Have you tried replacing the LEDs or have you just assumed it's impossible because it's not a bulb?

I know how to solder tiny parts and big parts, and I'm actually pretty good at it. I can generally take complex things apart non-destructively and reassemble them without damage. I can use a meter. I understand how electronic components work, and I even find pleasure in using them. I can safely troubleshoot and repair or replace a power supply.

Fixing an LED fixture is within my wheelhouse. I can repair them.

I just don't want to.

It seems like a much better use of my time and money to just screw in a different light bulb and forget about it.

It depends on the specific fixture.

But then, the problem is, it depends on the specific fixture. They aren't exactly putting "EASY TO REPLACE LEDS" on the box. I can't climb up to the store display model and start hacking away at it to see if I can get to the LEDs, replace them, and reassemble it correctly.

What I saw last time I was in a store where the fixtures were on eye level looked like a lot of glue, one-way tabs, and LED strips of unknown and custom provenance were being used. I'm not really looking for this sort of experience in a lighting fixture. YMMV and more power to you.
