Well you would see a difference in your power bill if you went
with what UPS suggested.
When i had a larger room I used MH's and Hps's wish i would have
known about these CFL's then. Hell did they even have those in 95?
yabatab Reviewed by yabatab on . Lumens CFL/HPS I've always used single or multiples of 400watt HPS lights for a 3'X3' canopy,this gives me around 5555 lumens sf... my question is whats the differents between the 400W giving 5555 and say a 85W CFL giving 5500 over the same sf? besides needing 9CFL's to cover the same area..
