thanks bro, this sounds interesting, so the main point is:

Simple UI: on/off

bigger size: Make it easier for grandma to find it and use it in the room, 21700 better for choice

Low brightness :500lm, or may be 2 modes—100lm and 500lm?

Side switch with USB Charging port ？

Yep. My mum always used to get those craplights by the dozen. All 3×AAA in the carriers. Whether the 4-for-10bux lights with 9 LEDs, or the showerhead lights with 50 LEDs, she would almost buy them in bulk, because the alkaleaks would explode inside and eat away the springs in the carriers, as well as ruin the contacts inside the lights.

They were all simple on/off, would put out decent (if horribly Angry Blue) light when the alkaleaks would be fresh, but as you know, just a short bit of use, and the alkaleaks start to wheeze and coff and the light gets dimmer and dimmer and dimmer.

And once the carrier gets ruined (yeah, I ordered a pile of spare carriers from Amazon), the light itself is pretty much toast anyway because of the ruined contacts.

She never cared for “modes” nor bright/dim, even in the few showerhead lights that had it. Oh, and she always would forget to turn off the lights, putting them face-down so that you couldn’t see if they were on or off without lifting them up. So especially after getting run down to nothing after being left on overnight, the runt of the litter would usually leak and ruin the light.

Hence, her buying those craplights in bulk, and me buying extra carriers.

I did get “Ultrafire” (they’re not) AT01s and lobotomising the crappy driver to bypass the µC entirely. Complete and total POS light, garbage, but figured it was worth a shot. Then ended up like the other craplights.

So one thing I’d REALLY like to see would be a timer, that after 30min-60min of use, it would automatically turn itself off. Maybe 2min of an occasional blink every 10sec or so, and another 1min of a faster blink like every 2sec or so, plenty of time to just touch the switch and reset the timer, but if not done, the light would just happily turn off to protect the cells. That would even protect the light if tossed into a drawer and something hit the switch turning it on.

And finally, a wider spot to be more of a flooder than a thrower. Most old-timers wouldn’t be scouring the backyard at night looking for sleepwalking goats, but looking into a closet, into a cabinet, in a cluttered drawer, or maybe an attic, basement, or unused room. So they wouldn’t necessarily need a spotlight for lots of throw, but a wider-angle area-light.

So even with a dumbed-down version of the UI for The Muggle, a few extra features would make them a great light for The Grandma, addressing those things that few if any lights have.

You mean the blinking after the 30-60 mins right before auto shutoff?

I would have either one mode or two mode, and more like 50-150 lumen so you get amazing run time as many people don’t want super bright (i would not be able to give some people a 500 lumen light).

So i would say 1 mode 75 lumen or two mode, 50 lumen and 150 lumen.
Off 75 lumen Off
or
Off - 50 lumen - 150 lumen - Off

Also the USB should only charge the battery to 4.0V (for longer battery longevity) and cuts off at 3V. The reason being that it could be months before a future charge. But if the battery falls below 2.5V then refuse to charge it. This is important.

Finally i would make a second light with 1AA battery, one mode 50 lumen or two mode 20-100 lumen.
Off 50 lumen Off
or
Off - 20 lumen - 100 lumen - Off

NiMH charging is not a bad idea but people will put alkalines in it which will make the battery explode upon charging. So perhaps best to skip this.

Finally bear in mind the light will be used a few times a year by many people so the standby current has to be very close to zero. Assume the light won’t be charged for up to two years. I would even add a limp mode, if the battery is at 3V shutoff allow one more runtime of 10 lumens for a minute (once) as a reminder to charge the battery.

I would like to see some flashlights on the CREE XHP70 emitter. Efficiency and power!

interested in this project after talk with my team, This is a simple flashlight, but it is not absolutely simple, Contains a lot of caring for older users.
if going with this project, we may need a place talk more and finally determine the functions and materials we need

Waiting for your C8 class, inexpensive, pocketable and throwy.

Thanks for the GAW.

Yes, my MIL would welcome very much a floody ‘Grandma Special’. Maybe 2, one ” It must be somewhere, not?” because she forgot where she used it last time, and the second one in the drawer where it should be.

I agree with you that the demand for a “grandma” light is fairly large. A first impression of the UI looks simple enough, but the real spec’s are not. In a previous post you revealed some thoughts about it. I firmly disagree with one of your points: NO 21700 battery! Why not, very simple: NO Li-ION battery at all!

If “the general public” considers possession and use of Li-ION cell’s and batteries a risk issue (even in the hands of professionals like BLF-members. Well, at least half of us), it can certainly become a dangerous item in the hands of “grandma”.

I did try to address this in Post 42.
However if the majority think Alkaline/NiMH is the better answer then i can’t complain (which i also addressed).

BTW Wurkkos, having multiple posts in this thread, does that disqualify us for the giveaway?
I hope not.

[Quillz]

Go Wurkkos! Keep up the good work and thanks for the giveaway.As for advice, I suggest you peruse this forum. There’s people with a lot of great ideas and info on what works and what doesn’t when it comes to flashlights.

We will Choose the winners from a random floor in this thread, maybe we should open a new tread of the “grandma”

I like this idea

[Yorick]

Go Wurkkos!

Personally I would like to see more flashlights with both rear and side buttons.
Excellent range of lights, keep going!

[Yokiamy]

Go Wurkkos !

Thanks for the giveaway!
Only advice would be; make the side switches like the ones on the TS21 more elegant, i think they can be improved.

Agree with other comments. Your lights are great because they’re easy to use. Your matte anodising is also very nice.
