litespeed Reviewed by litespeed on . Free lights!!! Ok, now that I have your attention . . . I have an opportunity to pick up some MH ballasts and base/socket assemlies from our old warehouse at work. They still work fine, just updated to high output flouro in that part of the building. The ballasts are all 400W Metal Halide, with a 220V hookup. Can these easily be converted to 120, and will a several year old ballast be worth it? The key motivator here is that they are free. Questions comments and snyde remarks welcome. Rating: 5
