I have one 315w cdn/lec and a couple of cobs plus a couple each of 600w & 400w hps and am really happy with the 315w and a 55w cob either side of the 315w in a 3x3 ft tent. But… my bulb on my 315w has died ( warranty issue), so atm I’m using a 400w hps and my cobs ( got a few auto’s filling the tent, I’d say temps are about the same for a 315w lec and a 400 hps ( metal halide burning bright)… good lights for this footprint or get a 630 DE model for bigger areas…
Hope this helps some @dweaver864.
Happy growing
