where are these made?

DO NOT BUY THESE. I've gone through THREE bulbs so far. On the HI power setting, they burned out after 4 hours of usage (average). Low power (100w-ish?) probably last little more than a week. These bulbs were made in China, so you get what you pay for.

anyone the the efficacy of these bulbs (lumens/watt)?

This bulb has a power of 250 watts and a brightness of 4,500 Lumens.
