Why do new LED house light bulbs burn out so quickly in comparison to older house lighting types?   

Loring Chien , I know about light bulbs as electrical components

Answered March 24, 2018

Well they’re not supposed to. Under laboratory conditions LEDs will have a lifetime maybe 50 or 100 times that of a filament bulb. 👍

However, many LED bulbs underperform their predicted lives because they are allowed to get too hot. This is perhaps because they are installed in tight areas with no air circulation.

While old incandesents run very hot and dissipate a lot of power, paradoxically LED dissipate 1/5 the power but they cannot take heat like an incandescent. 📢 It shortens their life drastically. 👀

Another reason for LED underperforming lifespan-wise is that the circuit design is poor - using perhaps too cheap components that allow the supporting system circuits in the bulb last only a short time. Obviously a 100,000 hour LED paired with a 10,000 hour circuit cannot get the full 100,000 hours out of it.

Looking at the LEDs in my pantry, I have one brand that say 15,000 hours, one that says 11,000 hours and one that says 2000 hours. I think the latter only cost a buck though. Nonetheless, predicting these lifetimes is a difficult thing to calculate as well as to prove for the consumer.

Still incandescents typically were around 750-1000 hours lifetime.


Rob not the poor, because he is poor: neither oppress the afflicted in the gate:
For the Lord will plead their cause, and spoil the soul of those that spoiled them. Pr. 22:22-23
