Life cycle (h)
The main characteristic for semiconductor-illuminants (LEDs) is their long life expectancy — as long as they are operated under very special condition. Unlike ordinary bulbs LEDs do nut suddenly fail, but gradually lose brightness during the course of their lifetime. Depending on the quality of the light-emitting diode this degradation may happen faster or slower.
