I understand the objection to a sub-lumen moonlight where there are a small number of fixed modes, even though it’s a feature I like to see on most lights (I do not care about it on dedicated throwers or large multicell lights). If, on the other hand it’s possible to have continuous dimming then I favor going as low as the hardware can do reliably. If it’s not bright enough, just twist the ring farther.
Is there a reason why it might be cheaper? I confess not to know about these types of firmware. Seems to go against the original OP ruling on not having hidden modes… Murphy’s law means at some point in the field modes get scrambled inadvertently. Let’s say by bored fidgeting play or grandma handing it to occupy a highly energetic grandchild as a plaything… Plus I rather like the idea of getting out a soldering iron smelling the flux to do something a little creative. Too much of our world is software driven with hidden menus and software driven software buttons that change. It slowly sends people mad. I hope this light to become a welcome antidote to this madness.
Oh right, I forgot the hidden mode ban.
From a manufacturing standpoint though, it’s usually more cost-effective to use an existing system than design something new. Anduril is already out there and software is easy to test and tweak.
I could be wrong though. Sounds like it’s a moot point anyway.
It would be great to have some mockup samples before even thinking about mass production. Give it to some elderly people and see how they respond.
What we think, and what 'real' elderly people think might be totally different.

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 
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 
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.
