[Group Buy Interest Poll] Tiny EDC keychain light done right - BLF/Sofirn-style!

Needs LVP and REPLACEABLE BAT :stuck_out_tongue:

No, a clicky would be much larger, so it won't appeal to most BLF members.

It's just what I really want.

Interested

If the battery the battery is included and is replaceable… Interested (voted).

I am interested if

1) The battery is easy to replace.
2) The modes are spaced for my needs. High runtime needs to be atleast 1 hour 30 minutes. Medium around 50 lumens or a little lower.

Would be very interested if it

  • came with Type C rather than micro USB
  • looked nice

In general in lights this small charging adds a lot to the size and if it’s micro USB I’d prefer to not have it at all.

The problem I find with lights of this type is that they’re unusable for practical use. If the high mode lasts for 30 minutes, its useless for me. Then the medium mode is so low that its as good as not having a light at all. The high and medium modes are important to me.

I hope this light is the first to change the mode spacing.

Clickies are large …but tail e-switch (UF-10 style) would add roughly 5 mm to the length without affecting diameter.
18650S style would carry even smaller penalty but would require a custom MCPCB and therefore limit LED swappability,

A tail e-switch would work for me, but I don't know if most people would be interested.

There is no way high mode will last an hour or more on a 10180 battery. I was told the drive for 200 lumens on High is because 100 lumens is not enough to sell and BLF members push for more and more lumens. If you disagree, make your voice heard! If there are enough interested buyers maybe it could change…

Personally I think a High ~100LM and Low somewhere between 15-40LM would be good since there is also a moonlight for the really low mode. With such a configuration, Low would be very usable and offer a good amount of runtime, while still having High for bursts as needed, and having moonlight for really long minimal lighting.

I think having a useful middle brightness mode is the most important one to get right.

What is the value of having a tail e-switch? Where would the keyring go (I don’t like them off-centered)? Wouldn’t it add cost and self-drain issues?

I have my gripe with the SST-20 and this optics. None of my many C01S is in its original condition, so I do not intent to buy another one. Such a small light needs to have a larger, softer spot. IMO.

Please make suggestions!

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.

I’m interested, especially if it has Moonlight, Low, High modes.

Maybe it would be possible to add a small side switch like this flashlight has: https://detail.tmall.com/item.htm?id=542841365120&skuId=4041112377452

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.

Interested.
High CRI is essential.
Don’t skimp on runtime nor usable amount of light on medium, better to increase (battery) size.

I like 10280 more than 10180, but I would still get a 10180 flashlight if it's not a twisty.

(I don't like twisties.)
