Yes, please stop
interested, please put me on the list.
should be great for wife and parents
Okay. And sorry for the rude reply earlier, which i deleted.
but please buy a Sofirn C01 for your bed side.
No problem, hope your new year is better
So do i… 
Only you. And, obviously, you’re too young to care. Yet.
Funny thing, though, about being interested in flashlights — we get to learn what experience is like for other people who use them. Experiences differ.
So older people find they need to get up more frequently during the night to pee, and need to make the effort not to screw up their sleep cycle with blue-white illumination, while also needing brighter light to get around safely due to other visual changes: lower contrast, smaller pupil maximum opening, and” yellowing of the optical lens.

Here, this illustrates how normal aging affects the lens of the human eye:
Your time will come, grasshopper.
There have been a few requests for a moon mode in this light and personally I’m a big user of moon modes.
But I have intentionally left a really low mode out because in the way this light operates this would be the first mode when switched on. First, non-flashoholics I expect are not fanatic moon-users and nevertheless it will always be the first mode they get. Second, literally everyone who ever tried my flashlights (they all start with a sub1lm mode) did not notice that it was on and thought the flashlight did not work. I like to avoid that in this light.
And moon is not going to be a hidden mode either because this light will not have hidden modes.
10 lumen to start with is recognisable and a nice low useful for everyone, for close-up tasks like reading, I’d like to stick to that.
Only in case infinitely variable output makes it into the final light, then that automatically will include the sublumen modes.
Glad you’re sticking to your guns. My mom, who is 75, only uses 1 mode of the 2 mode light I gave her. It’s probably 20 lumens or so. My 47 year old ex never uses more than 1 mode because she forgets it has more. She “gifted me back” a light I gave her because she thought the light was dead despite putting in fresh batteries.
(it has both a tail switch and a control ring, she kept forgetting to turn on the tail switch.) Funny thing is, she’s not a dumb lady. They just dont care or think about gadgets the way we do.
I recently gave a thrunite cat v6 to a 57 year old lady who lives next to me, for checking her animals and scaring off coyotes. I showed her the u/i a couple times but I’ll bet she never finds turbo on it unless I show her a few more times. Luckily, high doesnt throw that much less than turbo in the big picture and the light will serve fine.
Honestly she acts older than she is- she’s only 10 years older than me but came from a different generation I guess. I grew up with the first handheld electronics.
Slightly older people came from a time when things just had on/ off.
Edited to say, I’d be in for 3 for sure if it has a nicely detented ‘off’ position in the ring, and no tail switch, and substantial knurling or other grippy features on both the ring and body, and big print delineating the positions, and a high contrast ring, and a lanyard hole on the tail. My mom uses a neck lanyard on her ‘going outside’ light to keep easy track of it.
Please can I request that it fits long protected cells, like the ones sold by the big brands that are often 70mm or more, this means that a reliable well known cell can be recommended, rather than stuck with unprotected cells.
Some lights, like the D80v2 cannot fit a 70mm cell despite the two springs.
I like this idea. Reason being, that if it does have parasitic drain, even slight, it could potentially drain below 2.5 volts if left unattended for a while if it was put away with a low battery. Muggles would not know, and just recharge it potentially causing an unsafe condition. So I would most definitely want protected cells for my moms light.
Yes!
Of course that is what I mean!
Glad someone gets it. Bone is my shorthand for what Jerommel kindly delineates. Not and heavens forbid the light would be sculpted as some thermoplastic moulded or 3D printed assisted-living aid. I hope that’s clear.
I agree with Jerommel usually these lights look mean. perhaps on a subconscious level our sense is telling us when the going gets rough they won’t slip out. N.B. Especially useful when wearing gloves or holding it for extended periods.
So the head and tailcap diameter larger than the battery tube would be my ideal choice unless we specifically aim to for as slim-as possible design akin for a blazer pocket penlight -also a valid use case. In practice I reckon that one shall find the integration of a viable twist-ring with its magnets and sensors in the available space to be a challenging task, and it’ll be made easier if it can be accommodated behind a larger diameter head. Larger diameter tailcap then protects the mode ring against unintended rotation.
Makes sense.
In either case, it may be useful to have a raised line on both the ring and the light body that aligns when the light is off, to help with tactile operation. Kind of like the little bumps on the J and F keys. Just an idea that would be cool for flashaholics and make no difference either way for someone who doesn’t care.
Hmmm…
Maybe Sofirn doesn’t have to do a lot of designing:
How about that?
Sleek, smooth and yet that ‘bone shape’, but maybe a bit slippery and too round…
>> Oh, by the way, it’s important that the output increases logarithmically. <<
This i.m.o. still looks like the most natural interface, ergonomically speaking:
The travel of these sliders is usually very short though, probably for technical reasons or to keep it simple and cheap to produce.
But the shape is good too, but more ‘manly’ than the previous one.
Not sure about the blue stuff, but this body color also looks nice.
Add a clip and it won’t roll off the table.
Hmm…
It’s a 21700 light.
Count me in for 1 
The slider interface is extremely user friendly but IIRC it’s more of a challenge to properly waterproof.
Interested, count me in for 2.
Preferably nice LED and tint (high-CRI).
Just to comment, there is a Sofirn SC31 (XP-G3, “610” lumens max) and Sofirn SC31B (SST20, “1000” lumens max)
It shouldn’t be, though, because it too works with a magnet in the slider outside and a hall sensor inside.
But i also read here and there that these lights, which are usually quite cheaply made, have some waterproof problems.
They all have visible PWM dimming too, which is why i never bought one.
1 lumen or less please.
Would like to propose a practical fix to the min lumens controversy; geared to hopefully satisfy everyone; and I mean everyone.
- On/Off plus Momentary On/ Momentary Off; via tactile push switch.
- Twist-ring brightness control with 4 or more detent steps.
- PCB has grid of marked pads to set jumper option(s).
- Light ships in its stock configuration with brightness levels and range which are those deemed as best suited for the needs or abilities of original target audience.
- BLF Nuts so disposed can open and mod to their preferred pro-configuration easily by soldering in a well-defined marked jumper link. Thus access sub-lumen/lumen moon and/or enhanced high lumens range.
The above scheme has the advantages that:
Versatility generates extra interest/buzz around the light.
Markets it to a wider population.
Good for BLF as it serves as a very gentle intro into modding.
Personally; I’d like to have levels spanning between eicca’s stated 1 lumen or less —-> blast grandma into orbit /what’s safe thermally. Two or more in-between steps such as low and high with all modes spaced on log basis.
