A lot of people will want a proper sub lumen moonlight mode. Simple 3 or 4 mode UI. No blinky’s. Good efficient driver. I am not big on charging in the light but, I know some folks really like it. Dual way clips always seem a little bulky for me. I like a common clip. It would be nice if it was fully captive and not a clip on type. Deep carry as well. Color choices seem to get people excited. Of course Ti, Brass, and Copper seem to be hot choices as well.

I love 14500/AA lights so as long as it isn’t terrible, I would buy it.

I love to see when flashlight companies ask the community what they want, welcome to BLF.

As far as this new light, it would be a good idea to give an approximate price point to design around.

I would recommend 519a LED, LH351 has bad red representation and greenish tint, not as popular.
Depending on host design it could be integrated charging or need to have the battery removed, both are good as long as it doesn’t use a rubber port cover.

A good dual clip is also very nice to have, but many of the 2 way clips on 14500 lights are not very good, a good normal clip is better than a bad dual clip. Captive clips (ring between tailcap and body) are the best option as they don’t fall off easily.

For the UI of tail clicky lights, I think most people like it when it has 3 or 4 main cycle modes, with a moonlight mode of less than a lumen. One of the most important features is that blinkies (strobe, battery check, SOS) are not in the main mode cycle, and having a non-memorized shortcut to turbo is nice (for example 2 fast taps).

Having an efficient driver is important to most people when the light uses small capacity batteries, for maximum runtime. A buck/boost would be perfect if it can use 14500 and AA.

Here’s my pick.

LED: 519A/ LH351D - I am fine with any as long as HiCRI and well-focused.
UI: ML(1lm) - Low(5%) - Med(30%) - High(100%), I personally prefer memory mode.
Battery: 14500 for max output.
Rechargeable: I always buy without battery, but it might be a good idea to provide built-in USB-C charging as any option.
Clip: sturdy deep pocket
Color Option: Titanium > Copper > Brass; release at different period.
Aesthetic wise: NO fidget function incorporated into the design.
Budget: around USD50

Thanks for stopping by, LOOP_UNIVERSE!

Welcome to BLF! Cool thread.

Here’s my suggestions:

LED: SST-20 4000k, XP-L HI, or Osram CSLPM1.TG/CSLNM1.TG would be my preference. I think stock domed 519A doesn’t have near enough throw - but it will be the most popular recommendation here I’m sure. Multiple LED options like 519A and Osram CSLNM1.TG would be awesome.

UI:
ON/OFF: Single Click
Output select: From ON, press and hold to cycle Eco-Low-Mid-High-Turbo
Turbo: Double Click from on/off
Strobe: NO, or hidden
SOS: NO, or hidden
From OFF, Hold click to go to <1 lumen moon, then hold click again to go to main group starting from eco. Moon not memorized
From OFF, 3/4 clicks to battery check: light will flash/blink 1 flash=<25%, 2 flashes=25-50%, 3 flashes 50-75%, 4 flashes 75-100%
From OFF, 10 clicks to select: Mode memory on, always start on eco, always start on turbo. blinks once to confirm selection has changed.
Optional: From OFF, 4 clicks to lock/unlock the light.

Output(With Memory): Moon: <1 lumen, Eco=5-15 lumen, Low =30-50 Lumen, Mid= 100-150 Lumen, High= 300-350 Lumen, Turbo= ~600+ Lumen/max for LED choice

Battery: 14500/AA, or 14500 only

Rechargeable: Battery with TYPE C Charging, sold as an option - PLEASE do not use direct charging with a rubber flap! No rubber flaps!

Clip(Deep pocket): B. Common clip, C. Captive Clip - Either would be fine. I don’t like dual-way but I’d live with it.

Color Option: A: Black. B: ANYTHING besides black would be cool!

Material: A. Aluminum. Start with aluminum to make it as lightweight as possible and keep the price down. Maybe add copper or titanium later.

Make it as THIN and lightweight as you can. Body diameter: ~17-19mm, head diameter ~18-21mm.

Make the reflector as BIG and DEEP as you can fit into the light. No matter the LED, try to get as much throw out of it as you can, even if it has to be a few mm longer.

I LOVE the design of your SK01s. It looks very cool. I think you could make a very nice-looking AA light too! Excited to see what you do.

That light looks really cool tbh

Welcome! I have to wonder why you said the SK01s isn’t a perfect light. I think it’s absolutely magnificent. Whatever your next light is, I’ll be buying it

I was walking in the beach recently and being able to go from a dim (or bright!) wide beam down to a tightly focused one to shine on distant buildings is amazing. I was even able to focus it down to burn some dark cardboard.

Actually, enhancing that capability would be great. He love to be able to start little fires.

More power is always great. How about something like the Maxtoch Owl with 4 emitters and optics to combine it into a single beam?

Well, you have mentioned one, the capacity, tho you may use spare 18350 battery/batteries to backup the runtime. We have thought about making a 18650 body, but the body just doesn’t look like its belongs, you know what I mean, right. :blush:

Overall, we want to blend ideas from friends here into our products.

15

I am not sure if this UI would be possible with a tail clicky, it would need an e-switch. Maybe it could distinguish between fast tap and slow tap instead?

1 Thank
16

Great point, now we have common tail switch and E tail switch. Which kind do you prefer?

17

I prefer regular reverse-clicky switch for tailswitch lights with more than 2 or 3 modes, with the exception of Anduril UI. Not sure what other people prefer.

18

BLF friends, which kind do you prefer, reverse-clicky switch or E switch?

1 Thank
19

Given the options, reverse clicky, no/toggled memory (or shortcut to moonlight if e-switch), moonlight, and a good deep carry clip is mandatory. No strobes unless well hidden, and it has to be tailswitched. I’ve been looking for the ideal AA/14500 light for a very very long time, and this has the potential to be it.

This one will be tail switch for sure. Thanks for your suggestion for both options.
