How Important Are Kalvins For Flowering

Now that I have my grow room (old bathroom) completely dismantled I am considering some changes before putting it back together. I have a Sunleaves hooded CFL with a 125W bulb @ 6100K. The hood really doesn't work well. I need it too high up to cover the plants in light. If I bring it down to an inch or two away, it only covers part of the crop (did I mention this is first grow). So I am rigging up something different with multiple clamp lights and was going to just put away the hooded light until I need it for something like seedlings/clones. I hate to store the light bulb, though, because I could really use the additional 125W.

Does it hurt to have a mix of CFL? One large bulb at 6100K and several smaller ones at 2700K for flowering?

Just a bump...I have my plants under mixed lights now.
