LED Lighting

Light Emitting Diodes

The light emitting diode (LED) is part of a family of lighting technologies called solid-state lighting. LED lighting is a rapidly evolving technology that has the potential to revolutionize the lighting industry over the next decade. It is already beginning to surpass the quality and efficiency of existing technologies however, not all LED lighting is created equal.

LED lamps are more rugged and damage-resistant than compact fluorescent lamps (CFL) and incandescent lamps. LEDs don’t flicker and don’t require a warm-up time; they also have eco-friendly characteristics since they don’t emit ultraviolet (UV) radiation.

The useful life of LED lamps is about 35,000 hours compared to 1,000 hours for an incandescent lamp. The lifetime for LEDs is a matter of the overall system reliability that includes the LED lamp, the ballast or driver, electrical connections, the housing and lenses. The key to long lamp life is thermal management; the LED must be kept cool. Since LED lighting is a rapidly developing technology, many products have not been on the market long enough for the lifetime claim to be put to the test.
