It's not printed on the bulb unfortunately but it was like $7-$8 at walmart. I suspect it's not the leds that failed but the regulating electronics - I'm saving it to try to re-use the leds someday, maybe for direct-drive off a battery.

The $15 one above looks like much better quality and 1/3rd the price of the philips. I'm not dropping $40 ever on a led bulb.
