You gotta realize that HPS has the best efficiency. For 400W youâ??ll get about 50 000 lumens. VS a 400W CFL Iâ??m guessing would be like 24000 Lumens.

So if you only want that much light go with a 250W hps save on the bill.
harris7 Reviewed by harris7 on . Amount of CFL vs Higher Wattage. Is it worth it to drop the extra money on the big CFLS (105-125 watt 30-50$ a light) Or use multiple low wattage? What do you guys with experience think, because I'm considering using all CFLs to save money but still would like to attempt a sea of green grow in a 4X4 organic soil bed (for 16 clone SOG). Rating: 5
