The panels are 16 watts apiece ( I'm using just a tiny bit more juice than one 60W light bulb, hahaa) not sure about the Lumen's. Apparently, from what I've read on these, they dont emit any unnecessary light that any chlorophyll plant needs. Take the green pary of the light spectrum. green plants dont absorb any of the green light spectrum because they are green. It just bounces back off of them. I do have a bit of the scientific information on these lights, but now a clue what it means, lol.
Blue LED light range - 430nm radiation peak athwart a 466nm emission range,
Red LED light range - 662nm radiation peak athwart a 680nm emission range,
