I am wondering if anyone has used these bulbs before.. how good are they and so forth... i like the fact that you can change from 10k to 20k or even have 12k and 22k any combo you like... i need to get new lights soon just trying to find more user details... thanks
i don't have controllers
everything is manual for me old fashion. Plus my Ballast is a 500watt with 2 outlets i dont have a ballast for each bulb
