No no no, it's cheaper to run. 2 DE running at 1150w each, 3lb per light. 6 pounds for 2300w. I can't get that with SE by any means. Well, close, with the right strain. I've got 2.7lb on one SE light. Like once lol. But with good healthy clones and no screw ups, running SE 1000w, I average 2ish per light. But it's been a while since I got that even because of sick cuts or random issues happening, so with different cuts I've been running I'm happy with 1.5lb per light or even 1.25 per light for that matter.
