If the light is unsecured and clunking around, is that not just because you haven’t fitted the headstrap properly? Silly

Have you used a headlamp before? The straps are elastic and there will be movement unless you stretch them uncomfortably tight.

In my opinion, this shouldn’t happen with a well-designed headlamp, even an 18650 or 21700. I don’t have experience with the budget brands, but Petzl, Black Diamond, Zebralight H600’s & even Olight’s heavier 18650 right angles are secure enough for big, jerky climbing movements and unexpected 15+ ft whips into rock slabs.

I’m sure something like a Perun 2 or PL47 would be more comfortable and secure strapped to a helmet for that kind of movement. I probably wouldn’t use something that size for running, but I wear the H600 often without a helmet while climbing, and it’s perfectly comfortable. I cannot imagine the weight difference between a 21700 ZL & 18650 ZL being significant enough to make a difference, but that’s probably a testament to ZL’s design.

It all comes down to preference and use case, and mine doesn’t seem to be very representative of the BLF forum. For most people, using a smaller light and swapping batteries is probably ideal, like when camping, hiking or jogging. But in certain scenarios, a battery swap can be temporarily impossible or even dangerous. I know I’m being really specific to my own use, which probably seems niche here, but I’m sure it’s applicable for canyoneering, caving, SAR, etc.

I mentioned it in LoneOcean’s X1 thread, but I’d really like to see a Noctigon, FireFlies or Lumintop right angle with the new X1 driver and single emitter. Replicating ZL’s size, weight, durability and thermal efficiency would be unrealistic, but something even close with Anduril would be awesome.

Got a Perun, Mini and LD15R all with headbands. None of mine bounce and clunk around. I also have several other more industrial models that we get issued for work, which are primarily for helmet mounting but also come with pretty solid headbands.
Yes, if you actually reach your hand up and yank the light around like an arcade joystick, it will move… but most people don’t really do that.

I find 18650 headlamps borderline too heavy but the capacity gains over 18350 and 16340 make them worthwhile. I would never wear a headlamp using a 21700 battery, unless the battery was separate from the headstrap and attached via a cable, often seen in headlamps designed for cold weather use where you can put the battery “pack” inside your jacket.

We were working under the house running pipe. Wife ha 18350 and I had 18650. Wifes battery died and mine kept chugging along. 18650 is a minimum runtime for me. I wouldnt mind more but the 21700 is too heavy.
