Hey man whats up? Well im pretty much a newb to this as well so Ill tell ya what I can. I bought an advancedled 100 watt led, and only got it yesterday so it has only been on my plants for less than 24 hours, I could give you a better understanding of how well it perfroms. but so far so good. Its super bright, it has 3 watt chip diodes running the LED's instead of 1watts, which are a new improvement for more penetration. It's 11 light spectrum, 760nm, 740nm, 720nm, 660nm, 630nm, 615nm-480nm, 460nm, 440nm, 415nm, 380nm. These are the color temperature the light is putting out. The best ones I have been told are the 760, 660, and 440 I think, if you only get 3-5 colors, stick with ones closest to these numbers. Also, supplimenting your led with more cfl's or t5's are highly recommended. Im excited to see how it flowers on plants, check my journal for updates.
