My C01S is still in the mail so I haven’t experienced it, but I agree that a keychain light needs a good amount of flood and large spot since it will be used at shorter distances.
100 at high or anything that lasts for an hour and then a 40 at medium is good with me. I know for sure I could use this on my keyring. I thought this would be a twisty. No drain and accidental turn on to deal with.
The keyring would need to be off-centered. I think it would add cost but no self-drain issues (I believe drain could be lower than self-discharge of battery) but I might be wrong about that.
Value?
Full Andruil in a light of this size would be a killer feature by itself.
There’s a honeycomb TIR optics that fits the C01S. Someone here on BLF found it. It is very floody.
My preference would be a different LED. As soon as there’s a Nichia 219C underneath that very same optics, you get a really nice beam.
Sofirn and people working closely together with Sofirn usually ignore my proposals, but in case someone is interested, I can do some comparative beamshots.
I'd personally want a stainless steel or ti 2 mode and none of this trying to be the baddest or brightest . i'd be thinking dqg or atom ,Not a pocket rocket ... just a classy light done right .$20 for SS and $30 for ti. High cri /nice tint ,starts in low but a higher than normal low since it's a 2 mode .
Something with only our name on it ...and not cloned by the maker using their name a month later.
For a light in the $10 range, I’m fine with the small cell, sealed design, Micro USB charging, and twisty operation. It must always start in low- no exceptions.
What I would like to see is:
Neutral/warm high CRI emitter.
Aspheric lens for wide, smooth beam with no hot spot, like the Utorch S1 Mini.
Solid lanyard/key ring attachment point like the ROVYVON A8.
How many I purchase will be based on color choices. Anodize these lights in an assortment of colors and I will buy lots of them. If it only comes in black, I will buy 1 light.
Quantity I would buy: 1 for sure. Many more for presents if the design ends up right.
Suggestions:
Modes: sub-lumen moonlight please, always start in lowest (or at least configurable), no memory.
Switch: don’t care if twisty or tail clicky, but important to not have any self drain (no electronic switch).
Battery: 10180 or 10280, but not AAA size (there are already many great AAA flashlights).
Charging: USB Type-C please. More durable, easier to use and future-proof than Micro USB.
Other: flat bottom able to tail stand, with a solid ring hole in its side that don’t affect tail standing. No magnetic tailcap.
