they are no good yet. as I have stated befor the only one that comes close is the luxton star 5 watt and it is still at a level below NO lights. they do use them for plants and such on the space shuttle but they have a special rack that maintains them 1" above the plants.
so not only is this type of system not practicle in a reef tank but at 17.00 each for a luxton star I would estamate 8 to 12 of them for every 2 square feet of surface area for a even coverage. to compare apples with apples that would be a cost of 408.00 + tax just for the bulbs, still have to make a holder and a power supply. in the end this will compare to a 70.00 NO set up
so price wise they are still to high and thr afordable LED's are nothing more than night lights at a cost of 2 to 5.00 each.
