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.

Regards,
Abhishek

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.

What wattage metal halide bulbs are you using ? Is it a mixed reef for you ? Mine is only acropora tank with may be some montis if at all..

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!

That's the idea exactly !! Could you tell me the width of a spectra fixture ?

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

Tank is SPS dominant, 80% Acropora.

I believe the width is 17”.

Does anyone know where that post is where a guy installed Kessel lights inside his Spectra ? I tried searching but no luck

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 !!!!

Regards,
Abhishek

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.

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.

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.

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

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

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

Built in moon light and dimmable t5

What more would you need?

These are the best light in the game IMO I’d gladly swap my hybrid powermudule for one!

Do you think anyone will buy my Geisemann Infiniti 48"? I've been having trouble selling it. It's a custom polar white from Germany too.

Just dropped my price to $700, but the demand seems to be really low? What's the going price these days? Unfortunate since I paid a ton for it to get custom ordered.
