Yes, but how often to your usual light bulbs fail when they have been on for a while, they usually break when they are initially turned on. I wonder how these eventually fail.

Incandescent light bulbs are like old transistor tubes. LEDs are an actual electronic device and have similar qualities. If properly made they will easily last that long if not longer. IMO, LEDs will be the wave of the future. Lighting is responsible for a huge amount of energy use. LEDs use 1/10 the amount of energy than incandescent and florescent. My tip, save your money on the compact florescents and wait for LED lighting to be more affordable.

Like a candle; they dim gradually and sputter out.
