Hi Guys has anyone purchased the new Giesemann Stellar Hybrid Unit? Im looking to get one for a frag tank im building. Tank will be 970mm w x 600mm d x 350mm h. SPS only

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.

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

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.

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

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

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.

I sold my 72” for $950

These days take what you can get. The fixture is essentially obsolete.

I don't have a big tank anymore. Otherwise it would be great. Though I'm thinking of just setting up a 4' frag tank in the garage so I can utilize the light.

Don't sell it for nothing. Just store it imo

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.

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.

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.
