LED Lifetime & Reliability
Long life has been billed as a key advantage of LEDs, but understanding and communicating how LED products fail and how long they last can be challenging. While LED-based products hold the potential to achieve lifetimes that meet or exceed their traditional counterparts, manufacturer claims can be misconstrued by endusers who do not fully understand LED product failure mechanisms or the difference between lifetime and reliability.
The DOE has released its latest in a series of fact-sheets which explains how LED products fail and how to compare various manufacturers data sheets and performance figures.
The fact-sheets are available to download for free from the DOE website.
