led post lights: Why do light bulbs burn out?

I assume we’re talking the led light bulbs here . This questions we should devide by time to see the reason :

If you just receive the lamps and found it burn out : The reason is express / Delivery .
If you just finish the installing of the lamp and found it burn out : Pls check wether you install according to the instruction file ? 95% led lamps before install must remove the ballast / capacitor /ignitor .
If you did remove the ballast / capacitor /ignitor , pls check wether your wire connection is loosen .
Normally people will check the application Voltage before install as well , so make sure the led lamp input voltage is meet your contry standard voltage .
If your lamps use over 3 months and start failed , Mostly is Driver Failed . Surge is a big headache problem for Varistor .
If your lamp is not wateproof , but you use in wet location , then will failed .

Normally if the driver material is build of Rubycon Capacitor or some Japan/ USA/ Korean Material , then quality is stable.

The Market stable quality driver is : Meanwelll , Inventronics, MOSO etc .

I have experience in led lamps for over 6 years . If you have any request or any other questions feel free let me know .
