LED experience for under $2

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.

Brett, agreed. But I'd have to see the 12k, it might look ok, or you could add a T5 tube for blue (somehow)

Agreed I'd really like to see one first. And I can't see myself just buying one to test either as it's still a lot of money.

After reading that RC thread I do get the feeling that these things are not quite as good par-wise as an actual fixture with 3w LEDs.

Ya, they're LED, but not in the sense of what most people consider LED for tanks. These especially would need to be proven long term.

True, you cant look at the wattage and compare LEDs. 50w of CREE XM LEDs will be much brighter than the 50w cannon.

I think we read the same thread on RC, they didnt get good reviews.
