As a sanity check hook it up to a 9V battery to see if it still works.

You're right Digit, it never dawned on me to suggest that, I took it for granted! Anytime I and the guys I work with buy LED bulbs we always connect them to an adjustable supply and gauge the brightness vs. voltage, sometimes adjusting the voltage lower than 14 will maintain the same brightness but drop the operating temperature of the LED array tremendously (we either rewire the LEDs or use one large resistor instead of a handful of 0805's like some bulbs get). Dropping the temps (by dropping voltage and decreasing power dissipated) really increases the lifetime of an LED. Most of the FleaBay LED bulbs are crap anyway, gotta rebuild them to get them to last.
