looking for some opinions on 250w MH bulbs. as of now i have a 10k reeflux and some piece of crap plusrite 20k. when i built my 65g i only had one, but now have a galaxy dual ballast. time to get the color right. i know the radiums look good in the 20k but have seen some bad reviews on people getting the bulbs in bad shape with terrible customer service. anyone running the xm 20k's or im open to any other brands. thanks
