A Closer Look At The LED Lifespan

LED Lifespan

LEDs come with extended lifespans of up to 50,000+ hours. Compared to other lighting technologies, the units can keep an area illuminated around 3-4 times longer! Incandescent bulbs last roughly 1,000 hours, while compact fluorescents have a lifespan of 10,000+ hours.

For industrial sectors, metal halide lamps last around 25,000+ hours – but require meticulous maintenance during their lifetime. LEDs not only stay on longer, they can also withstand rough treatment and extreme environments, due to their solid-state designs.

No Burn Outs

Unlike conventional lighting systems, LEDs do not burn out at the end of their lifespan. Instead, they slowly lose their lumen output levels, resulting in dim lighting. During this period, supplementary illumination is needed to keep the target area well lit. This process is advantageous for busy locations, because the shift in brightness serves as a warning that the luminaries may soon need to be replaced. Other types of lights that completely burn out at the end of their lifespan would require employees to stop working, as it would be too dark to complete tasks effectively.

To reach 50,000 hours of use, you would have keep the LED light on for 10 hours a day, for 13.7 years. At a rate of 8 hours per day, LED fixtures will last around 20 years.

Deciphering LED Lifespans

The LED Lifespan can be rated at 70,000+ or 100,000+ hours. These thresholds do not necessarily equate to the light’s capacity to offer 100 percent illumination. In most cases, an LED lamp is rated up to 30 percent lumen depreciation. With this in mind, an LED bulb with a lifespan rating of 100,000+ hours will offer 100 percent illumination up to 70,000+ hours. After it has crossed this milestone, it will provide depreciated lumen output. However, the lamp is still usable.

For LED spotlights, this characteristic is important to factor in. A decrease in lumen output will result in a weaker beam with limited reach.
