Zebra lights still kicking

These have been the best headlamps, going on 8 years now. My wife doesn’t use hers as much, although it has survived two trips through the washing machine lol, but mine has been through 3 headbands and I’m due for the fourth, not much elasticity left. We built off grid and so these lights were pretty much our only light for the first five years, and I have my own business doing construction so my headlamp gets used basically daily there too. Some solid lights, that’s all I’ve gotta say they haven’t missed a beat, I’ve used mine down past 0f and well past 100f in attics. I’m curious at this point just how long they will go.
