I just set two of these 100w led spotlights over a 220G 2 months ago, with dimable ballasts.

-easily spreads the tank
-12" above the water and may be too bright (testing stage, currently dimmed to 75%)
-costs about $250 more then what I would have spend on MH
-way less heat transfer
-brings out corals colours better then any light I have seen

cannot comment on coral growth as of yet with these

Nothing wrong with MH, but so far these are proving to be better IMO.

Ryan, with spots like that, depending on color, I could see these replacing MH. As long as growth is good long term. Keep us posted.

Those could be potentially game-changing...

I've read these high-powered canons are not nearly as energy efficient as the lower wattage LEDs but it sounds like 3 or 4 of these 100w versions would light a 400g nicely...

So their 50w versions are not dimmable by the looks of things?

There is a guy with 3 of the 100w 12ks over a 500 and he loves them. Here goes my evening/early morning ugghhh....

Looks like I'd need a controller to use the dimming however. I don't think you can program those drivers. They connect to a controller. Also... since these things are a single color (12k or the bluer one) you'd have to mix them if you didn't want a really blue or a 12k look. By the time you spread these over a tank and start mixing I imagine you'd see the 12k/blue banding in the tank.
