i think you are getting color temperature confused with lumens. color temperature is the color that the light is, more red, more blue.....and lumens is the measure of light intensity (as seen by the eye).

as far as color temp goes, you want 6500K for veg, and 2700K for flower, or a ratio therof.

you want as many lumens as possible.

what type of 10" fan do you plan on adding?
