Very Cool LED's!!!

you mean this one? Vertex Lumina

Interesting way to do it. I'll be interested to see PAR readings at depth as this has no optics as well as PAR measurements front to back since all the LEDS are in the center. Even though the viewing angle of the LEDs is supposed to be 120 degrees there is a fall off in intensity off center.

Thats some cool fixture. But whoaaa, the price

Seems like the width coverage is there but with one fixture it looks like you would have to line your corals up single file across the tank! Ha ha! I wonder what kind of area it covers?

24" spread back to front.

I see that is what they say but I still would like to see PAR measurements. There will be a drop off in intensity off center and PAR may only be good in the middle 10 to 12 inches of the tank. It's a compromise. Try to get wider coverage by skipping optics and you have less penetration and lower PAR at depth. Add optics and you need more emitters to cover the tank.

I really don't understand their layout. I have a 48" array using 80 LEDs spaced over the whole 48" by 15". They have 128 LEDs in their 48" array all clustered down the center. Maybe that's how they get the PAR up without optics; by using so many more LEDS. But they probably could have accomplished the same thing using fewer LEDS spaced more evenly with optics thus using less energy and keeping the cost down a bit.

Personally I would wait to see some independent reviews and PAR measurements before spending that sort of money on this fixture.

I wonder if they are alternating the angles of the LEDs so the first one shines back, the next one center then next one front ect.. this will give them a sleaker look, alows the use of optics but still maintain PAR on the edges good. this is actualy how I was going to do mine.. guess I can't do it that way if some one is already doing it, got to think up something different again now

Doesn't look like that's how they are doing it and I believe I read that it uses no optics.
