High all. I know there are conversion bulbs to use HPS or MH lights with ballasts of both kinds. I have a 250w MH ballast and need to get a 250w HPS conversion bulb. Any input on the good ones? I was looking at this one. What do you guys think. Whoever points me to the right direction and what to look for, will receive rep. EYE 220W HPS Conversion Bulb - Plantlighting Hydroponics
