Hi y'all - been reading the forum for a while, but this is my first post. I'm a Peace Corps volunteer in west Africa at the moment, and CPF helped me choose a ZL H51 and a Fenix LD20 R4 - couldn't be happier with both of them - thanks folks! Living in a thatch roof mud hut in the bush gives me a lot of opportunity to use them too, which is highly satisfying. I have solar power and internet (weird, right?), but in general the village is a very dark place at night.
Anyway, I want to run with the H51, and the stock band/silicon doohickey isn't doing it for me. I scavanged the top strap from the old Princeton Tec headlamp the ZL replaced, and it happened to fit perfectly. The sewn loop on one end of the band was just big enough to slip over the end of the H51, and the width of the strap fits exactly between the two silicon loops. The fit of the strap loop and the silicon holder together is pretty tight, eliminating accidental rotation, but allowing intentional rotation with a little effort. I cut the sewn loop on the other end of the strap, and threaded it through the buckle originally used for tightening the top strap.
The setup is super solid, and makes this headlamp as directionally stable as any other headlamp I've used. I haven't run with it yet, but I jumped around a bit and it seems very effective. I hope to run with it tonight, though most of the trails here are rivers now during the rainy season - maybe I'll get to test the waterproofness too
