Incandescent Well Lights - How long should a lamp last?

Lamp life is based on an "average" life span of that particular lamp. A 2000 hour rated lamp may last only 20 hours…or it may last 6000 hours. There are many variables that influence lamp life. FX Luminaire purchases lamps from the highest quality lamp manufactures like GE, Sylvania, Phillips and Ushio, yet sometimes lamps burn out prematurely.
