well with more light you get more of a even band of it over the plants vs. a single light.

however the single light has a better penetration to the canopy then the other CFl's

if it where me i just get 4-42watt CFLs at walmart and use them instead
invision Reviewed by invision on . CFL's vs 1 CFL?!?!?! I have a quick question...i have a choice of getting either A. (1)-105watt 6000k = 6900 lumens or B. (4)-23watt 6000k = 6400 lumens (1)-9watt 6000k = 520 lumens = 101 watts = 6920 lumens Which one would you choose? Thanks! Rating: 5
