i have learned that there are alot of led geniuses on a led forum somewhere on the internet- apparently the solaris leds are not strong lol- there are a few cree leds that you can over power the crap outta the led but you need to mount them on heatsink metal or else they will get really hot. I think that 1 or 3 watt leds focused over a 90 degree range at one foot should not burn the corals im hoping.
