Transitioning to LED lighting can result in long-term financial savings. What is the status of lumen depreciation? Investigate lumen decay and its implications for your LED lighting.

Lumen Depreciation Streamlined

Light Emitting Diodes (LEDs) represent a significant advancement above conventional fluorescent or metal halide lighting. Transitioning to LED lighting can result in significant long-term financial savings. What is the status of lumen depreciation? If this word is unfamiliar, continue reading to learn more about lumen depreciation and gain a deeper understanding of your LED lighting.
 

What is lumen depreciation?

Although it is widely recognized that LED lights possess a far longer lifespan than fluorescent or metal halide bulbs, it remains a reality that no light bulb is everlasting. In contrast to conventional lighting, LEDs do not abruptly cease functioning, hence preventing total darkness. Conversely, LEDs progressively diminish their lumen output during their lives. Let us analyze this in detail.
"Lumens" are the units employed to quantify the brightness of a light source. A higher lumen output results in increased brightness.
Upon first installation, an LED light outputs "initial lumens," which refers to the light output produced immediately after stabilization, prior to any depreciation. This is the point at which the LED exhibits its maximum brightness and output.
The luminous output of the LED diminishes with time. This procedure is referred to as "depreciation."
Lumen depreciation may be computed at every moment via a rather straightforward calculation. Divide the LED's lumen output at each given moment ("mean lumens") by the LED's initial lumen output. The outcome of this equation will be a decimal. A ratio of 0.8 indicates that the LED operates at 80% of its original capability.
At what juncture is an LED bulb deemed "failed" or necessitating replacement?
The widely acknowledged guideline for replacing LED bulbs is when they emit 70% or less of their original lumen output. This temporal reference is termed the "lumen maintenance lifetime," often known as L70. The longevity of an LED light is quantified in hours. L7o is the duration of illumination an LED delivers before its output diminishes to 70% of its starting level.
