They are serviceable in the sense that you simply replace them when they fail. Given that they cost so little now and have a service life of decades, it's more cost effective than a traditional fixture. Older fixtures with LEDs jammed into them were always an interim solution, and more prone to failure simply because of the design.

What do you mean? I’d much rather pay $30 for a separate LED driver and LED module that will last x0,000 hours and comes with a five year warranty instead of crappy LED lamps that last a few thousand hours.

Cooper makes the HALO RL series LED can retrofit modules that can be had for $30 with adjustable color temp and dimming capable, with a five-year warranty.
