Interest collect for a new Sofirn design: tube style18650, magnetic ring control, USB-C charging, 500 lm max (AKA grandma light)

Im in for one

Oh come onā€¦
Who cares about your circadian rhythm when you have to take a leak?

Only when you ignore the consequences (missing brightness levels, accidentally leaving the light turned on) and alternative options (smaller lights, more dedicated night lights).
But apparently what is low to one is high to others tooā€¦
Maybe one (me?) has poor night vision and others maybe have malfunctioning irises and / or a bad image processing.

Well, i never said anyone was too dumb.
Itā€™s just that some demands have unfortunate consequences for the rest of the UI or the modes.
As a rule of thunmb, every step up with 3 times (some say 4 times) more brightness looks like twice the brightness, and makes for quite an ideal mode spacing.
You can bypass that with stepless dimming, of course, but in practice that usually means ramping by means of pressing the one single button you have, so thatā€™s not ideal either (because itā€™s never exactly right or you press too long, etceteraā€¦)

Iā€™m fine with moon mode, as long as itā€™s hidden by a long press, but thatā€™s a problem for tailswitch lights.
I use a light when i want to see properly.
For me a 100 Lumen lowest mode is dim enough, but warm white (and of course high CRI) is a bit of a must for me late at night.
But i can understand this can be too much for others, so iā€™d say 15 to 35 Lumen is a good lowest mode.
But thatā€™s for a light thatā€™s capable of 1000 Lumen or more, and then you need at least 4 modes to have decent mode spacing.
Hey, or a stepless dimming ring like this one. :slight_smile:

Okay, iā€™ve said more than enough about this here.
Sorry for being a butthole.
This is not my favorite seasonā€¦ :weary:
ā€¦or maybe iā€™m just a bit of a butthole sometimesā€¦

Yeah, youā€™re right.
This was not the place to start this discussion, at least, if weā€™re going for stepless dimming.

Interested

Still love these 100 horses pulling in 100 directions discussions on BLF.
You know what the best part of that is: most of their buttholes are pointed at the same spot.
Maybe we should investigate if grandma can live with 1 lumen. And if not, crank up the Amps till she does.
You can add a diffuser for those who are blinded by the light or canā€™t find their way back to the coffin.

Red suspenders can be really cool though, if you combine it tastefully. :smiley:

But besides that, i think a stepless dimming twisty ring light would be great for anyone.
Or is that perhaps also my flashaholism speakingā€¦?
But i.m.o. manual stepless regulation by sliding or rotating is both practical and natural.
Like an audio amplifier with a volume knob, as opposed to a + and - button.
Like a simple (old fashioned) portable radio even, where turning to minus until ā€˜clickā€™ it turns off.

But it was actually off topic hereā€¦
Itā€™s just that iā€™m always looking for affordable drivers, and good ones (constant current without PWM) are hard to find.
So i was happy to see Simon (Convoy) stocks a bunch of new drivers, but then i saw the terrible mode spacing (or rather low or middle modes that are simply missing), which is caused by the addition of moon modes i will never useā€¦
This is a direct result of the loud moon mode fan club.
They want to use their 5000K 3000 Lumen lights at night where they sleepā€¦

.

Please tell me to stop going on about this hereā€¦ :person_facepalming:

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 iā€¦ :wink:

Only you. And, obviously, youā€™re too young to care. Yet.

Funny thing, though, about being interested in flashlights ā€” 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, andā€ 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 Iā€™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, Iā€™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 youā€™re sticking to your guns. My mom, who is 75, only uses 1 mode of the 2 mode light I gave her. Itā€™s probably 20 lumens or so. My 47 year old ex never uses more than 1 mode because she forgets it has more. She ā€œgifted me backā€ 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, sheā€™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 Iā€™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- sheā€™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, Iā€™d be in for 3 for sure if it has a nicely detented ā€˜offā€™ 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 ā€˜going outsideā€™ 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 thatā€™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 wonā€™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 itā€™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 doesnā€™t care.

Hmmmā€¦
Maybe Sofirn doesnā€™t have to do a lot of designing:

How about that?
Sleek, smooth and yet that ā€˜bone shapeā€™, but maybe a bit slippery and too roundā€¦
