No I haven't bought it. I am researching for my intro into rdwc. I am going to grow 2 at a time in a 3'w x 6'h x 6'l box I am going to build. Michigan resident
Nice man, good luck.
Well, if you go for the CLW SolarXtreme 250, that will flower 1/3 of that space, about 6 square feet.
There are a lot of great options out there for LED. If you want to stick with COBs, Timber Grow Lights makes a quality light, and they are also a site sponsor here. Two of these lights will be more than enough light for your space, one light over each 3'x3' area.
This high powered 4 COB LED light fixture features Bridgelux Vero29 COBs and dual Meanwell drivers for maximum uptime. Remote driver placement helps with managing heat and custom color temperatures are available. Innovative design for use in a 3 x 3 to a 3.5 x 3.5 foot coverage area.

Otherwise, have you looked into boards and strips? If you decided to go the strip route, since there aren't many 3 foot strips out there, you could make something like 3 3'x2' fixtures with 2' strips. If you would like any specific recommendations, let me know.
Another viable option is ceramic metal halide. I don't know if you've ruled out HID, but 1 315 watt CMH over each 3'x3' area would also be a great choice. They will also add some heat into the space, which may be welcomed in winter and/or a cooler space.
