CFL Question

I am very close to starting my first grow. Box should be done this week. I have planed from the start to use CFL do to heat issues. Stumbling around at a 99cent store looking for a few items I ran across 24w CFL that are 2800k, Is it a major different in the normal 2700k used for flowering. I picked up 24 of the bulbs not so much for the grow box but for general use around the house. I could not find the kelvin rating on them at the time. Then this afternoon I was sticking on in a light fixture and looked on the bottom of the box and it stated 2800k. Yes I am hoping the difference will not make much of a difference.
