Hi there foe did you check out the cfl tutorial here is the link CFL Tutorial

It has all the info on lumens there.

5500k!!!!!!!

higher kelvin temperature rating are associated with better and bushier vegatative growth.

Yea I read it but got confused. I no about kelvin but what I got from the article was that more lumens was more beneficial. That is where I got stumped. Being where my flowering cfl's have way more lumens(5400) I thought it would be more productive than the 2800 my day light bulbs put out.

kelvin is a measure of the shade of light or the wavelength ie warm red or cool white

lumens are the intesity of the light

you want just about as many lumen as possible but folk prefer the lower kelvin for flower the higher kelvin for veg....and some use a mix

I hope that helps but repost if its not clear enough
