nah, im sure it not one led, probably just one kind. i think the highest they make leds is like 3-5 watts. couldn't tell you abotu how good the light is though although i don't really see why it wouldn't work, except isnt part of photosynthesis also in the red spectrum?

i would just think if these worked well enough to grow pot nobody would bother with the giant halide setups you see on the news here and there

Thats what I figured too...the same company sells blue spectrum and red spectrum LED spotlights..I may get one and see how/if it works, but we'll see

if you do and they work let us know. it'd be interesting to know why not if they didn't

OK 2 things:
1. I've bought metal halide ballasts from that ebayer before. He does great business, the ballasts showed up super fast and they were $60 shipped. In the package, he threw in a free lighter with his company logo lol...Guess I didn't tell him the ballast was going to be used on a reef rather than-
2. A local hydroponics store had those LED lamps in, the overall consensus was that they were mostly just for entertainment purposes. Another way of thinking about it is that any LED system that can be concealed inside of a closed fixture like that isn't producing enough heat to worry about venting and thus isn't producing too much light since there's a nice linear relationship there... Furthermore the statement that the light produces the equivalent of a 400 watt halide is super duper rough math, and absolutely not true...notice he doesn't give any figure for the electricity used, I'm sure it's in the ballpark of ten watts....Furthermore again, that bulb is a single-spectrum bulb, and if you were going to keep it in a sump for growing macroalgae, you would have to supplement with some other source of light because nothing can grow under a single spectrum even if that spectrum is blue...
The end.
