I bought a dynamo-powered keychain flashlight at a museum gift shop for a few dollars, in 2013, for my PSK. I'm currently updating my PSK. I still like the idea of a dynamo-generator powered flashlight for reliability, but I imagine there must be better ones than this, since this one is already "ancient" in terms of LED technology, and since this one was dirt-cheap to begin with. What is the best one available, as far as you know? I'm interested in features like brightness, efficiency, waterproofness, shockproofness, etc. I'm asking specifically about keychain type ones that are small, like a box of matches (small enough to easily fit in a PSK), not asking here about full-sized flashlights.
