Check out these links to documented grows going on with these led grow light panels:

I can't say they've made a perfect panel - for one, 11 bands is a slight waste, IMHO, at least by my research. I've tested the entire visible range and measured photosynthetic rates by observing the amount of O2 production. There are only 5 particular wavelengths that should be paid attention to, at least according to my research, and in reality only three of those really need to be the primary ones.

These are looking good. Going to have to see if they're going to match my custom-designed panels which should be in just in time for me to run a starting flower cycle. I have 6 Hindu Skunk clones under 20W 70:30 R:B dual-band LED. One is a runt, but it doesn't matter, I only asked for 5 from my old progeny, so six is a gift. The two in the custom multi-site bucket in the back right will be transplanted into an old PC case that I have completely sealed except for airflow (no carbon filter, legal patient, no need to worry, even the management knows,) and lined with Chromalux paper (Too lazy to futz with foil or mylar, just cut this stuff and glue it in, done, hardly a crease, just a few bumps.) I'll be putting in a 60:40 red:blue tri-band panel in the top of the PC case. The two in the black professional buckets are going to become mothers. The white Krusty bucket will be vegging constantly for a while, trained, and eventually put under a 120w panel of the same configuration. I've got two lines of lights - I have a vegetative purposed line (which has worked awesomely for all of my plants) in low wattages, and I have a bloom line in the higher wattage range. This is to help deliver even more efficiency.





Also, we haven't seen g/kWh or g/W numbers, yet, these are not finished grows. Until I see those, I'll have some reservations. I only have a couple of problems getting 1.5g/w in 12/12 from clone SoG with my admittedly absolutely-crappy 50:50 dual-band penetrator bar (high-focus lower power LEDs for deeper penetration, not for area coverage) but I have managed to do it and the bar is only 16W.
