Hi team, Last year, I made a DIY light for my 4x4 tent with 16 x CXB3590s and 4 x 200W, 1400mA dimmable drivers. I'm currently running it at about 750W at the wall and the plants and spider-mites are loving it Big thanks to Rollitup, @Growmau5 and @welight for inspiration and component knowledge. I now need to make another set of lights for an approximate 8x4 space, but I haven't kept up my research, except to hear that the CXB3590 may not still be the ducks guts for efficiency and set-up costs. I plan to go ahead in 2, 4x4 stages so I need to replicate the flexibility, power, spread and performance of my existing set-up and I'd like it to use less juice and cost me less money to build. Any Ideas?
