I am doing a comparison grow using 3 different types of LED lights in case you are interested in checking something like that out > https://www.rollitup.org/grow-journals/474084-ultimate-led-test-glh-spectra.html
YOu missed one, black dog led, would have won your competition hands down. 15 spectrums with uv/ir, 3w led's running over 2 watts each and 5watt led models for 2011.
