My son is a complete gear junky. He camps quite a bit and has an amazing eye for quality stuff.
A few years ago he gave me a set of these:

I have other, cheaper headlamps I put in every car, unopened, for emergencies, but the Moon Sport is really, really good and my go to.
It has a UBS re charger and is always ready.
For non airline trips I pack it in my suitcase just in case. The only issue is they are made in the PRC.
For other flashlights, I have a bunch of run of the mill, waterproof stuff that I rotate, Nothing special.
