There's a Philips LED (one of the weird looking three-lobed ones) that has been burning continuously in the entryway of my inlaws' house for over seven years. It's a 60W equivalent. I bought it for them because a) the light burns all the time (even in daylight that area is dark) and b) it's a pain in the butt to change.

I think it was about $45 when I bought it. A similar model is down to $21 for a 100W equivalent now.

I've got several other Philips bulbs of that type that have been in use for a long time, though not quite that long.

I've never had one go out.

As with you, I've had numerous cheapies go out over the same interval.

That sounds like the bulb that Philips won the L Prize with:

Yep, that's the one.

It produces good-quality light, too, despite what you'd think from the yellow shell color.

Yes. I bought some very cheap LEDs of AliExpresss, but they failed quite quickly (no surprise). Name brand bulbs from my local supermarket have, so far, held up vastly better.

One of the more amusing ways the cheap bulbs failed is by neglecting to use UV stabilisers, so just leaving the bulb on would cause them to degrade their own housing until they fell apart. (The other main failure mode I saw was the transformers giving out.)
