A lot of
led manufactures make outrageous claims about their
lights. It puts LEDs in a bad light all together and it's a shame because used correctly you really can get great results from LEDs. A 45W panel is just bearly enough light to grow 1 pepper plant and actually get peppers. For a 4x4 grow space I have found 4 UFOs (360W) to be the ideal amount of lights. I have grown strawberries, cucubmers, cherry tomatoes, all sorts of peppers, and many more things with this setup.
