FYI, Osram is a zombie brand these days. The company was broken up and the consumer lighting brand was sold to some Chinese company that is selling some stuff branded with it.

I've had LED bulbs that lasted for well over a decade. Most seem to be pretty indestructible. But I've got one rail-mounted system using GU-5.3 leds that all seem to die pretty quickly. Not sure what's going on there.
