Generic CFL types and their color temps

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.
