As we all know, a good LED could last very long up to 50,000 hours with with a good heat sink. But how is the LED driver electronics life? For common LED drivers there is at least one component is very weak. It’s the electrolytic capacitor.
High Bay LED Lighting Driver Heat Dissipation Temperature Test Report article gives some use useful information related to electrolytic capacitor life.
Typical temperatures for the how electrolytic caps are 85°C and 105°C. Usually the life time is 2000 or 3000 hrs at one of the above temperatures. This is how electrolytic caps are specified. But the cap’s life doubles for every 10°C below that temperature. So if you go 40°C below the specified temperature, you gain a factor of 2^4 = 16. 16× 3000 hours = 48,000 hours.
If your LED driver has caps at temperature 80 °C, the LED driver only can last about 2 years or less. After that time you can expect poor performance (lowered capacitance, increased ESR) or even capacitor exploding.
