The LEDs themselves are very robust, solid-state semiconductors that will function for a very long time, but they need additional electronics to function in a 110/220V socket, and those electronics seem to be crummier than the old incandescent filaments.
- nikau 4y agoYep - I've done a post mortem on a few LED bulbs that failed and each time the LEDs were fine but the driver failed. This is anecdotal, but I had a bunch of bulbs of the same brand that started to fail, on the remaining bulbs I drilled a few air vent holes into them as they are used indoors only, and since then haven't had another failure. I'm suspecting most LED bulbs fail from thermal stress on the driver circuitry.
