none of the above in the place where I live (remote region of the ocean) these were the best I could find at the hardware store. they were the highest lumens I can use with my set up.Go to any store, walmart, Home Depot, Lowes, or any store that sells CFL's, and pick up some Warm white CFLs. They should be around 2700k color temperature. That will be fine for flowering, but you might want to bulk up on more lights if you want to yield anything significant.
