I've seen a few failures, most of which seem to involve electronics.
A set of reflector spots (replacing 45W halogen bulbs) all in recessed ceiling fixutres in one specific location within the house failed within a few months of one another.
Another spot in the kitchen, in an exposed can, failed within a year or so. It was located directly over the sink.
I suspect moisture / condensation as issues in both, as the ceiling cans have minimal insulation between them and the roof, and the kitchen fitting would be exposed to steam / vapour coming off the sink.
Other than that, a couple of stick-style closet bulbs have failed, also apparently electronics. And one fixture in the garage which seems to have been physically struck.
That's over roughly a decade's experience and roughly 30 bulbs / fixtures. Far better than incandescent or even CF bulbs. Though still not quite meeting expectations.
- stephen_g 2y agoI have a bulb in my bathroom that I have had to replace every year or two. Meanwhile, in other rooms that I have renovated and I put good quality high-CRI LED downlights in, they're all still going strong after seven years. I think the biggest difference is that these downlights have separate driver modules and a short wire to the lamp itself, which must make the thermal aspect a lot easier to manage. This also puts the electronics up out of the condensation. The bulb in a regular socket in the bathroom on the other hand has the driver electronics there in the bulb, being heated by the lamps, so they're getting a lot hotter, and also it's there in the steam from the shower etc.
