No, it is now 4000 lumens.
IF the bulbs are very close together and light the same area.
If they are far apart and do not light the same area, you now have 2 areas at 2000 lumens EACH.
stinkyattic Reviewed by stinkyattic on . Does 2 bulbs @ 2000 lumans each...... give me total lumans of 4000? Or does it stay at 2000 regardless of the number of bulbs? Maybe a silly question, but I have read KP's Cannabis College and I still don't have an understanding. Thanks guys, Randy Rating: 5
