i just went out and got myself a 2 foot double fluro fixture and it came with 2 18 w power saving tri phoshure bulbs that are rated at 4000K, Can anyone tell me approx how many lumes these will put out.... Anyway, hopefully the ladies like it. i plan on putting the cfl's that i have around the plants for a little better light toward the bottom of the plant, as the first time i wired it up and pluged it in i noticed that not as much light is getting past the canopy
