I bought an LED light thinking I would replace my cmh . Not so.
Between the 2 fixtures my coverage area is excellent. With some ladies taller than others you can lower one instead of both.
Each have removable drivers and I mounted them outside the room to help with heat.
I spin my plants a few times a day. I don’t move the lights but the same idea..
I got in the habit when I had not-quite enough light coverage. I’ve added lights since, but I still rotate 2-3 x per day.
I added mine to room (5x3) when I first got it. One end Cmh the other Mars TSL2000. Didn‘t want to wait. Left drivers inside room. No dimming. They read about 145 degrees F after running all day. Lots of variables to that. I will move them outside the room for next batch.
