Never had issues By Raul Badillo on 3/14/13Raul Badillo would recommend this product to a friendSteve, I think you just got a bad batch or just coincidence. I have the 10ks, for the record, best par bulb out there, also, going on 3rd set in 3 years, never a burn out........
I would avoid hese bulbs! By Steve on 10/20/12Steve wouldn't recommend this product to a friendI put two of these 250w 10K bulbs over my 120 gallon reef. I liked the bright white light, but both bulbs burnt out within one week. One bulb lasted two days and the other bulb lasted 5 days...what a waste.
I am using two 250 watt Galaxy ballasts.
