morning outside of my normal photo period. I am quite impressed at this point, a 20k bulb that doesn't make the corals look hazy and the tank look dim. These new Reeflux 20k seem to really pack a punch. At first glance it looks like a Reeflux 12k with actinic supplementation. I will see how it burns in. I am going to try to get a par reading when it burns in for those interested in its specs.

First look at the Reeflux 20k

SOOOOOOOOOOOOOO JEALOUS !!!!!!!!!!!!:rollface: !!!!!!!!:rollface: !!!!!!!

[Tbduval]

JR,
An idea when these are going to be available? I would be very interest in trying these out as I dont want to put actinic supplementation on my tank. I currently run the 250 12k's on IC but want a little more blue. Thanks!

[JRaquatics]

Last I heard they were going to be available at the end of the month. If not then I would assume they will be available early January.

[victor90]

Cool I can't wait

[ostrow]

Wonder how these will look on my HQI ballasts. The 12Ks are about as white as any bulb-ballast combo I've ever seen. If the 20Ks would give what my current setup with VHO actinics give combined, I could save the money on the VHO use, which would be nice.

[bored4long]

will these be available in DE?

Yes, there will be a 20K DE as well.

[deeznuts]

I'm dying to know how they look...

Any more pics?

Did you notice any diffrence in color from yesterday's fire up?

Thanks!

[JRaquatics]

I will get more pics this weekend. Remember that the bulb is not burned in yet. I did notice a pretty huge difference in brightness and color between my 7 month old Reeflux 12ks and the new Reeflux 20k. The 20k was very bright and the colors sure did pop. I will place in new 12ks this weekend and see if I still notice a difference in brightness.

Your aquarium is just stunning JR. :eek1:

How did you cement all those SPS in such a natural looking way?
I tried to cement some corals last night with Aquamend and it was a nighrmare :rolleye1:

Also please let me know how long do you keep your MH on and what do you do for algae control as you seem to have NONE.

Thanks!

[JRaquatics]

Thanks for the compliments.
I start out with frags and glue them with cyanoacrylate gel. Works great, easy and really holds. It also doesn't make you skimmer go nuts.

Here is a link of what I use to glue my frags:
http://www.reefspecialty.com/Maintenance-Coral-Glue/c15_67/p132/IC-GEL-Insta-Cure-Cyanoacrelate/product_info.html

I run my light for 7-8 hours depending on the time of the year. Tangs and a large skimmer is my algae control. Don't be fooled though I do get spots here and there every now and then. It is just the life of a reef tank.

Do you glue them inside your tank beacuse thats the only way I can glue mine - there is NO way I can get my rockwork out for gluing...

Do you recommend this product for gluing inside my tank?

[JRaquatics]

Yes, you can glue it underwater. I mount all my frags underwater. The gel is really thick and doesn't float away. It gets activated by water so you do have a short span of time to get it where you want and mount it.

20k Reeflux
http://i372.photobucket.com/albums/oo164/reefspecialty/DSCN3443.jpg

If this is the true colors with the bulbs, then the 12k looks much better IMO.

[JRaquatics]

I really had a tough time taking top down shots because of the brightness of the bulb and my camera lens. The 20k has the same crispness and brightness (possibly even brighter than the 12ks)as the 12k just bluer.

FWIW the tank is lit with all new bulbs. The two side lights are brand new Reeflux 12ks and the center is the Reeflux 20. Right now the tank is shown in an un-normal state. All bulbs need to burn in as the 12k burn in whiter than they appear now.

[BreadmanMike]

I'll have to come over and steal frags... I mean look at it in person.

It definitely bluer, but at this point it is not a night and day difference. What I have noticed is more of my corals show their florescence under the 12k, so I am seeing more color in the greens and blues. Oddly enough I don't see that much of a loss of colors in the yellow and reds like I would have thought. But at this point it is still too soon to tell as the bulb is still burning in.

But I am really liking what I see at this point.:)

[Tbduval]

Thanks. The pictures look very close to the same color as far as the bulbs. Now I am interested the in the par on them! Thanks again!

They do appear very close because the 20k is as bright or brighter than the 12ks at this point. But there is a noticeable difference in the colors of the corals under the 20k bulb as compared to the 12k. Is it a huge difference, not really, as it looks just like the 12ks with actinic lighting supplementation.

Far as I know they are produced by the same plant that the Reeflux 10 and 12k are.

Any updates yet on the 20k? Thought u might be getting close to the 100 hour mark--- can u tell I'm past due for new bulbs? :)

[JRaquatics]

I am going to let the bulb burn in until the weekend. I have a feeling I may be over-driving it a bit, as it seems to be more like a 14-15k at this time. I have noticed my pink birdsnest brighten up to a stronger pink coloration and my blue table seems to glow. It is still seams as bright as the 12ks so I am really interested in the par numbers on these which I should have within the next couple of weeks.

[tweetyfish]

Why do you say you may be over-driving the bulbs? I was thinking of using these on HQI ballast.
Thanks

I have an dimmable ballast that can over drive a bulb 10%. Reeflux bulbs are not recommended to be over driven as it shortens the life of the bulb and the color accuracy.

This is taken right off of CoralVues' website
"Using HPS (High Pressure Sodium) or HQI magnetic ballast damages metal halide lamps. We do not warranty bulbs that are used with these ballasts. Metal halide bulbs being using on these improper ballasts run the risk of premature bulb life, explosion, improper color spectrum and excessively high ultraviolet radiation that could cause possible damage or death to fragile aquatic livestock. Anyone using our lamps with the above mentioned ballasts do so at their own risk, and we are not liable for bulb life or damage to aquatic livestock."

[tweetyfish]

Wow. thanks for the info. Do you think they would do ok using my icecap eballast?

Thanks

Those ballasts are the recommended ones for the DE 20ks.

BTW for those interested, we will have the 20ks in stock next week.:)

[Tbduval]

JR,
If you were to turn down your ballast to say, 100% instead of a 110%, does the bulb have more blue? Also, very curious on the par reading, because I need new bulbs and am waiting. I am trying to decide on the 12k's or 20k's. Are they going to be the same price as the reeflux bulbs now? Thanks!

I haven't had a chance to see how high I have them set. I will check and report back later tonight. It will be another week or so till I can get par reading on this bulb. The 20k Reeflux will be $5 more than the 10k and 12ks.

I checked my ballast last night and I was running it a little harder at 260 watts. I took it down to 250 and it did blue up a tad. It still appears to be a very bright 20k bulb. I still feel it looks like the 12k reeflux with actinic supplementation. I am anctious to see what par numbers come from these bulbs, because if they are the same or higher than the 12k reeflux, I found me a new bulb to run.:D

I am with you on that. I like the look of my reeflux 12k's but I always wanted a little more blue. I never used actinic supplementation because I didn't want to consume extra electricity. So if the par numbers are around the 12k's, I will put in an order for 3 bulbs!!!! Thanks JR!

How are you feeling about the CoralVue ballast + Radium combo?
Thinking of doing the same thing before I heard about the Reeflux 20k bulb.

I heard the Radiums dont proform well with an E ballast.

Thanks!

[BreadmanMike]

Remember the 400w Radium is actually 360w bulb. With the dimmables you can take the ballast down to 360w and drive the bulb properly. Of course you sacrifice par when you dive them at 360w. I can't wait to get the 20k Reeflux though. :D

I think they look great together, but I like the look of a blue tank.

Here is a interesting and great write-up about the possible benefits of 20k spectrum bulbs.

http://www.advancedaquarist.com/2008/12/aafeature1

[Obi-dad]

I saw that, seems to fly in the face of the often repeated 'lower K bulbs grow corals faster than higher K bulbs' that we see here on RC all the time.

[BreadmanMike]

Well the ballast and reflector came, but no bulb yet. My buddy is coming with his par meter Sunday, so hopefully it will be here by then. :)

[BreadmanMike]

Bulb came early this morning. I installed it, which I found a pretty easy way to do on the finished LB's. Instead of removing the glass I removed the socket instead with the two wing nuts. Much easier. :)

http://i32.photobucket.com/albums/d11/aquaticman74/IMG_1246.jpg

I tried to take pics of the bulb side by side, but I can't get my camera to take the correct color picture. It doesn't show any difference in the color from one side of the tank to the other and setting the WB doesn't help. I need someone camera literate to set my camera up for me one day. :)

Anyways, the 400w 20K Reeflux is much brighter then the 400w Radium. To me the Reeflux looks like the Radium when I used to over drive them on an SLS HQI ballast. It's almost a crisp white with a hint of blue. If the bulb stays like this after it burns in and the numbers are decent; I found myself a new bulb to run for sure. I have the bulb nipple down which is how I run the Radiums.

[JRaquatics]

Breadman, just so that you know CV recommends that the Reeflux bulbs be used with the nipple facing upward. I run my Reeflux with the nipple facing upward.

Off of CoralVue's site:
"It is important that SE mogul base lamps are positioned in the correct burn position. Please refer to the drawing and notice the small glass nipple in the center arc tube of the lamp. It is critical, for the correct color temperature to be obtained, that this nipple be positioned in the 12pm location when screwed into the E40 mogul socket. To help align this position you may have to pull the center tab in the mogul socket out to gain some length where the lamps base makes contact with the center metal tab. Make sure that once positioned in the correct angle that the bulb is snug and stable in the socket."

No I haven't. It is not recommended by the manufacture to run them on HQI ballast but I have been looking for someone locally I could bring the bulb over and see what it is like on an HQI. My guess would be a very crisp whiter look and possible shorter life span. I can overdrive the bulb 30% with my ballasts and do notice it look very crisp white/blue.

[ostrow]

I run the 250 watt 12Ks on HQI. They are absolutely white with no blue at all. I need VHO supplement. I was hoping the 20Ks would be enough blue that I could ditch the supplement.

Shoot me an email. Easy to arrange next week if you have time (not sure where you guys are though).

Overdriving the bulb 30% with your ballast will be just like running it on an HQI ballast. An HQI ballast will run somewhere around 330w using a kill-a-watt.

I am still really liking the look and so far the growth is just as good as when the 12ks were over the pillar. I will be the first to admit that I am not a fan of 20k bulbs. I have seen numerous one over friends tanks and they just look too dark to me. I prefer more of a 10k or bright white look with an actinic pop. This is why I am such a huge fan of the 12k reeflux, I get all the color and growth I want but have the brightness I prefer. Now with the new Reeflux 20k seems just as bright as my 12k so I am really happy. If the par is there I am for sure going to try 20k for a while.

[aurora]

My Reeflux 12K bulb needed replacing so I just switched to new Reeflux 20K's. I think the 20K appear just as bright as the 12K but with a bit more blue. The green does appears greener and the blue just as blue. I started this hobby with Radium for several years and would compare this bulb to more of a 15K bulb. It's definitely less blue than a non-overdriven Radium and a little less than Radium on overdrive. The problem I had with Radium besides the fact that it needs replacing every 6 months is that the blues looks more like purple and it was hard to differentiate between different shades of purple and blues. However, my Orange caps looks redder under Radium and more orange under Reeflux. The point is I think reeflux produce a more accurate color appearance of all the bulbs I've used. The Reeflux 20K appears to maintain this color accuracy despite being a bit bluer. My bulbs are still burning in and may look different in a couple of weeks but right now, I like the look.

I have been running one 20k reeflux since December 11 of last year. I actually think I have a slight advance in growth with the 20k over the 12k. This is why I am really interested to see the par differences between the two.

You already get crazy growth under the 12k's....... sounds you will be selling frags in the near future too!:D Your 20k's are nice in burnt in, so it should so the true par value of these bulbs. I hope they are at least what the 12k's are!

Can't wait to hear the par readings on the 20K!! I'm up for a bulb change and this 20K might be perfect switch from the 12K Reeflux which I run VHO supers with also.

Everyone is talking about overdriving the Reeflux bulbs and I'm using a Coralvue dimmable ballast. Does that mean I'm not supposed to run the bulb at full power?

If you have the ballast turned past where it clicks then you are overdriving your bulbs.

Jeremy is next, he'll be testing the 250 watt versions, I assuming(hoping) a side by side in every flavor :smokin:

So the bulbs are 14 inches from the surface? Radiums are supposed to be rated for 360 watts.

The ballasts didn't seem to adjust wattage when I turnned them down. I'm not 100% sure why that happened, but I didn't have time to mess with it. I had to get my other pendant hung up.

I like the 20K Reeflux better. It is so much brighter and I like the way the corals look under it better. I'll definitely be switching once the Radiums need to be changed out. Awesome bulb!

Well, yes technically if you were running them at 400 and it's a 360-380w bulb. The most common setup (and phenomenal par/color) is at HQI wattage ~425-450.

I actually run my 400w SE Reeflux 12k's on an HQI BW7, but will likely be bugging Mike and crew for 2x 400w Coralvue adjustable pending how this par test comes out.

[BreadmanMike]

I'm pretty sure Mike already tested the 400w 12k's on dimmable ballasts.

How old is the Radium? You're might be comparing an old Radium against a brandnew Reflex 20k.

[BreadmanMike]

The Radium has around 210 hours on it. Why would I waste my time testing an old bulb? ;)

[xinumaster]

Cool.

Jeremy,

Is Jim running 400w 12k's? Is that pic with any supplemental lighting?

[JRaquatics]

Jim was running 12k 400w Reeflux in that picture. Since then he switched to 3 lb minis with 12k Reeflux 250 watters. No supplemental lighting.

[reefdude135]

Has anyone run the Reeflux 20k bulbs on a magnetic ballast? Just wondering if it provides the same level of performance as with an electronic ballast.

[gliebig]

I just got my 400wt Reefux 20k's yesterday. Maybe they just need some burn-in time, but they look identical in color sidexside with my 400wt Reeflux 12k's. Couldn't tell a difference. I was really hoping for a lot more blue.

That was my first impression at first too. Are you using dimmable CV ballast? If you over drive them they will appear close to the Reeflux 12k.

I do not have the dimmable ballasts. Oh well, I guess I just have replacement bulbs for when my 12k's need changing. Kinda disappointed. Would radiums work on my ballasts? If so, would they be bluer?

Maybe I should ask it this way... What 20k bulb would actually look 20k on my ballasts?

You mean dark and blue. These bulbs were designed to be bright but have the spectral points high in the right areas. These bulbs do not look like your standard 20k bulb. To me they look like the Reeflux 12k with actinics running.

Radiums and XMs should work fine on the ballast but won't appear as bright.

[BreadmanMike]

I can tell you that the Radiums are bluer and a lot dimmer then the 20k Reeflux.

The 20k Reeflux is in the back left corner and Radiums are in the back right corner and in the front. Colors are off slightly, but you can see how much brighter the Reeflux is.

[BreadmanMike]

As soon as the Radiums are dead I'll be switching to the Reeflux. I'd switch now, but I promised my wife I would use the Radiums since I just bought them.

I've been thinking about putting the Reeflux in front so I can see it better from my chair.

Nope, it's an encrusting gorgonian. It's a friggen nightmare pest too. It's everywhere.

That sucks. Do you have any plans for eradication?

[BreadmanMike]

It doesn't like a lot of light as you can tell by where it grows. I figure with the new lighting it will only be in a few spots and I'll just live with it. I've been living with it for over a year now, so I'm used to looking at it.

I thought it was hydroids as well, but Inland Aquatics and Rod told me it was a gorgonian.

I'm pretty sure everyone is talking about the 20K single ended bulb, not a double ended.

Jeremy, just put in the 250 watt 20k last night. It was only for the last 2 hours of my usual 6. Very dim & blue (using coralvue ballasts- not dimmable)--- wondering if yours were like this for the initial burn in. Like I said, they were only on for 2 hours, & I've been running the Reeflux 10k for the last year, so I'm use to the nice punch of 10k-- but these look weak & washed out. Think I'm just panicking since I know I'm stuck with these for at least 6 mos. I'll wait a couple weeks for complete burn in & post some pics to show the difference for those interested.

This is interesting,could you post a picture?

I also have the non dimmable ballasts and I was wondering how they would burn under those...

[upsetter]

Lights don't come on until later today. I'll see if I can then. Like I said I'm trying not to be bummed about it. But these sounded very promising & I was very excited to light 'em up. I know there's a burn in of around 100 hrs usually for bulbs, but I thought they usually started off extra bright in the beginning, no matter what the Kelvin & then simmered down. Hopefully these will go the other way & brighten up. Again, I am coming from 10k Reeflux ... was sorta hoping for the Radium on hqi look though. We'll see, patience upsetter, patience.

[BreadmanMike]

upsetter, is the nipple up? My 400 is very close to Radiums on an HQI ballast.

[Medicine Man]

How do you adjust the mogul on a lumenarc SE reflector (full sized) so that the nipple is up?

[BreadmanMike]

You don't adjust the mogul, you just turn the bulb till the nipple faces up. If you have to leave the bulb a little loose in the socket and it won't fire, pull the little tab inside the socket out a little bit so it makes connection with the bulb. Make sure you unplug the ballast of course first. :p

[colubrid]

On my 400w Galaxy and 400W Bluewave HQI ballast the Reeflux 20K (new) appear more white in color than the Reeflux 12K (4 months old). In both cases I have the nipple oriented up. Do these bulbs burn in more blue or are they more white than the 12K Reeflux?

[upsetter]

Nipple is up at 12 oclock. Part of the blueness is that I'm running 4 54wt t5 blue plus--- which obviously are super blue. So I shut those off and the bulb looked much better. Still a little blue for me, but looked like a normal 20k I think. I'm going to try a couple figi purples that I just bought and see what that looks like & next I'll prob buy a couple of aquasuns and see how that looks. Could also try pointing the bulbs in the 3 or 6 oclock position & see what that does. I'll figure something out :)

[BreadmanMike]

upsetter,
Why not just have the T5's go off when the halides come on and then turn back on when the halides go off?

colubrid,
I'm betting when the 20k burns in it won't look as white as it does.

Hopefully everyone running them on all these different ballasts will chime in again on how they look after they are burned in. :)

All bulbs 12k to 20k will see "not as bright" as a 10k no matter what brand and ballast combo. There is a difference in brightness between the 10k and 20k reeflux and even with the 12k. I placed a Reeflux 10k over my tank the other night and it was indeed brighter due to the warmer light that we associate with brightness. Believe me when I tell you these 20ks are the brightest 20ks I have seen yet that are not over driven. To this day they have the impact in blue like a 20k but the punch of a 12k, giving the appearance of a 15k bulb. From what I have heard from other customers is that the Reeflux 20k looks like an overdriven 20k Radium.

[N-A-S-O]

Are there any numbers on the 250w yet?

[stanlalee]

I thought the whole concept of reeflux bulbs were good PAR without the yellow (and performance of a 10k with a touch of blue for the 12k). given that a 20k reeflux is kind of an oxymoron. they should just call the reeflux 12k the reeflux 15k which most people feel is a more realistic representation of the kelvin anyway and have Reeflux 10k,15k and 20k. at any rate the addition of a 20k reeflux seems to obsolete the regular coralvue line even more so than they already did (especially given the minimal price difference). just an observation but I guess I should ask how the reeflux 20k compares to the standard coralvue 20k as far as color (bluer/whiter, darker/brighter, ballast tuning differences ect)? cant wait til these bulbs are really out and about so I can take a look/see.

No problems. You will notice a "more blue look" from your lighting. Dimming down the ballast will not shorten or degrade the life of the bulb. On the other hand overdriving will.

[JRaquatics]

I also wanted to state to check with your bulb manufactures about the safety of dimming down their bulb. In my post above I was just referring to the CoralVue/Reeflux bulb only and what I was told by the manufacturer.

"Dimming the Reeflux bulbs with our ballast does not damage or degrade the life of the bulb." - CoralVue

The more this bulb burns in, the better it looks. I gotta talk my wife into letting me get two more so I can see what the whole tank looks like under them. :lol:

Still getting great growth and color. The 20k Reeflux still looks the same, bright like the Reeflux 12k but with actinics supplementation. I am really digging them. I hope to have time to get some par readings this weekend.

Do you all think the performance will still be the same if IceCap ballasts are used?

[deeznuts]

Well guys, I got my 400W 20K Reeflux bulbs yesterday and I have to say I'm a bit dissapointed , they look exactly the same (if not brighter) then my Reeflux 12K.
The light isnt blue at all but rather an intense white light with a tiny hint of blue - exactly like the 12K Reeflux.
I am going to let them burn in of course but so far it looks like I just spent 130$ for nothing.

Can anyone recommend a really blue 400W SE 20K bulb that will work well with my Coralvue E-ballasts?

Thanks!

[colubrid]

I am disappointed as well. On my Galaxy 400W ballasts these bulbs are whiter (and seem brighter) than the Reeflux 12K. Which ballasts are people using to obtain the 'more blue than 12K' look with?

[JRaquatics]

I am running it on a CV 250w dimmable ballast. The Reeflux 20k was indeed brighter than the 6 month old Reeflux 12ks when I first installed the lamp. But when I replaced the old 12ks with new ones they appeared to be all equal in brightness. Now after burn in the 20k has taken the brightness level down a notch and the 12ks do indeed appear slightly brighter. Like I mentioned before these 20k lamps are very bright and appear like a 15k bulb or an overdriven 20k.

This is what the market was looking for, a bulb that appeared like an overdriven 20k (Radium on HQI ballast) that wont hinder the life of the bulb. Pesonally I think CV hit it right on the mark of what they were trying to produce but the 20k # seems to mislead some people of what they consider a 20k is supposed to look like even though the spectral plots show were the bulb peaks.

Can anyone recommend a really blue 400W SE 20K bulb that will work well with my Coralvue E-ballasts?

Thanks!

I use a 400w Radium on a Coralvue Dimmible ballast and love it.

[Bolo Tran]

does anyone know how these bulbs compare to Phoenix 14K's? Are they bluer or whiter?

How would you describe the color running this combination and do you have any idea on the bulb life span with the Coralvue E ballast?

With the dimmables I can make it blue or white with a hint of blue.
Bulb life depends on how you drive it. You should get at least a year out of it if you drive it at 360w like it was desgned.

[NewSchool04]

I'm not sure what that means Mike. If I had Radium bulbs and ran them on my Coralvue dimmable 400W ballast full blast, what would the bulb look like and what type of life span on the bulb would I get. Unfortunately there is nothing to tell you how much you're pushing through your ballast, just a dial.

I was always under the impression that the Coravue E ballast couldn't power the Radium correctly. I think I remember seeing menard looking for HQI ballasts recently to run his Radiums.

[BreadmanMike]

400w Radiums are actually 360w bulbs. With a kill-a-watt you can measure how much electricity you're running through the ballast.

I'm running them with the ballast turned all the way up like you're looking to do. They are are white with a solid hint of blue, but not quite as white as they would be with an HQI ballast. My guess is 7-8 months before the bulb shifts, but with pootang having a par meter and living close by I can have him swing by to check the par out every few months to be sure I get the full use of the bulb.

If you will be down this way for anything Pat, you are welcome to see it and the 20k Reeflux in person. :)

[NewSchool04]

I'll definitely call Mike if I'm down that way!!! I still have to see the monster cube that I dream about almost every night. 48 x 48 . . . , my wife says I whisper it in my sleep! It's the dimensions, not your tank Mike!!! :)

So if you run a Radium bulb and turn it down 25% or a quarter turn, what type of color are you getting? Does it still fluoresce the corals?

[BreadmanMike]

You're welcome anytime Pat. :)

The Radiums look more blue and lose some of their brightness about 1/4 turn down, but not too blue that everything looks washed out and they have a nice flouresce. I honestly think they look the best on an HQI ballast, but the 20k Reeflux looks almost identical to the HQI/Radium combo. It really is something you have to see with your own eyes.

[AD87]

Mike what is your favorite lighting combo so far?

[BreadmanMike]

I like the 20k Reeflux the best with my ballasts. I moved the one 20k Reeflux I have to the front of the tank so I could enjoy the color more. When my Radiums need to be changed out, I'm 100% for sure switching to the 20k Reeflux.

If you have HQI ballasts and aren't looking to change, then the Radium would be my bulb of choice if you aren't running actinics. If you're running actinics I would choose the Ushio 14k/G-mann 14.5k. Here is the 14.5k G-mann with two UVL SA's and two ATI blue+.

Wow very nicely done. This should really help people decide which bulb to buy. I still favor the 12K. Though I will give the 20K a try in a few months.

[seawandrr]

It's time to refresh my 250w 10k's, so if you could get the PAR numbers up for 10, 12, and 20k when they're done, it would be very much appreciated.

Thanks!

[jakano]

Very interested to see how the DE versions look and the par numbers for them when they come in. I have really been wanting to get a 20K bulb but in DE land all par pretty much sucks at that temp range. If the color is the same as the SE version I'm sold I just hope the par is there too.

No they do not.
They are very white with a touch of blue, but if you are like me and love the blue look then this bulb is not for you.

I'm thinking of getting the Radiums but I dont know how they would look with my non dimmable Coralvue ballast.

[JRaquatics]

Here are the results of the Reeflux lamp fired exactly at 250w draw. Other ballasts may very on wattage draw. I just tried to keep the results for testing purposes as controlled as possible. These test were done on my personal aquarium with CoralVue dimmable electronic ballast and Lumen Bright mini reflectors. The tank is a standard AGA 180 with a depth of 24". No ozone or carbon has been used for 3 weeks or more, only a 100 micron filter sock (on one drain) and the skimmer. Test was done with one light, so no crossover light can alter the numbers.

http://i372.photobucket.com/albums/oo164/reefspecialty/Reeflux_group_par.jpg

Numbers may very slightly on other setups due to reflector, ballast and water quality.

[agsansoo]

Looks like I'll be trying the 20K's sooner rather than later after seeing the numbers. Thanks JRaquatics for taking the time and making the effort. :thumbsup:

[Tbduval]

JR,
Those are really good numbers for the 20k's. It is kind of surprising that they have better par then the 12k's. Guess the theory of higher K lower par is thrown out the window for these bulbs, expect the 10k's, but the coral does not look as good under the 10k's. Do you offering free shipping for the 20k's bulbs? Thanks!

Jeremy, what bulbs do you like the best for coral coloration.

[JRaquatics]

The Reeflux 10ks are nice for a 10k spectral bulb but have grown to like a crisp blue white look. I guess I prefer a cool look that the 12ks than the warm look a 10k provides. I am really liking the Reeflux 20ks and am glad I had the opportunity to test them out. In 6-7 months I will be switching all the bulbs from 12ks to 20ks. I really like the way they appear as bright as the 12ks but with a little more actinic pop. Now with the high par, I have no doubts 20ks will be my new bulb of choice.

[Tbduval]

Is it possible to ask Coralvue for a spectrum chart for their 10k,12k reeflux bulbs to compare thier new reeflux 20k bulb?

It's nice to have a chart for the 20K, but I would like to see their x,y values for 10k,12k. Kinda like compare apples to apples with their charts. If I use their 20k chart and compare the 12K and 10K charts of Sanjay's, it would be like comparing apples to organges?


Do you know where I could go for that info?

I don't know if other people would be interested in this info, but any help would be great.....Thanks

[JRaquatics]

One step ahead of you. We are trying to gather all the info on the Reeflux bulbs in both 250w and 400w and do an informational thread about them. But as of yet, We have not received spectral plots on the 12k and 10k yet.

[saltywet]

:thumbsup: Thanks for being on top of it already.

Now let see if coralvue can get it out to us.:hammer: ASAP :D

[JRaquatics]

CoralVue has sent in a request for the spectral plots. They said it will take some time though. But when I get them I will post them here for you.

[BreadmanMike]

Sanjay has spectral plots on manhattan reefs. He doesn't have them with Coralvue ballasts, but you can use Ice Cap's ballasts.

Nice work Jeremey! Love the photo layout... So did you get in on the Apogee PAR meter deal? Nice to see you with a meter:thumbsup: I just popped in a set of Reeflux 10K's a couple weeks ago so I should be measuring. Man I have these things turned way down right now but will measure them full in a week. I like the 10K's - a sunnier day than the 12K's. It's a nice change.

What I really want to test out is these new Reeflux 20K's you folks at Reef Specialty are pushing. LOL! I seriously can't wait to try these babies out. Funny thing is I always wanted a Reeflux 20K but never mentioned it to Mike or Dave. I guess everyone else did though so sweet. 20K's I will definitely be using. I think I am going to be switching the 10K's in and out for 3 week stretches. Just get a bit of a boost and then color them back up with some 20K's. I would not be messing with 10K's without a meter though. Your numbers are correct on 10K's and I am not completely burned in yet. I am up to 6 hours with them now and have them dimmed down a 1/3. Will have some pics soon...

The bulbs will look white and will shorten the life of the lamp by being over driven. DE vs SE is just a personal preference. I always say find a bulb with the color you like that works well with your ballast. SE lamps have a larger variety to choose from as compared to DE.

Get single end reflectors and run 400w bulbs made by Ushio, G-mann, or Aquaconnect. They are all HQI rated SE bulbs.

So they seem to have more par then the 12k huh. Any chance of doing the same for the 400w versions ?

No matter what the wattage the two bulb types should correspond with each other. So I would guess that the Reeflux 20k would produce more par than the 12k with the 400 also. Sadly I will not be able to test them at this time.

If they are single ended you want them so that all the nipples are faced upward. Do other bulbs have this appearance? I had a hamilton dual ballast m58 that drove one bulb harder than the other which caused a slight variance in color, hence why I switched to electronic ballast. So I would also try switching the bulb around to see if it's the bulb or the ballast.

[chads 385]

Hey Jermey if overdriving the bulbs can risk corals and shorten the life of a bulb why spend the extra money on them? Im assuming its for color matching correct me if im wrong. Also where are you taking the output readings for the bulbs? At the bulb or in the ballast to know if your overdriving them or not.
Thanks

[JRaquatics]

I have no way of reading the wattage at the bulb. So I just read the draw from the ballast. I know that you loose some power between the ballast and the socket but that's my safety net. Over driving bulbs have been really popular these days to increase par and alter the look of the lamp. Downside is that it does shorten the life of the bulb.

[chads 385]

So the testing your doing on the 20K Reflux is that with dimmable ballasts?

[chads 385]

Also does the Coralvue dimmable ballasts have settings on it? how do you know if your overdriving the bulb?

[aka_Willy]

There is a slight click spot on the adjustment knob and when you go past that spot you are in the overdriving range. Hope that is a good explaination.:D

[Rouselb]

Jeremy, Coralvue told me that their bulbs are rated between 6,000 and 8,000 hours at normal
running conditions. Thats roughly 2 years at 8 hrs a day. Most of us try to replace bulbs every year (specially if we dont have a PAR meter). Lets say you overdrive the bulbs on an HQI ballast, even if you got 10-12 months, thats about the norm for bulb life (for most of us that have an SPS dominate tank). What do you think? I have a few blue wave ballast, i was thinking of running one of the bulbs on that and comparing it to the other two that are on the dimable CV ballast.

[RokleM]

Honestly, I think that's an extreme exaggeration on Coralvue's part. I think most will keep 250's roughly 12 months as you mentioned. The only way I'd keep a bulb 24 months, even driving it exactly at spec or under, is if I was growing macro algae with it. I know for a fact, there is a pretty drastic swing (on color and PAR) on both Radium's and Reeflux 12k's (400w) when overdriven on a BlueWave7 HQI ballast by 6 months at the latest. That's typically where I swap them out when overdriving.

I have some 20k's and the adjustable ballasts on the way. Just waiting on JR and Mike to get the move on ;) I'm going to run them normal based on the PAR numbers I am seeing and see if I can push life out past 6 months. If I don't like the PAR/growth, I'll overdrive them.

[Rouselb]

From my understanding, most bulbs loose roughly 20-25% of their PAR in the first 3 months. After that, it remains pretty constant with a 5-10% loss for each 6 months after. In my case, i could turn the ballast down for the first 3 months and then back up after the bulb has burned in. Here is a good article on bulb life. I normally shoot for 12 months and then change, i like to keep the PAR values as high as i can for good growth. However, bulbs are expensive if you are buying new ones every 6 months. Interesting to note, the article states
"bulb would appear to still maintain 70% of its output at 18 months, 66% at 24 months and 63% at 27 months of use".

I tend to agree with RokleM. I swap out my bulbs every 8 months. I have seen a drop in par after the first 3-4 months and remains fairly steady till it is replacement time. I wouldn't recommend anyone to go over 12months on any bulb. I understand the degradation of a MH bulb over time but also feel that the reef likes the cycle of a bulb replacement over time. This is why I choose to replace my lamps every 8 months because that is what has always worked for my in the past.

HOw does this bulb compare to a Radium, in color and par?

How does the Reeflux 12k compare to the Reeflux 20k, both in the 400w version?

Is the 20k significantly more blue?

PAR?

[madmike]

I have been a bit disappointed with the 20K reeflux 400W version. I bought one to test and placed it in between 2 12k reeflux and I can't tell a difference in color at all. I am running the 400w dimmable ballasts and I run them at 400watts, not over or under driving them.

That's not good. Thanks for the info.

Anyone else have any input on the 400w comparison?

So is it white with not that much blue?

yes, virtually the same as the 12k. I thought it would make things "pop" a little more, but looks just the same. It has been burned in for about 2 weeks now. I just ordered radiums and will put one in and maybe take side-by-side pics of 12K, 20K, and radium on my tank and see which I like best. I run a radium 250w on a smaller 70 gallon frag cube and LOVE the color it brings out of the corals, even with no actinic supplement. My 225 has 2 72" and 2 24" actinics and it still seems a little too white for my liking.

The bulbs may be slightly brighter but I have not taken the time to measure with my par meter.

I'm running radiums right now and I also like the colors my corals have. But growth is good but not great. I was thinking of switching to the 20k reeflux because of the par #'s. I don't mind if it's a little whiter than my radiums.

[madmike]

all I know is that when I move frags from under my reeflux to my radium tank, the colors improve dramatically! The two tanks share a common sump, so different water params are ruled out.

[SolidDetail808]

Do you have pics of both tanks? I want something a little less blue and more par than a radium. Once my corals are grown then I'll switch back to the radium.

I went from a radium and a reeflux 12k on coralvue ballasts to the reeflux 20ks and I love the color. I personally see much more blue and "pop" from these bulbs than I got from either the 12k or the radium. The color is not nearly as washed out as it was with the radium. That being said I've only had them burning for three days now so the color could still change slightly.
Other than that I'm very impressed with them, now we'll see about longevity.

Looks like I'm going to get the 20k Reeflux soon.

I replaced my Aqualine Bushke 10k bulbs with the new Reeflux 20k bulbs today, and I'm really pleased with the new look. I wouldn't compare these to other 20k bulbs, because they're not dramatically blue like most 20k's. These bulbs are completely bluish white. My corals look SO much better underneath these bulbs vs. the old yellowish white AB 10k's.

Here are some pics, but I have to say these aren't very good representations of the way the color looks to the eye. I just have a point & shoot digital camera and this is the best I could get.

Before: Aqualine Buske 10k, bulbs about 9 months old

After: Reeflux 20k, bulbs are brand new

I like the RL. Makes the tank look much better.
