Ive got the 400w 12k reeflux. Im super impressed. I went from 20k radiums. The reeflux still have a nice blue tint to them, but still much whiter then the 20ks. Get pretty good reviews from what I've read as well.
I really liked the radiums. Im a blue fan
I just needed something to give me better growth. The 12k reeflux is a perfect compromise for me.
