Why can't the heat sensitive components be designed to cope better?

LEDs do not produce heat so that is not a failure mechanism. Mechanical
failure is most likely and I have a new totally enclosed and waterproof
LED lantern which quotes 50000 hours typical life. Not seen the tubes
but the construction must be similar to other LED luminaries with LEDs
spread along the length of the tube. I would expect similar service life.
