It seems there was a thread about them on the lighting forum. As I recall people who tried them said that they were too focused and didn't spread the light very well. I think they are similar to the spotlights seen on Japanese tanks. They are good for spotlighting a coral or two but not good for an all tank suplemental. That's why I would assume you see multiple spotlights on the Japanese tanks. Someone correct me if I'm wrong..... this is just what I recall reading a while back.
thats pretty much what I was thinking (the japanese spot-lit tanks) also they have a red one along with a blue one and a combo red/blue one also...was thinking of trying them all out
tell ya'll a little trick. After christmas last year. I found a strand of blue led christmas lights. has 60 lights. I just stapled them to the inside my hood. was a bit to bright so I took one bulb out and every other one is on now. works great for 8 bucks! Best investment I made so far!
I have 6 of the blue only over a 6 ft tank. If you look at the tank with all of the other lights on (6 80w T5s) you would think they are doing anything until you turn them off. Then when they are on by themselves, watch out, the colors POP.
ok I plugged in the missing bulb for twice the light. still not that great. much better in person.

oh and this is the white strand I got. I liked it better than the blue. the white led has a hint of blue like moon light. the blue just looked to fake.
