Cloning, saving power around the house when your HPS arrives.
PITA when there is a few of them swinging around.
It's worth having a few in stock.
My 18w are 1200 lumens, and some 400w are 55kl. That's 46 bulbs to replace the HPS, using 828 watts.
Can you tell me the name of the bulb? I haven't seen a 20w compact with that many lumens. |
