1 watt LEDs, probably generic chinese emitters (which have lower output then the better known brands). I wouldn't bother unless it was for lower light applications. Softies etc.

the problem with that is you also have to know what spacing the LEDs are on the fixture or when you order your optics you might order some that require to tight of a spacing and creat a bunch of min spotlights.

Good point.

Anyone heard anything on the Maxspect lights? They are using Cree now and seem to have a lot of bang for the buck.

They seem alright but I don't like the idea of using the 30W LEDs (not Cree as Cree does not make this type). Those LEDs are nowhere near as efficient as 3W LEDs, especially something like a Cree. Also, they create hotspots right under them which means you will have to more picky about where you place various corals.

Vertex has just put out a LED lighting system and it looks incredible. As soon as I get the specs and pix I will post them

The Vertex light does look very cool...........

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?
