What causes LED light bulbs to burn out?

There is a reason that incandescent light bulb technology was dominate for over 100 years, and is still used in niche applications today. read more

If you don’t use a current-limiting resistor with a voltage source that is greater than the fixed forward voltage drop of the LED, a very large current will flow through the LED, causing it to burn. read more

Loose wires in the junction box of your light fixture (or in the fixture itself) can cause variations in voltage to your bulb. Basically, these variations act like miniature power surges that wear out incandescent, LED and CFL bulbs. Sometimes these loose connections can burn out your bulbs in a matter of days. read more

Another cause of bulbs burning out is excessive fixture vibration. A good example of this is a ceiling fan with a light fixture. When a fan blade becomes unbalanced, the fan starts to shake. This vibration jiggles the filament in the bulb and will lead to shorter bulb life. The same problem is common with light bulbs in garage door openers. read more
