On fluorescents, what is the CRI number for? I heard the higher the better, but sometimes they seem inverse of the color temp.

Sorry for all the newbie type questions.

I have an article I wrote on CRI in my blog along with some other information on fluorescent tubes which may be of some help to you:

We also talk about our bulbs, how they were tested and posted test reports on them here:
