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

Interested
but the price should same as convoy s2+ (14-16 dollar)

Danger is user is all too likely to leave the light knob dimmed very low down but not turn the unit off.

  • Not easy to seal. - Prone to wear and track noise.

Brainstorming ideas of where to locate usb port for seniors. Rubber flap might be hard to peel off by old folks. I also don’t like hiding it in the threads because thread grease will get all over grandma’s hands. Here are some ideas of where to put the USB-C port for reference.

I once saw a flashlight with exposed USB-c port that claims it doesn’t need to be sealed to be water proofed. I guess it uses the same approach as seen in cell phones.

Deep diamond knurling.
Because I like to stroke it.
Slowly.
It feels.
Sooo Niiiiiceee

Bah. I call that the pipe-bomb look.

The existing DV-S9 is a rather beautiful indigo color (the plain blue in the pic doesn’t do it justice), and the red ring is a retainer to keep the slider from falling out, but also gives it a nice accent.

As for ring-lights, the WW SD02/WK20 would be a good starting point. Just remove the detentes and make it continuously-variable instead of discrete steps.

?? It’s perfectly waterproof. The slider has a small magnet embedded in it, and the Hall-effect sensor is inside the light. There’s no opening whatsoever, and to clean the slot, just unscrew the retaining ring, slide out the slider, and clean it underwater, etc., then reverse the process.

Also, the DV-S9 has triple O-rings in the tailcap, so with that, no opening for the switch/slider, and if the front glass is properly secured, it’s about as waterproof as you’re gonna get.

Interested, count me in for 2

Lots of discussion going on, it is even a bit of a challenge to filter out the list-requests :slight_smile:
We are currently at 151 units on the BLF list, plus 67 on the TLF list, which makes 208 total.

Although the imagination can go wild on how to make maximal use of the magnetic ring, and the extra tailswitch comes up as well sometimes, I will indeed stick to my guns with just a ring that works as an oldschool radio power/volume knob: dented in when off, rotate for low to high (with either dents with discrete modes, or a ramp), rotate back for high to low and click off.

Once (if) this light exists we could try to convince Sofirn to make a flashoholics version, more output, fancier user interface, maybe add a tailswitch. It is not what I personally find interesting though, such flashlights exist already, what can only be added to those is a BLF-approved user interface and of course a BLF-friendly price.

I mentioned tail switch above but I think tail switch is only beneficial if Sofirn can’t figure out a way to completely stop standby current. Otherwise, I see no point of having a tail switch to complicate things.

Flashaholic version with quad emitters would be pretty sweet :heart_eyes:

Personally i would love to see the driver become available separately (as Sofirn drivers often are), at least, if it’s a PWM-less, true Constant Current driver.
In fact, i think a nice driver is mainly what needs to be developed for this light.

Interested in 2. Could use some grandma lights to give away to parents. The SC31 was great in this regard and I’ve given away a couple of them as gifts.

+1 to sub lumen mode. You never know you need it until you’ve used it. After that, it’s a must have.

I don’t see the point in limiting it to 500 lumens. If it will reliably step down from 1000 then Grandma can quickly see what’s going on in the neighbor’s backyard. The brand new Wowtac A7 looks simple enough. With a rear on and off switch (and memory) and a front switch for modes. It’s basically an updated A1S with micro USB external charging and 1 inch shorter. The new A6 is also pretty easy to operate and at 3.88 inches it will fit in any of Grandma’s pockets. Both are only available currently in CW but it looks like NW is coming. I think both of those are easy enough for 98% of people to operate. Edit, I will likely try both the A6 and A7 if and when they come in NW.

I made the same mistake, when I saw “Magnetic Ring”, but no, this light is not Infinitely variable.

it just has 3 modes, like the magnetic ring on the Jetbeam TCR-10

as stated the lowest mode is 10 lumens, no moonlight… grandma does not need moonlight…
the next mode is 100 lumens… grandma does not need infinitely variable output…

this light is not for flashaholics, its for grandma

the title of the thread is unclear, it gave me the impression that it was a brainstorming thread, to develop a new BLF collaborative design. It is actually an INTEREST thread, for a design that has already been decided.

For those of us wanting infinitely variable, moonlight, etc, this is not the Droid were looking for.

Those premises are not written in stone though.
If it’s possible, there will be stepless dimming.
Besides, the steps between 10, 100 and 500 Lumen are huge.

I understand that magnetic ring fanatics like you can be disappointed, I own the Jetbeam RRT-01 and it has an amazing low moonlight and supersmooth ramping behaviour.

But this is simply not those flashlights. I already explained that the magnetic ring is not intended as the ultimate flashoholic gimmick but very simply for its intuitiveness and self-explainability. That quality has a stepped mode ring just as well (maybe even better) as a ramping ring. If making a ramping ring is just as possible for the same price I will go for it because many people want it and it does not violate the design goals, but personally I like the simplicity of discrete modes better.

Same goes for leaving out moon, if added it would violate the self-explaining requirement of this light.

Is it therefore not a flashoholics light? I do not agree. As a flashoholic I can really enjoy goodlooking, well-made and well-functioning flashlights. Maybe the simple ones even better than ones with lots of bells and whistles.

not a problem
my wallet is happy

you did a good job of explaining that the light you designed is not infinitely variable

I agree discrete modes, and simple designs can be very useful.

I respect your project and initiative. I do not mind that it is not a design that interests me. And Im happy that you are producing a light that interests many others.

Carry on :slight_smile:

Merry New Year!

ps, in a future design, I suggest Titanium and Infinitely Variable :slight_smile:

Huh?? The title does not say that it is a brainstorming thread and it does say that it is an interest thread. Your impression can not be caused by the title AFAICS.

But I fully accept that brainstorming will happen, as with every BLF-thread. Part of being on BLF, and highly appreciated because things come up that I had not thought of.

No BLF-light can be fully collaborative or they will never happen. the LT1 has a strong influence from DBSAR, lots of design decisions are his, supplemented with ideas from BLF. Same goes for the Q8, most decisions were made by the team and Thorfire. Are they not BLF lights?

This light was inspired by BLF-experiences and my personal experiences with non-flashoholic people, supplemented with how I think such light should look like, and will be futher supplemented by suggestions in this thread. Having an old contact at Sofirn, I took the initiative, made a list of requirements and asked for such a light and it took half a year for them to trust that it is good idea. The requirement list is what Sofirn’s cooperation and price estimate is based on, and the interest from who are already on the list is based on these requirements too, and so I will guard those requirement. It generated thusfar interest for more than 200 lights so it can’t be bad.

So I will continue to have a strong say in how this light in this thread might become, and the final say is very much by Sofirn. As for if “the design is already decided”, it has not even started.

:beer:

I’m a little confused right now…

Personally i see no need for a twisty ring when you only have a few fixed modes.
There are already lights on the market that have that.
The old school radio knob idea i do like very much, but that implies stepless dimming i.m.o.
But then the indentes on a few levels would stop making sense too.
