Comments about Universal 1000 Watt, 120-277&480 Volt Metal Halide Ballast:
I have replaced 10 Mercury Vapor/ HPS ballasts with these and the light quality is great almost complete fixture for the price of a mercury vapor bulb. They can start up kind of loud but in 15 minutes they are bright and quit
Bottom Line Yes, I would recommend this to a friend
