I've got a few bathroom light fixtures that seem to be real bulb killers! I expected these LED bulbs to last around 10 years, but they only last about 6 months to a year. I suspect it's because the fixtures are older and might not be suitable for LEDs, potentially causing them to overheat. Before I dive into replacing the whole fixture, are there other factors or tests I should consider first?

Considering the fixture design is important! Cheap ceiling fixtures or those without proper ventilation tend to 'eat' LED bulbs quickly because heat from the driver board builds up. If you haven't already, try out different brands of bulbs to see if you can find a better match, as some just work better with certain fixtures.
The condition of the light fixture could really make a difference. If it's a closed or poorly ventilated space, that can create a mini oven effect, which is not good for any bulb. I had a similar issue until I switched to a brand-name bulb that was rated for my specific fixture—it solved my problems!
Make sure you're using the right types of bulbs for your fixtures. Only use non-dimmable LEDs in non-dimmable fixtures, and vice versa. Also, if there's any steam (like in a bathroom), you should be using wet-rated bulbs. If your fixtures are fully enclosed, try leaving some air gap for ventilation—because even if the bulbs aren't super hot, the base can get pretty warm and that heat buildup can lead to burnout.
