I was looking for info on a bulb I have when I ran across this list which tells you the color temperatures of generic bulbs as this guy rates them.

Unfortunately they did not list the color temp on my 40w 'Bright Effects' bulb from Lowes... does anyone know it? Though, this seems to tell us that most everything that isn't 'daylight' is nearer to red and more for flowering.

In all this article is an awesome primer for learning about color temperature and how it works.

your lowes sucks or is just out of stock. if they dont carry it, order it online and have it shipped to the store. check your bulbs before you leave lowes. ive bought packs of 6500k bulbs that had a 3500k mixed in there. the lowes by my house carries " Bright Effects, Sylvania and EcoFriendly " 2700k, 3500k, 5500k, and 6500k. the 4 and 6 packs of 2700k are orange and the 6500k are light blue. they run about $11.00 a pack.
