In my opinion, those low power units are for showing off some house plants, nothing more. Building a unit with the high power LED's takes some skill. I am an electronics tech, and built my system from the ground up. I do want to increase my power output to the next level, and increase the bandwith both into the deep red 660nm, and a few in the ultra violet if I can find the right power and price. Point is, if you want results from an LED system you have to think in power. It would take at least 300 watts of the right LED's to start to come close to a 1000 watt HPS/MH combo light. I found the ultra bright high power LED's penetrate right to the bottom of a two foot canopie
