I ve only had my Hamilton fixture up and running for about 3 months and one of my 250 halide bulbs blew out already with no warning at all.:bawling: its an HQI type. 3 months seems a bit early for a bulb to go. the halides are only on for about 6 hrs a day. Do ya think hamilton will send me a bulb? They alredy had to send me a replacement fan for the same fixture because one of them was defective.
