Run of the mill LED light bulbs... suck!
No really, despite claims of "50,000 hours of life", already I have 7 of them "burn out" within 4 years.
To be fair, it is the mfg using the cheapest parts out there. And what is probably the case (have not tried) is the LED still works, but the voltage regulator (VR, changes the 100v to 240v AC to about 6v DC) or capacitor fail (but 1 of them did look like LED itself failed).
So, I had 3 Ikea bulbs fail (400 lumins, $1 each), not surprised about that.
However I did have 2 Sylvania Osram fail with explosive results (cap blew), which surprise me. I also had a Lowes brand "Utilitech" fail party (lost brightness, I think 1 LED element went out). I have one other can't remember what it was.
I also use a few Wal-Mart brands, and they buzz like an angry fly (VR).
How do I know? I wrote the date on every LED before I installed.
The reason why so many fail is probably also quite simple, the heat sink.
LED's produce heat, but do not have the mass to take that heat, thus a block of metal is used to draw the heat away from the LED, and the VR.
That "Utilitech"LED weighs 93 grams. The same type GE model weighs 140g, very likely there is a 40g piece of aluminum as heat sink.
So far all my GE ones work fine, and are the oldest I have (7 years). They were expensive (up to $15 each when I started). Sure it will pay for itself in a year or 2, but that is a lot of money to change all the bulbs in house (did a few at a time).
As it happens I work on a machine that uses high powered LEDs and back in 2007 we discovered the limitations of LED, but over years saw the price plummet and quality improve (and improved our tech too). Today it is not difficult to make a high lumen long lasting LED light bulb for <$5, likely <$1 if made in low wage countries in Asia.
So, yes, I am ranting the promise of much longer life of LED over than CFL and even Incandescent bulbs is almost a lie. There should be an actual life span on the entire bulb, not a theoretical of just the LED.
For that lie LED bulbs (currently) suck.
