Lightbulbs are a bad form factor. I have some lights without bulbs and no issue. Meanwhile the halogen emulating LEDs break all the time.

Exactly. Luckily halogens were commonly installed in pots. So for longevity, replace the pot rather than the bulb.

It usually comes down to the brand, factors you can't be aware of like component choice, and the light fixture itself. A lot of LED edison socket lights die quickly in recessed lighting or other tight fixtures because the heat is death to them. Manufacturers build the worst technically functional capacitors into the power supplies with a low temperature rating, meaning they really can't handle anything above ambient.

This is also the same industry and the same players that were perfectly fine with agreeing to not improve incandescent light past 1000 lifetime hours, illegally. I have no doubt that there is a tacit agreement not to make good lighting, as that would extremely disrupt the industry.

I'm repeating myself a lot in this thread, so I'm sorry. What fixtures are the bulbs in? Are they a generic design meant for incandescents? A huge number of fixtures out there don't allow for enough heat to convect away and the bulbs overheat.
