Giesemann Lighting Club.

That is correct. I believe you are right too. I am dying to go for a Spectra as well, as it would be the cheapest way to light my 80inch long tank. I want to have a single fixture to minimize clutter. The 60'' Matrixx I would say is good for 60inches as the T5's coverage does not extend much beyond the length of the tubes. However, the T5's already put out a lot of heat so having a 72'' Spectra with 3x250w MH kind of scares me away from that...

[rtparty]

A 60" T5 easily covers 72". You will just have to be selective on what goes in the very edges of the tank. Move the rock work 6" off each side though and you're only having to light 68". Low light SPS or LPS will do just fine. For years I've run shorter fixtures than tank with little issue

[ReefCowboy]

A word of caution: I tried to run the original E5s in my Giesemann Matrix ii 8x80 dimmtec and they would only last a couple of weeks before they would die. The distributor sent me a replacement and the same thing happened. Than the ballast of the channel that was running them also died. Giesemann promptly sent me a new one but advised me against running the E5s on their unit. My !atrix was 6 months old at the time.

Thank you for the heads up. Glad to hear spectra should be ok.

Yes, but my tank is 80 inches and one of the ceramic rock structures is designed to sit flush to the overflow wall (it is a peninsula tank). So the rock work itself is a group of four islands that are 72'' in length. As you point out it covers 72'' assuming you do not have to light anything (or at least only low light stuff) on the 6'' that are left to each side of the 60'' fixture. I like units that run the entire length of the tank (or almost) and the 72'' Spectra would be the closest I could get (and the cheapest, as in Europe Giesemann units cost like half the price of the US. For reference, the largest Aurora Hybrid over here It would cost me 1.600eur, or roughly $US1.900). As a comparison, if I were to use Radion XR30's to get a decent coverage in my tank I would need at least 4, which would cost me over here Eur3.200 or 2x the Giesemann Aurora:fun5:

I've been using my Spectra for about a year and a half. I've had Radions and an ATI dimmable Sunpower. The Spectra is the best light I've used of all these. Why?

No fans. Despite three 400w halides and four T5 bulbs I don't have any fans running and don't need them. It's a dead quiet fixture. I do run a chiller and if I didn't the water temp would increase. In fact my old chiller failed the other day and my water would get to about 82F. With chiller I'm steady at 78F.

Metal halide. My corals love the MH. They grow towards the bulbs. They don't grow towards the T5s.

It's simple. While I liked the tweaking options of the Radions it was a pain to dial in and I always felt a need to tweak. I have installed a pair of Kessils into my Spectra between the MH bulbs. I did this because I like the florescence that a very blue LED can give. Actinics come close to that, but not as much as LEDs. You use Reefbrite so you understand.

The fixture looks great. Of all the T5 or MH fixtures out there it has the best looking design.

It just works. I've had no problems. Haven't had to change a T5 ballast, but if I did it would be simple. As I mentioned, I installed a pair of Kessils into the Spectra. I've taken the thing apart as much as possible. It's built simply and like a tank.

I have not pulled the trigger yet. My drawback is heat. I got a basement sump with evap cooling fans, tank upstairs in-wall with lights in canopy.
tank can hit 82 if i am not running Central Air. Based on this, i do not think i can go MH without a chiller. Expensive proposition for a good 1/2hp chiller

What are you running for a Chiller

Active Aqua Chiller, 1/2 HP. Bought it on Amazon for about $550. Looks exactly like the Aqua Euro chiller at Marine Depot but for less. You know it's the same model, just rebranded. And yes, you'll need a chiller for sure.

[gdemos]

Thanks i know nothing about chillers. The 1/2 hp unit i was directed to was over $1k

Hi all,

looking at an Aurora over a 5x2x2 mixed tank. If you had the choice would you run the 1500mm over the 1200mm?

I'm also wondering what peoples T5 combo is. Never used T5 so at a loss.

Thanks!

[ChadOwens]

Just got a new Giesemann Aurora 60" and can't get it to turn on. One of my T5s broke in shipping so I only have 3 of 4 installed right now. Would this prevent the unit from turning on? I can't get the LEDs on or any bluetooth signal.

No, its rooted.

Choss,

Some have done previously, but I find flaws with them since hey usually dont modify the mesh and therefore make it really tought to change bulbs later on.

I will try to make it so the mesh comes off from the top so the kessil lenses can be removed easily allowing the MH housing glass to slide freely.

Will use the kessils for dusk/dawn, bedore and after the halides go on/off.
Will also gry to run an EX5 on each side along with a blue + for blue supplementation.

I agree radiums for main lighting/kessils for blues cant be beat

I'm running a spectra 24" unit and two kessils on my new build. But I'm simply adding the kessils to the sides to cover a 42" tank. I'm in mid build so I haven't tested this yet. excited to give it a try.

[10Seconds]

After a week of running my 72" Spectra, my 220 tank varies only .5 degree higher than previously per the Temp graph on my Apex. I put a fan in the canopy and the temp graph went back exactly to how it was before, up and down 1 degree. I was worried that I would need a chiller, and I still may in summer (its winter here now) but so far so good.

What s=is the better fixture, the Spectra or Infinity?

[rtparty]

What s=is the better fixture, the Spectra or Infinity?Spectra IMO because the Radium is single ended

[ABruce]

I recently acquired a new tank and all the support equipment. The light fixture is a Giesemann four foot. It has four ho florescent tubes, two metal halides and a small bulb maybe a quartz. Circa 2010 If its the same age as everything else. Its a silver fixture if that helps. My issue is it has no ballast or power supply , the light has a cord to a multi pin plug. I have no manual and I am assuming to identify it you would need to have power to read the display as I see no serial number anywhere on it.
I could sure use some advice as to how to identify it and where to find the right components to get it to run.I would love to get it into service.
thanks

[moondoggy4]

^^^^^ Contact Coralvue and see if they have a adapter for the plug, I use a the Giesemann ballast that came with it. I think the only tricky fixture is the one with one plug for the whole light, my Infinity models has 3 plugs coming out of it.

I posted here earlier debating a spectra. I opted to purchase 2 Razor T5 54W units and leaning toward 2 Orphek V4 Compacts.

I just received the Razor and not sure how to change ballasts when needed. Any Videos or Pics? I took the end plate off and man its tight in there.

I also see that the wire insulation does not enclose fully in the plastic screw on grommet, not sure i like that. I returned one unit due to this and they sent 2 more (one got lost in mail then landed). Both of these have the same issue. Any thoughts?

Thanks!

I have a 24" Spectra and am having trouble getting the metal halide to fire. I have the Luxcore 250 W- 400 W ballast. I wired the ballast to the Spectra attachment as follows:

white to brown
black to blue
green to green

I first tried plugging it into my DJ strip. Turning on the power does not light the bulb. I can hear only the faintest hum in the ballast (so silent I am almost not 100% sure its there). I then tried to plug the ballast directly into a GFI outlet and it trips the GFI instantly.

Any suggestions on what is going on here?

[moondoggy4]

Buy a cheap bulb or get a used old one and switch your wiring and see what happens.

[choss]

I did give it a try (I have a second bulb but chanced it with my radium bulb). Nothing when I switched the wires.

[choss]

I thought I'd update a few additional pictures and maybe someone will spot what I'm doing wrong.

Here is a picture of the full connection - White to brown at the top, blue and back in the middle, and green to green/yellow in the center.

But when I look at the white plastic plug supplied by Giesemann for the ballast connection, I see fine print on the plug as follows (from bottom to top)

1,2, +, N, 3

Is it possible that the connections somehow don't go straight through? Is Neutral usually white?

[moondoggy4]

Do you have a voltage meter? You need to put the lead into the metal screw where the wires are to see if there is current. Warning 110 so you need the appropriate tester safety concerns When my Infinty went out the connector (they are much smaller than yours) and there is a little fuse in them. So I replaced and it works.

Whites neutral and if it Trips the outlet you have a short someplace be it the ballast itself or the connections.

Are you sure every wire is seated correctly and firmly.

I will test and try each one. So I have an update. I did switch the white and black wires coming out of the ballast. This would make sense based on the following color chart below

I now get a brief flicker when starting the ballast (and no breaker trips) but the light doesn't light. It just flickers for a second and that's it. At least I'm making some progress. Defective ballast?

Hey Abi, I run a 24" Spectra with 1x400 watt Radium 20k's and 4 blue+ t5's on my 36x36x16" tank and it covers it well. 30x30 should be no problem, depending on the height. I would go with a 400 watt bulb. It's an awesome light for sure!

It’s a little blue but not as blue as those led tanks:). A height of 10-12”’will cover the 30x30 with no problem.

I made my cube 32"x32" so I could have at least 250 par at the bottom edges with a single Giesmann Spectra. The coverage is excellent. Here's my tank when it was going well. I'm currently regrowing it (life got in the way). This tank is 32x32x26. Just be sure to use a SE 400 and not the DE 250s. I had the DE fixture, doesn't spread as well as the SE.

Thanks, I had a Giesmann Infinity 250w fixture. It was good on smaller tanks but spread and par is not enough for my liking in this size tank when running a bluer bulb. I like the spectrum of the radium more than any other halide, and in 250w it looks too dim to me from past experiences. Par numbers would be very low on the bottom of my 26" high tank with it. Of course it's doable, but 400w is so much better.

Thanks Abhishek,

I was running radion G4's for 4 months. They're excellent LED's, not a 400w radium, but the best LED alternative I have seen. I am planning a move within the next year and I wanted to sell the radions while they're still desirable. These LED companies shoot us in the foot by upgrading tech so often, at least ecotech does their best to make new technology integrate . But the real reason is because I want the best light possible over my tank for the end of it's life :D I'm trying to grow and color as much as possible over the winter. When I complete my move there will be a much larger tank in the picture :D I'll probably light it with a combo of Radion and T5 with my knowledge at the moment.

The t5's in the spectra absolutely suck. The reflector and no active cooling result in very low par. My ATI fixtures put out triple the par with the same bulbs. I'm currently running 2 coral+ and 2 Blue+ trying to get more par and the best growth at the moment. Visually, I always like 2 actinic and kz fiji purple run with the radium. It looks awesome when on alone and compliments the radium very well. I guess I change bulbs around the year mark give or take. The par is low for the t5 in the fixture so it really doesn't make a world of difference.

So basically the T5s are just to add blue to the halide and not really add up any PAR .
It's the 400 watt radium that does the bulk of the workload .
Wondering how good the halide reflector is then in the spectra unit ...

Other option is to run an xm or reeflux 10k bulb to get maximum PAR with 4 actinic ATI T5s to bring out colors in acros ..
I was always a big fan of 10k xm with actinic vhos ...

4 blue+ or actinic in the fixture aren't powerful enough to offset the white color of a 10xm, and the AC 10k is weird pink spectrum even with t5s on. Think normal output tubes lol. Seriously, the T5 output sucks in the Giesemann. I don't even know what bulbs are still ion existence, but an aqua connect 14k would be my next choice besides a radium. FWIW the Spectra halide spread better than the Sfiligoi fixture that I had before this, but it's not as good as a full side diamond style reflector that you would retrofit... Those reflectors are absolutely huge though, they must be hidden in a wall or canopy etc.

Congrats on the tank, absolutely beautiful. Im back building an sps tank and have a new Spectra with 2x250w radiums. Im undecided on the T5’s was thinking on adding actinics and KZ Fiji Purples, as you mentioned. What is the difference between the last one and ATI Purple+?

The colors of your sps are very nice. Reminded me what halide results look like

Thanks. Unfortunately, after about 1 1/2 years I had a big die off. The tank grew very dense, flow became a problem, corals shading each other became a problem, and my work schedule was the main problem. I'm growing it all out again :). As far as the fiji purple + purple+ I don't see much of a difference, either would be fine.

Spectra/Infiniti owners: Are you running the splash guard on your T5 or leaving it off? I can only imagine the temps are brutal with the guard on.

[choss]

Has anyone attached a nice looking shield of some sort to eliminate the glare from the MH in the Spectra? I'm catching some glare off the reflector at the moment - my light is 9" above the water and it is really visible when I sit in my easy chair about 5 ' away. I was thinking of attaching a high quality strip of some sort that will compliment the fixture but shield the glare.

Has anyone attached a nice looking shield of some sort to eliminate the glare from the MH in the Spectra? I'm catching some glare off the reflector at the moment - my light is 9" above the water and it is really visible when I sit in my easy chair about 5 ' away. I was thinking of attaching a high quality strip of some sort that will compliment the fixture but shield the glare.

I guess the ghetto lischas piece of cardboard would not suit your taste.:beer: That is what I am using right now.:spin2:

ZacK: I have an 84x42x26 peninsula setup and I ended up adding supplemental T5 to my 6’ spectra.
2 2-tube 60” T5 and 2 2-tube 24” on each end. Seems to work well.

Do you have a picture of what that looks like?

[reefrf]

Can you show us how you attached your Reefbrite strips to the Giesemann? I just received mine but find the XHO are about a 1/4” longer then then the Giesemann fixture. Plus there is a protruding part (bushing) sticking out on each end for the screw to go.into. I would have to bend the L brackets that come with the Reefbrite to make it work. I’d prefer to have a clean look for this.


I love my Spectra, for me MH/t5 is the only way to grow corals but the limited control stinks. I decided to supplement my Spectra for a bit more light and a lot more control. I really wanted some dimming as well as the color pop of blue LED for evening viewing. So on top of the 2, 250w Radium and 4, ATI Super Actinic I've added 2, ReefBrite XHO Blue and 1, AI Hydra 26 HD.

I know this much light is completely unnecessary and potentially dangerous but I'm really enjoying experimenting with ramping schedules and acclimating my tank to the new lights. I'll never run them all at once at full blast but with them all turned to max they put out more than 1000 PAR at the center of the tank on the water's surface.

HA - I may consider something temporary that is similar. Of course an expensive solution might be to add a reef brite across the front but I already have lighting overkill on this tank.

If you were going to say spectra vs powermodule, I would of gave it to spectra. Halide is still king in my book. And to have a a possibility to have an 8 t5 vs a 4 t5 fixture coupled with leds (powermodule vs aurora) the powermodule will have more spread, even coverage, ATI has proved to be the best T5 manufacturer in the hobby, and the cost to buy it is cheaper I believe. LASTLY why would you ask a question like that about a competitor on a giesemann thread unless you were prepared for both answers. Did you ask on here to be told aurora? That's what it looks like, if so that's kind of a time waister, you should just buy what you want

He can go persuade himself no? That's like saying that sharks are not safe but you prove it by cutting your hand before putting it in the water.

i wanted both answers thats why i asked you what made you pick the powermodule over the aurora. i also posted this in the ATI thread too. And im on the fence about the spectras, i really dont want a ton of cords behind my tank, the heat of a MH, the extra electric bill and ive never ran MH so i dont know much about them at all

[Joe0813]

if i go the spectra route they only come in a 72 inch fixture... my canopy is only 73 inches, would that be an issue for heat and air flow on the light?

[moondoggy4]

^^^^When I had a canopy with dual 175 I had put in three fans all blowing out, so you will probably need 4 fans.

[Joe0813]

i was thinkin install two of the ice cap fans on the canopy itself and then put one or two of those clip on fans on the other end pushing the air towards the ice cap fans

[moondoggy4]

I had two of my fans on a controller, so it all worked well for me.

[Mark SF]

Just picked up a 24" Spectra on eBay for a killer price. Now the decision for the ballast - I was thinking Lumatek to run a Radium 250w on the HQI setting. I've also seen recommendations for the LuxCore ballast, but I just can't see how that would be better than Lumatek?

Anyone have experience with both?

[choss]

I use the Luxcore on my 24" spectra - running the 250 setting now but I like that I can go up to 400. No issues, works fine.

Oh nice - how's the noise/heat from the Hamilton? I know they tout their ballasts were made specifically for the Radium bulb. Is this a 250w or 400w?

They groan like a old man when they start, but I do not really hear them much once they are up and running. I have the 250 M80 ballast, the correct ones. You cannot use the 400 watt models anymore the new 400 watt bulbs cannot handle the punch when they start. You need a modern controller to use them, I have a very old controller but if the elec. goes out they will not start for 15 minutes so a cheap light times is out of the question.

[Joe0813]

Just got my spectra and did the burn in period for the lights. It definitely heated my garage up a decent amount. Does anyone know how many amps a 72 inch fixture pulls?

[Joe0813]

Bump to see if it can go on the same circuit

[moondoggy4]

^^^^^^^Your lighting should be staggered, don't have more than 1 MH start at the same time.

[Joe0813]

^^^^^^^Your lighting should be staggered, don't have more than 1 MH start at the same time.

can i leave it on the same circuit though and just have my apex have one turn on, then 30 minutes another one and finally the third one 30 minutes after?

[moondoggy4]

Yes that is what I do, you have a electronic so it should be easier on the starting but a M80 ballast is a lot more abrupt more like a punch then a fast flicker so to speak.

[Joe0813]

all set up... i have the actinics come on at 2 for an hour. Then at 3 the left MH, 3:10 the middle and 3:20 the right. The halides shut off at 10 and the actinics shut off at 11.

[moondoggy4]

Well in the end stay with that cycle, maybe run the halides for a hour then ramp up 15 minutes every month unless you have a high demand right away, if so maybe just go 4 hours to start.

I have mostly SPS. so far everything seems to be loving the halides instead of the crappy ecotech gen 2

[choss]

I finally have my tank up and running. I have to say that I absolutely love the Spectra/Kessil combo although I think the Spectra could actually handle the 42"X24"X21" tank just fine alone. But the combo of shimmer and late evening viewing under LEDs was worth the investment. Here is a short video. Hope you enjoy.

Hey guys looking to buy a 36” spectra please send me a text if anyone is selling one

6198552667

[moondoggy4]

^^^^^ Not that I am aware of but they do not make a 36" model.

[Joe0813]

seems that some of the corals are not a fan of the spectra

[moondoggy4]

^^^^^^ Can you raise it up.

[migs671]

^^^^^ Not that I am aware of but they do not make a 36" model.

Wow really that sucks
I saw on coralvalve website that they had a 36” one

[migs671]

Can I get away with a single 400w radium 24” spectra on a 36x30x18 tank or should I go with 2?

Or 1 spectra and 2 xr15 on the end of the fixture

[Joe0813]

^^^^^^ Can you raise it up.

Unfortunately not. I'm at around 10 inches off the water too

[moondoggy4]

^^^ How long are running the MH on for? Can you shorten the timeframe?

[SBPD428]

I am in the process of building a 375g tank. I have decided to run MH With LED supplementation. Tank dimensions are 96" x 30" x 30". I will be using Lumen Bright SE Large Reflectors and have decided to use the Giesemann Megachrome Crystal 17,500K SE 400W bulb. Can anyone recommend a good ballast for this combination. I know choices a slim theses days. With all the reading I have done everything points to Hamilton, Luxcore or lumatec. Are any of these the best or am I missing something better? Sorry in advance if this is the wrong thread.

[Joe0813]

^^^ How long are running the MH on for? Can you shorten the timeframe?

3pm to 10pm

[moondoggy4]

Can you shorten the time period? Will affect other corals or just try to find a darker spot in the tank?

[migs671]

^^^^^ Not that I am aware of but they do not make a 36" model.

I guess they do make 36” unit but it’s the iridium
I just purchased one from a retailer

That should work well. Even 250 W would be fine. I run my 24" on a 42"X24" tank (21" high) and I suppliment with two Kessil's but more for late evening effect then for the corals. I think the Spectra can handle it just fine.

[sus]

Those that are running the spectra, how high off the water are you keeping it?

I use a single 24" Spectra with a 400w Radium and it easily covers my 36x36x16" (100g) tank.

I don’t believe this is new it’s there “iridium” model which is powder coated instead of the regular smooth finish on the normal spectra.

If you look them up on eBay coralvueoutlet they have them for $950 with bestnoffer accepted I got mine for an amazing price

[ReefCowboy]

The iridium is the finish we get here in the US. Some importers get the silver and white which is common in Europe, but we only have the first option which is the one I have and is not as elegant as the European versions.

As far as length, I'm sure you can import a 36 inch. BRS doesn't carry that size.

I ordered my 24” unit recently from CoralVue as well. I received a silver unit, but was hoping for the polished metal looking one that I saw in the photos. Was curious if this actually existed?

I’ve searched high and low and have only seem to have found three color options: black and gray/silver (which I received) and the newer white color which appears to be special order.

That 36 with two halides has got to be a monster. par and heat wise both. These have no active cooling. that would fry the T5's IMO.

[mtlreef25]

Hi all,

bought a Giesemann Infiniti 48'' 2x 250w 4x 54w T5. Weird ballast configuration... only 2 chords are going out of the fixture. One is a normal ballast connection for MH and a chord for T5s and the other ballast is for one side T5s and 1 MH (white thin plastic plug). If I eventually need to change that ballast, what do i buy instead of the Giesemann ballast. Didn't find anything after many searchs... Help would be appreciated! :)

Does the 36” really come with two halides? I’d be surprised, that one pictured almost looks like it was modified.

I’ve heard of people using the ATI T5 ballast in the Spectra, but my concern would be that the ATI ballast was meant to overdrive the bulbs (at least what I remember) and there is no active cooling.

[choss]

I'd be very interested in the heat effect on the tank with the 36" spectra. I did look at it but opted to go with the 24" and two LEDs to suppliment which I'm quite happy with. My tank goes from 77 to 79.8 when the light is on. So its not too bad. I will be adding a GHL cooling fan this weekend just in case. It gets hot here in New York in the summer.

[lancesmith1]

I ran a Spectra at one point in time for a few months. I just couldn't get past it not having active cooling.

Guys,

I'm setting up a white RS Reefer 425XL + white GM Spectra,
should I go 2x250W or 2x400W?

According to BRS review 2x250W has lower PAR than ATI Sunpower 6x T5.
Some of my friends say that there is no difference between 250W and 400W,
and as they changed the bulbs they only saw difference in electricity bill, not in colors and growth.

It's going to be 100% SPS Zeovit reef.

I heard that in Europe 400W version has got bigger reflectors than 250W version.
It seems that in US they sell only 400W version labelled as 250/400 - you just have to choose the bulb/ballast wattage.

I can't imagine that you wouldn't get more par from the 400 W version. Personally I like the shimmer v. the flat look of the ATI. But I think both are good choices

I’m excited to follow any build thread for your new system, I’ve tried Zeo in the past with no luck. Just getting back in myself.

I wouldn’t care about the PAR delta between these two fixtures...for me it would be preference of aesthetics, and the shimmer is going to win that debate for me. Also to note, PAR from MH is highly dependent on the bulb spectrum. So the BRS review, while amazing they even go through the effort, isn’t a perfect example.

There are many combos, but no denying T5 coral coloration ability and even PAR distribution. Still, that “look” from MH cannot be imitated.

I was thinking worst case scenario I would add a Reef Brite XHO strip to my Spectra for more coloration balance and actinic support if I needed to move to a higher PAR, lower kelvin bulb.

I already have an ATI Sunpower 8x T5 and I think that I could use more light at the bottom of my tank.
Hence I want Giesemann 2x400W as 2x250 is comparable to ATI Sunpower according to BRS review.


I’m excited to follow any build thread for your new system, I’ve tried Zeo in the past with no luck. Just getting back in myself.


And I always had worse results when I tried to switch from Zeo to something else.
Now on my new build I wan't to achieve these pastels without compromise :D


I wouldn’t care about the PAR delta between these two fixtures...for me it would be preference of aesthetics, and the shimmer is going to win that debate for me. Also to note, PAR from MH is highly dependent on the bulb spectrum. So the BRS review, while amazing they even go through the effort, isn’t a perfect example.

There are many combos, but no denying T5 coral coloration ability and even PAR distribution. Still, that “look” from MH cannot be imitated.


Yes T5 will provide you with everything you need.
Perfect spectrum, uniform illumination, amazing colors, healthy corals.
Actually T5 is the only light source that can give that fluorescent colors to your SPS and make them look as they were glowing from the inside.

But...
I tried HQI burners on my tank and I loved how the tank looked like and how the corals responded.
So for me it's - not as fluorescent colors but overall more interesting looking tank.
Also I had an impression that my SPS had turned healthier under halides.

Anyway Spectra is a combination of both worlds and for me after years of experimenting with reef illumination - it's the only way to go :D

Question for Giesemann spectra users -

Planning for an acro only 48 inch x 36 inch x 19 inch tank and needless to say need some nice coverage to cover end to end for acros in a 26 inch depth tank.

I was looking at getting 2 giessemann spectra with 4x24 watt bulbs each . I might run 2 400 watt radium or crystal bulbs but wanted to know the coverage of teh reflectors .

I know they are probably not as good as my lumenbright large reflectors but the modularity of it makes it favorable if it can cover the footprint.

Abhishek

why not just get a 48" unit?

I have a 36” spectra over a 48 x 28 x 20 SPS tank and is a perfect size. I was initially going to to go with a 48” fixture until I heard they had a 36”. The 36” minimizes light spill while providing great coverage.

[abhishek@1985]

Well gives me options to hang each 24 inch unit along the depth of the tank over 2 islands if I aquascape that way .

Got it. so you will hang them so the 24" length covers the 36" depth of the tank X2. I think that would work really well. and you can hide the cords off the back. I like it!

I’m running 250w Radiums in M80 ballasts. ATI Blue+ and Giesemann Super Actinic+ for the T5s.

Thanks guys !! This gets interesting now . I have 2 choices :-

1. 2x24 inch spectra with 8x24 watt T5s hung along the depth of the tank .
2. 1 48 inch spectra with 8x54 watts T5s hung along the length .

With option 1 - much tidier setup where I can hide cords and many more configurations possible .
With option 2 - simply covers 48 inch length and more PAR .

Confusion !!!!

I suppose a third option is to run the 36"spectra w. 2 MHs and 4 T5s, if you want to avoid light spill. But I think with the two Island format you should just go with the two 24". Just as an aside, I run the 24" spectra on a tank that is 42"X24"X21" and although I supplement with two Kessil A360WEs, I think I would have been ok with just the 24" spectra. The Kessils give great night time viewing and add some additional shimmer. But I do think the 36" Spectra could work for you.

[Mark SF]

One thing to keep in mind is I remember reading that the PAR/inch on the 4’ 54w vs 2’ 24w was much higher according to a thread on the Zeovit forum (from memory). Obviously the math shows a 12% delta from the start, but I want to say it was higher than that.

[choss]

There are often a lot of conversations or threads around LEDs v. other forms of lighting, and the argument that LEDs are cheaper over he long haul is often a case for switching. Since I am running all three forms of lighting, I see the merits of all the options. But one thing I can say about LEDs is that they seem to fail a lot more frequently than other forms of lighting. On my original Kessil A360WE, I had to have the light replaced once (under warranty) and now the replacement light has failed as well. The replacement light is fairly new (about 1 years old) but of course not under warranty since they are holding to the warranty for the original purchase date. So I now have to replace a $360 light. Sure all forms of lighting can fail but I think with LEDs we probably should expect these lights to be replaced every 1-2 years. Once you factor that cost in I no longer see them as a cost savings v. traditional lights.

[ReefCowboy]

Nvm ... I found it, not doing that. He actually took apart the kessils.

Im doing that, retrofitting kessils in.. Not sure if Ill use three Kessil A160’s or two A160’s on the sides and an A360w in the middle. My tank is 60” so I might be ok with three A160’s.

I thought of adding the Orphek led bar, but it takes all beauty from the Spectra. Retrofitting kessils is a bit of work, but if done carefully it will give the Spectra a much nicer look with the led appeal for pop and dusk/dawn

[biecacka]

Any pictures of your project?

Unfortunately I havent started yet, but will take lots of pics and documment so others can do it with more understanding on whats involved.

I absolutely hate the look of the spectra with hanging led bars on its sides.
I actually placed an A80 yesterday blues only by the spot I would retrofit the Spectra and it did look pretty good. My only issue is the MH reflectors leave too big of a gap between the leds so I will need something with better spread and power such as the A160.

Honestly Giesemann would gather so many customers if they added leds to the spectra. They spend so much with thise nonsense led only units that fall on their faces over and over, when their best fixture ever could still sell if they added what most people care for leds which is blue pop and dusk and dawn

[Jay Ellul]

I’m pretty sure there is a Spectra with programable moonlight led?

It is a 700 hundred item and most items do not sale that fast. I do not believe that it is obsolete technology, maybe a victim of pop culture. I guess it is hard to compete with 10,000 hours of run time.

[jjencek]

If you were going to say spectra vs powermodule, I would of gave it to spectra. Halide is still king in my book. And to have a a possibility to have an 8 t5 vs a 4 t5 fixture coupled with leds (powermodule vs aurora) the powermodule will have more spread, even coverage, ATI has proved to be the best T5 manufacturer in the hobby, and the cost to buy it is cheaper I believe. LASTLY why would you ask a question like that about a competitor on a giesemann thread unless you were prepared for both answers. Did you ask on here to be told aurora? That's what it looks like, if so that's kind of a time waister, you should just buy what you want

I have the same problem trying to decide between the LED hybrid from ATI and Giesemann. Because I will be using only the 48", they both have four T5s.

Was the number of T5s your biggest argument for the ATI? How do the LEDs compare?

BTW because I am in Europe the cost is about the same.

[Johnseye]

Why would you think it's obsolete? I started out with Radion LED, then moved to a combo of LED and T5, then to a combo of MH, T5 and LED. The LED is just there to bring out more fluorescent. I have never had better growth or color than I do with MH. The only reason I would move back to LED as a primary source would be to lower my electric bill.

Ooops - I just found out there is a 8 T5s powermodule in the 48" version. I got a 90 gal tank. Do I need 8 T5s?

More is always better. Better coverage and better spectrum. More also equals higher elec bills. If you're ok with that then why not?

There are other consideration factors like space, brightness and look or appearance of the fixture.

[Chad_P]

I thought I'd update a few additional pictures and maybe someone will spot what I'm doing wrong.



Here is a picture of the full connection - White to brown at the top, blue and back in the middle, and green to green/yellow in the center.

Good score, I would just run it. But you can do what you want, people have removed the MH and installed other leds but you will probably ruin the Giesmeann light.

:fish1: Next time you try LED's, go with the Mitra's they grow and color up coral just as good, if not better then M/H , T5, or VHO bulbs. Been there and done that with all the combinations possible, and the Mitra's are hands down the best and easiest Led lights to use. :fish1:

With LED I think the biggest consideration is the amount of light per square inch. How many fixtures do you need across your tank. There are undoubtedly many LED success stories and those I've read use a high concentration of lights. It can absolutely be done, but at what cost and how easy?

While I have customized my Spectra to include LEDs they were for color. I have never experienced simple consistent growth like I do with MH and T5s, but I also did not line up LED fixtures end to end. I went with 3 over a 120, then I added T5s which improved things. Then I tore that tank down and went with the Spectra.

Also, anybody ever tried to retrofit fans for cooling the T5s ?

Welcome to the club. The Infinity's and Spectra have great controllability, 2 T-5's on 4 T-5's on Mh on MH with two T-5's or MH w/4 T-5's. You can easily do a stepped ramp up Midday and then sunset.

hello As of now I only have one cord for the t5s I am thinking about doing a mod to add in another cord. but if I use the reef brite s they would come on first. and then 2nd all the t5s at once I am not sure if its worth doing the mod to add in a 2nd cord.
also I hear that sometimes these fixtures get real hot and sometimes the halides over heat and shut off I was thinking adding a small 3 inch fan on the oppsite side of were the cords come out what do ya think ? thx

:fish1: Hi, it's not so much the amount of light per square inch, as it is you need to use the same wattage for both fixtures. Example, if you are using 1500 watts of M/H, T5 lighting, you will need 1500 watts of LED lighting. It is very easy to do, but like you stated, the high end LED light fixtures are a bit pricey. :fish1:

[Chad_P]

Dumb question, but when changing bulbs do you guys take the whole fixture down or just leave it hanging? I’m using the Giesseman brackets curious what the best way is. It’s not easy to take down with one person carefully and I worry about shaking/bumping it too much when it’s hanging. Probably over thinking it.

Hello All,

I have a 48" Giesemann Aurora. I bought it from a scratch/dent sale BRS had about a year ago. I just got around to setting it up on my tank! I love the build and look of the fixture BUT I have an issue with the LED's In mine and was wondering if anyone here had any ideas/troubleshooting steps or experienced it themselves..

My Royal Blue channel on the LED's is not the same color across the fixture. 1 Led cluster is royal blue, the other 2 clusters emit a different shade of blue, almost as if the driver isnt sending the correct current to them. It is impossible to get in photographs, but picture the Marine blue channel on 2 pucks, and the royal blue channel on the 3rd.

It is noticeable even with all channels on and t5's. I have contacted giesemann and they have let me know they have no idea how/why this would happen, but I can purchase replacement LED clusters at $160 per and the control board for $120. It would cost me $600+ to get 3 new clusters and the control board.

Do you guys have any ideas of things I can try before just throwing cash at the problem?

the Spectras allows you to pick voltage and comes with an outboard ballast so it will come with the right plug...the Infiniti ballast is mounted in the fixture and the fact they come will the bulbs is a good deal.

You don't get to pick the bulbs apperently it all comes with mega Chrome. Secondly it doesn't ship with ballasts. Thirdly (I don't follow what outboard ballasts means

Just a guess here but an on board ballast would mean built in to the fixture.
So an outboard would mean a separate unit.

you order it with dimmable ballast

[Zacktosterone]

Nah I just got the reg. Can you get it with dimmable? 60"? I'll ask

[moondoggy4]

Congrats, I thought that you had a Spectra before, did you sell it?

I was never able to get my hands on one. Coral vue is brutal to deal with. Took me six years to get this light. I'm not going to go on a rant about my experienceS with that company, but I just found out that I could get it direct so I immediately bought it

Yes if ordered direct from Giesemann you can get dimmable T5 ballasts and other options installed,also you should be getting a step up converter to run 120v to 230v ballasts and yes Coralvue sucks for there service I hope they handle Philips Coral Care better.

120v to 230v ballasts?
I emailed them and asked them about the dimmable ballasts. Just waiting for a reply

The MH ballast that come with Spectra/Infiniti are 230v 50hz and you use a step up converter to run them.

I'm sorry I don't know what that is still. What does it do? Does it run the T5's? And give you the ability to dim them?

Europe run's on 230v/50hz and North America run's on 120v/60hz.

Spectra's are wired up to come with external ballast boxes regardless if being sold in Europe or North America.When bought direct from Giesemann it will come with a 230v ballast just for the MH's because Europe no longer mfg's 120v MH ballasts.

So to run something that requires 230v but you only have 120v from your wall outlet you would use what's called a 'step-up / step-down transformer or converter, it's a voltage booster or regulator.

oh ok i took care of that! they're good to go they said to be completely american

I realized you ordered the Spectra which will not come with MH ballast for the North American version you will need to purchase them and if your going to run 250w bulbs I recommend Hamilton M80 ballast.

I have M80 ballasts Already and they come with the wire connectors

I've got 36 wide x 18 wide x 21 deep, mixed reef tank with a couple of SPS. Does anyone think that a 250 watt 24" Infiniti would get me the spread that I need to cover the tank or will it will be too small.

you be fine

[JennyFlow]

For a 30 inch deep tank am I better of with 250w or 400w 20k radiums?

Also, with the spectra, how muted is the shimmer? Do they T5s lessen the shimmer alot or just a little?

[Zacktosterone]

it arrived from Germany! I'm going to try to set it up this weekend

[dccdennis]

Vervve owner here, they're still in the box until I can locate a par meter. Unless another vervve owner wants to share some insights on height and intensity?

[GaZZaW]

Im thinking of putting my Vervve led`s in a stellar fixture to combat shading.
I have a 1.2M (48 inch)Tank (reefer xl425) but im not sure which fixture to get. the 1200mm (48 inch) or the 900 mm (36 inch)

[gimmiks]

I see that the stellar light fixture are on sale at marine depot .could this mean new models coming out ?

Anyone in US doing Geissemann troubleshooting or repair? I have a Geissemann Matrix II Dimtec with 8 T5's. I plugged it in, there is power to everything, but it won't light up. All 8 T5 does not light up and neither does the fans on top. So I don't think it is the ballasts. I'm thinking it is the boards as the fans doesn't turn on either, but not sure how to test it to see if is as there are no literature. Any Geissemann reps on this site?

Am I missing something very simple to try?

[Infinite0180]

Anybody selling a 24” spectra?

[tgbaby1]

Anybody selling a 24” spectra?


Would a 36” work?

[Infinite0180]

Unfortunately not. I did find a 24” Infiniti i picked up for a steal though! Pretty pumped about it!

To owners of Giesemann Stellar fixture.

Are you happy with it? What LEDs have you added to it?
I was contemplating getting a Giesemann Aurora V8 (from Germany) when some pointed to me that the LEDs are not the greatest as there are better options with superior lenses and optics (like the Kessil for example).

So now I am considering a Stellar so I can add any LED lights I want and also give me the ability to upgrade them in the future should the technology improve significantly. I need the 60" length for a 180 g reef aquarium.
