About two years ago I purchased a number of Cree 60 watt LED bulbs. I was impressed by the build quality and light quality of the bulbs. These bulbs were touted as lasting 15-20 years. I write the current date on the bulb when I install one. In my experience these bulbs have been lasting about 2-3 years. I don't think the LED itself fails, I think it is the power supply integrated into the bulb. Cree customer service has been great, I can just return the bulbs for a replacement at any Home Depot.

Most consist of just a bridge rectifier and capacitive dropper, some of which are so bad as to negate some of the advantages of the LED's efficiency. Poor design and cheap components are the norm, so you get lots of failed diodes and capacitors. They also have terrible power factor, though that isn't much of a concern for consumers.
- jpeg_hero 10y agoYep, similar experience here with my first led lightbulb (Phillips). I wrote the date on the bulb fully expecting to laugh when I had to throw it out 20-30 years hence. You know the punchline-> dead in two years :(
