I've got this light set up in my 3x3 tent, primarily for vegging, and it's been phenomenal. Even at full power with just an exhaust fan and no AC, my temperatures never exceeded 81 degrees. It's absolutely perfect for tent and closet grows. Bravo to the team behind this fantastic light!

Hot lights but great product so far. Plants are loving it now that I have the AC unit

Plants are loving it now that I have the AC unit, iv had to re purchase an 8inch exhaust cuz the 4 wasn’t pushing the heat out. Re bought a 8inch isolating fan to replace my 4 inch. I purchased a portable AC unit for the room that’s average 71 at night 77 in the day in the tent 81 too 95/105 with Exhaust is exiting the room.

Now with the new Exhaust, fan, and Ac unit. Room temp is 72 with the tent temp at 81 average in the day
