I was surprised to see these in the "blue" DIY store yesterday. Lifetime is stated as 15,000 hours which seems a little short to me. I'm guessing they're driving the filaments pretty hard. Has anyone tried one yet? I thought about picking one up but I was hesitant about buying a 15,000 hour lamp for $40. A quick search tells me that typical metal halide lifetimes are in the 6000-11,000 hour range.
