this is kool.
hope the price drops within a year or two ;-)

just a matter of time before we start seeing high powered led's used widely, replacing the need for halides in our reefs. right now, the application is relatively new and prices are just way up there negating the benefits of going with LEDs.
at my work, one of the application guys was using one of our LED driver chips to light up an LED array that was pretty bright relative to my 2x32watt PC setup on my nano. the power consumption of the LED setup was a whopping 8watts!!

went to the calculate savings button clicked calculate and it said savings in 5.4 months... then I scrolled down adjusted for the fact I don't have 4' VHOs I already have the equipment so that can't be considered a savings, changed the cost of bulbs (I don't buy $90 bulbs) etc etc... then clicked calculate 87 months until I break even... yeah no thanks ... maybe if they come WAYYYYYYYY down and many others use it I'll think about it.
Although it never gives any specifications on the system, I've seen "replaces a 250w bulb" but what does? One little section? or a whole 72" one is the equiv? One interesting thing is that it says that 20kK has more PAR than 13kK? I find this interesting, probably an artifact that white LEDs aren't as efficient as blue ones.

You could conceivably run these off solar panels too! (or have a skylight) I mean, their natively DC devices right? And then when the sun went down, so did your lights! I can't wait until the LED's are reasonably priced and DIYers jump on it!

Yup you could Vince! Although you'd have to rewire them since they have ac-dc adapters built in (at over 2 grand a pop though don't know how much I'd want to experiment with that 
). Best thing with running them off solar panels is as the sun sets the voltage drops on the solar panels giving you a dimmed effect and dusk/dawn for that complete reef experience! Including cloudy days!
One thing I just never got from them they claim no need for a chiller due to lighting yet I was under the impression that a HUGE majority of the heating from lighting was due to the light energy going into the tank, not so much because you have a hot bulb, so seems like 250w equivilant of LEDs will heat your water just as much as a 250w bulb.

haha believe me, ive already asked him to look into it for me.
a limitation is getting the LED manufacturers to hook up more free samples but then again, im being a cheap *** in buying LEDs that are a few dollars each.
also, id be worried about shielding the circuit board properly from all that moisture we see in our tanks..the last thing i want is finding my cube drenched from the sprinkler going off from a electrical fire..haha
ill have something soon...
I am waiting for the "retrofit kits", if they ever come out . I had been following that web site for a couple of months now. The ability to change the light output kelvin rating was pretty nice along with the whole "all in one" aspect of dawn/day/dusk/moonlight not to mention not needing actinic supplementation, etc.
But as others stated, they didn't really give alot of data about their equivalent performance. I thought I read somewhere that they were equal to a 14K 250W MH for PAR, but even that leaves alot of wiggle room for what the actual performance is...

I don't think so.
There are like 50 of them.

But there are many of them.
