In Europe I see that Sewatec already carries it (www.sewatec.de). 600€.

Giesemann web states 55cm, so technically would be more towards 22inch. It is their entry level light so I guess they had to cut corners. It is a 150w fixture (50w per puck) so I guess they are being honest about the capabilities.
However, I'm thinking it could be a great cost effective way to add a couple of T5s and make it a cost effective hybrid option.

That is why I had said I was disappointed when I saw the Genesis...it didn't seem to pack a punch at all... I'm not sure, but the Mattixx loses in par to ATI's and I believe the T5 reflectors are one of the reasons.
I definitely feel like with exception of vervve, Gieseman LEDs are underpowered. Especially for lens-free clusters like what is used in aurora, Futura and tesla.

Yes, Viva uses the same clusters as Vervve, but due to passive cooling it can only powers them upto 50w per cluster, compared to actively cooled Vervve' 100w per cluster.
Genesis has the same clusters, but no active cooling is visible in the demo videos, so most likely it will run them at 50w or even less per cluster. Considering that there is heat coming from the T5s it may have fans but power will still be reduced, to compensate. It seems like Giesemann has been very conservative in respect to cooling capacity, as have noticed that Aurora's have massive heat sinks for 3 x 75w clusters in the 48" unit"

Couldnt find my own pics of the Genesis from Reefapalooza last year.. Going back on this thread found pics from my buddy Gcarroll, maybe it would help some view the light in better detail.
The Vervve led reflectors are really nice, but like others mentioned here previously, the lower wattage of the hybrid light might hinder its
performance comared to the all led fixture.
Im not too sure about the T5 reflectors either, maybe someone else can give better info on them, but my understanding is that they arent as good as the ATI's.

did you have this aurora before your spectra? which did you end up with?

Watts to PAR doesn't really matter. The 60" bulbs tend to have a little more PAR per inch but not enough to worry about.
PAR is influenced much more by reflector, cooling, ballast and how good the bulb is. T5s work like a blanket, not a directional space heater

Thank you. That is very helpful. I do find the 2 bulk 24" razor is super bright to the eye. I'm using it over what will be a coral acclimation/frag tank which is a 20 long at the moment.

Hello,
Someone to give me the dimmensions of the glass on a Giesemann Spectra 400hqi and for 250W hqi?
I want to know if I can put there 2 AI hydra 26 (in what direction = or ||)
Thanks
