alright, thanks that does help.. i think, provided i just found the right specs.
i found the GE site that has the color temps, but all the product codes are slightly different than what i see listed on the bulbs (ex. my cool white is just called F40CW whereas the closest on the site is F40CW/ECO/CVG), so i'm still a little skeptical.

this is the spec site:
89714 - Lighting System Specifications - GE Commercial Lighting Products

and these are the printing on the bulbs

:wtf:

oh and probably a dumb question but:
are the colors one sees emitted by the bulb the color the plant absorbs, i.e if you have a red bulb is it gonna send out more red wavelengths?
for instance wide spectrum is purple-ish, so does it send a lot of red/blue?
kitchen/bath is orange, and the residential/cool white are about the same
Miroku12 Reviewed by Miroku12 on . fluros, which bulb is better? i understand about cfls, and hps/mh bulbs being better, but i'm going down the cheap route to headsmoke. right now i'm growing 3 plants, just for future personal use ideally. they're only a week in, so still veg. i have them in a very small white closet with 2 4ft fluros above, and just for giggles a "spot-gro" bulb hanging above that, sending off a bit of bluish light to add to the fun. i found a mass of bulbs out in my fathers workshop i can use, but i'm not sure what the best combinations Rating: 5
