You might also want to ask over in !micromobility@lemmy.world too but my favorite headlamp is a Zebralight W51 - one button, can be powered by a single AA battery (I use Sanyo Eneloops for rechargeable but it's nice to be able to source a battery from anywhere in a pinch), waterproof, lightweight, pocketable, and doubles as a regular flashlight. Good amount of coverage flood-wise but can project decently well, and at the lowest setting it lasts 40 hours.
Thanks for the suggestion! I didn't know about this community, just subscribed. I might post there too later. I can't find the W51 to do more research unfortunately. But I would prefer a 21700 battery since I would like to match the battery with another flashlight I have in mind for camping purpose.
No problem, happy to help! Hmm, unfortunately, it looks like that one was discontinued. Shame, it was a great light! Looks like there's a similar model (502) they're making now: https://www.zebralight.com/H502pr-Photo-Red-AA-Flood-Headlamp_p_175.html
I also use a Sofirn BS01 that uses 21700 on my singletrack MTB that I converted into a commuter/touring bike and it works pretty well, though if you use a battery that big it'll limit how light the light can actually be.
That said, I do like my BS01 pretty well and they're pretty affordable: https://www.sofirnlight.com/products/sofirn-bs01-led-bike-light-teck
A 21700 is fine for the weight. I won't mind I'm fine going bigger than my Thrunite. The only thing about the SP36 is it uses 3x18650, which is quite hefty. It's hard to hold on with the wrist guards. It's doable, but if I can get a bit smaller light I can also just bring a few extra batteries if needed, it's better imo.
Thanks again for the suggestions though!
If you're banking on extra batteries for quick swap-outs, the Sofirn might not be so viable: You have to unscrew 4 screws to pull the battery out. That said, I've run this thing for hours between charges so unless your trip is extra long, it would probably be OK. Alternately, you could get two and charge one while you run the other.
There are probably more ideal lights for what you want to do though TBH.
Yes, I'm looking for a light that I hold in hands. So I don't think these form factor are the best for my use case. I want to aim it at the ground (I need to see holes and cracks in the road), but I also need to aim it at street signs or something I want to see in the woods for example.
It happened a few times that my Thrunite battery was all spent before getting back home. But maybe it won't happen with a 21700 though.
I'm disappointed in Sofirn for not making the battery in their bike light field-replaceable without tools. They're a real flashlight company. They know how to do this.
It's not ideal, but I'm just glad the battery isn't soldered in.
