I'm running magnetic ballasts with 250W HQI bulbs. I like the blueish white light. I don't like the black light look of some 20K, or the ugly 10K. Something in between. What bulb would fit my needs and work well on magnetic ballasts?
Thanks
EC

I've never used a 15K bulb, but I've heard they are low in PAR. I run 14K now. Two different brands. One of them looks pretty good. the other is ugly as sin, and looks more like a yellow 10K.

I run the SE reeflux 12k bulb but i have seen the DE version used and they give off a really nice bluish-white color and give you really good growth as well.
