I have been bothering Barry for half a year over this and he and Sofirn finally gave it a go, they will start with the design after the chinese new year, so somewhere February. If all goes well, maybe it will be ready before 2021? But of course as always it is ready when it is ready. The requirement from Sofirn for BLF to do this grandma light is a shown interest for 1000 units.

Some history :

Since the start of BLF every now and then the question comes up what light to give to non-flashoholic people. The answer has long been, to give them the simple AA-based cheapy that is for sale anywhere for a few dollars. Because they can not take care of li-ion cells (they will drain them to death), even a 3-mode user interface is too complicated, they will loose the light so it must be cheap. Etc.

This june the question came up once more in the thread “grandma needs a light”, in which Maverick1947 asked for a flashoholic-worthy light for his grandmother. Since we have USB charging nowadays even in cheap flashlights, the li-ion cell is not a problem anymore to give away, so there are a few ok options now. He bought a Sofirn SC31, which is a good “muggle-friendly” flashlight that will never overheat and has micro-USB charging. The user interface however is still not simple enough for non-flashoholics, and who wants to give away a flashlight with an ugly XP-G3 led?

So, together with Sofirn, and having listened to input from BLF, I hope a new design can be made, with the SC31 as starting point. It will be a flashlight that is interesting enough for flashlight enthousiasts, but can also be useful and given away to almost any non-flashoholic. The specifications will hopefully be as follows:

Specifications

*price under 20 dollar shipped (maybe 18 dollar without/22 dollar with battery option)

*size not larger than the Sofirn SC31, so upper limit 12cm long. (the Zanflare F1 is also a muggle-friendly light but really too bulky IMO)

*this light should be a no-manual flashlight: a short manual will be there, but even without it all operations should be easy to figure out, also by an un-experienced user.

*operation will be a magnetic control ring with off-low10lumen-med100lumen-high500lumen, nothing else (and so not infinitely variable). No other or hidden modes or options. The magnetic ring is at the core of what this flashlight must be.

*Parasitic drain when ring is in off-position must be ultra-low ( <10 microA), so when left in a drawer for a year it should still work

*battery can be charged via a USB-C port, maybe in the threads (well-marked), or else behind a conventional rubber flap. Also USB-C charging is a hard requirement.

*maximum output 500 lumen, thermal control/stepdowns not needed

*Barry/Sofirn wants to go for a TIR optic, not my personal preference but I understand that may be very fitting for this light.

*led maybe Samsung LH351D 5000K 90 CRI.

*first dim and finally shut off at low voltage.

So this will not be a performer in the flashoholics way, but certainly a performer in usefulness! I hope that I did not forget features, I will edit the OP if needed.

Edit: while this thread is up on BLF, people have pointed out some desirable features for this light that I think are valuable without undermining the above specifications of which costs is probably the most important one, so here is the resulting “wishlist”, that is not garanteed to happen but that I will discuss with Sofirn:

Wishlist.

*infinite variable control ring instead of discrete modes

*contrasting colour of the control ring, no ano or different ano, maybe SS for sturdiness.

*small battery indicator/charge led near USB port

*charging works with ring in off-position

*anti-roll measure

*well detented off-position

*fits long protected cells

*ring positions well-marked

*USB-C to USB-C charging works

*18350 tube option for who want it more pocketfriendly

*smooth bezel but with a few small cutouts to see light when bezel-standing

*USB-C socket must be quality, resistent to some abuse

*charging to 4.1V instead of 4.2v, to preserve batteries when constantly connected to a charger.

*option for brighter colours than just black

*USB-port must not be hidden, and easy to spot

I’m not sure yet how I will maintain the interest list, I will at least start it here in the OP, like I did with other projects, but, if it is succesful, adding manually a 1000 names over the coming months by editing the OP will be quite an effort (and I am absolutely the worse with computers so have no clever solutions).

Please comment in this thread if you would like to be in the interest list for a light of the above specifications, and for how many. No obligations, but I would appreciate it if the interest is serious.

The german forum TLF is also checking interest, their current list total is 153.
