One of the problems is that while LEDs are more
efficient at producing
visible light than incandescents, and thus produce less heat at a given
light output, the heat produced by the LED isn't radiated, while much of
the heat produced by the incandescent is. This results in the LED
getting hotter than the incandescent bulb. While that heat doesn't
damage the incandescent, it is the primary failure mode of the LED.
There must be a way to engineer it so that the fixture to which the LED
"bulb" is attached acts as a heatsink for the LEDs.
