Amazon has these lights for $170 and I am just flipping to flower 4 autos and a photo. And so far it has been very good. The true watt draw is lower than normal because of the double chip. I started my plant's under it at 36 inches and they never reached at all. Very healthy looking plants under it. The 800 watt is smaller than my galaxy hydro 300's and has a good balance of color temperatures. Thought I'd give a heads up on these as they seem to be one heck of a deal. I'll update as I see the results of the flowering performance. I kinda took a chance on them because they are fairly new but very pleased so far.
Happy Growing
