SUMMARY

LED bulbs age primarily due to factors such as thermal stress, electrical overstress, and material degradation. The estimated lifetime of an LED is often influenced by its operating conditions and the quality of its components. According to the discussion, understanding the failure modes of LEDs, as detailed in the Wikipedia articles on light-emitting diodes and their failure modes, is crucial for making informed purchasing decisions.

i'm shopping online for an LED bulb and one site gives the estimated lifetime of the LED.

So, i was wondering what exactly is happening to make the device "old" and no longer work?
