What's the specs on the LEDs? How many watts/diode, refraction angle of the light lens, color spectrum and ratio?

There is a TON of misinformation out there in regards to LEDs. You can grow with them, but you must have high quality diodes, a focused lens (i.e. 60 degrees), and proper distribution of red and blue spectrum. Good LEDs aren't cheap (although they pay for themselves in the long run). Most of the stuff being peddled isn't much more than Xmas lights in a box.

If you are running two grow rooms (veg & flower) consider using the LED for the veg cycle and get something a bit more robust for flower, either LED or HPS. And don't believe everything those marketer write!
