I was taking a nap and just before I went to sleep, my room became dark. My metal halide went out. It's a sunlight supply model with an Ushio lamp, so it's not shoddy craftsmanship. I've only had it since the fall and I run it 16 hours per day. It gets hot, but not THAT hot.
I cut it off and let it cool down a little. Once it's cooled down I'll try it and hope it's not the ballast. For some reason I have to let it cool ALL the way down, otherwise if I turn it off and waiit 10 minutes it won't arc properly. Weird. Anyways I was wondering if it just got too hot or what? I'd hate to think it was a crappy ballast that blew. Assuming it just overheated, will this damage the bulb?
EDIT: It's working fine now. I guess it just over heated?
