Does High Lumen Affect The Service Life Of Light Sources?

The lumen value itself does not directly determine the service life of industrial light sources. However, it is directly related to key life-influencing factors such as light source power and heat dissipation design, thus indirectly affecting the service life.

The specific correlation logic is as follows:

High lumens are usually accompanied by high power and high heat generation: To achieve higher lumens (total light output), industrial light sources often need to increase power (e.g., increasing the number of LED chips, raising the driving current). Higher power will lead to increased heat generation inside the light source (such as LED chips and driving circuits).

Overheating is a core factor shortening service life: Most industrial light sources (such as LEDs and tungsten-halogen lamps) are sensitive to temperature. Long-term high temperatures will accelerate the aging of internal components (e.g., light decay of LEDs, failure of capacitors in driving circuits), leading to premature damage of the light source or "light decay" (the lumen value decreases with usage time, and the light source can no longer meet usage requirements even if it is not physically damaged).

Reasonable design can offset part of the impact: If a high-lumen light source is equipped with an efficient heat dissipation structure (such as a metal heat dissipation shell, active fan cooling), it can dissipate heat in a timely manner, and its service life can be close to or even equal to that of same-type low-lumen and low-power light sources. On the contrary, if a low-lumen light source has defects in heat dissipation design, its service life may also be shortened due to local overheating
