new flashlight design

Hi guys first time posting, I am currently working on developing a flashlight and would love some input on components that you guys would recommend. The basic design of the light is a side by side 14500 set up parallel, rectangular body and I’m trying to keep it compact as possible. the light will be a modular design with a space for mounting accessories like a pocket clip and flush adaptors for keymod and mlok for weapons mounting. My head is spinning with all the different styles of drop ins that i have been looking at trying to get dimensions, the things i need help with are:

1. I would like to find a drop in for the led that is complete with the driver preferably in a brass pill that screws in from the front but is as small of a diameter as possible. from my research it looks like the smallest is those meant for a convoy s2 at 21.8mm. is there something smaller that is widely available or is that about it? not looking for insane output or anything crazy either, just simple and crowd pleasing.

2 The tail switch, i would like to have a metal button that screws in from the outside, i like the buttons that thrunite has on their lights but cant find any like it, is there a small metal screw in button that can be easily obtained?

Overall I’m looking to build a platform that has support already so that the lights could be easily modified and customized as well as make it easy for me to obtain the components to build them.

I have seen the Frelux lights, I like them but I have a different design in mind. As soon as i can work out the dimensions of my components i will be more than happy to share my models.

Welcome to BLF pointermachineworks!

Seems an interesting idea, although I’m not fully conceptualizing it yet.
About the screw in buttons, you have those used in the Convoys with metal button.
I bought 2 here:

As for the pills, ready to use, I guess those are the smaller available, and take 17mm drivers.
You have smaller ones, but not in retail, as far as I know.

Welcome Pointermachineworks.

Lumintop offers a version of the Tool AA, they refer to as the “Tool AA 2.0 HM Homemade EDC Flashlight Kit” that includes a modular LED and Driver drop-on of a sort. It’s definitely smaller than an S2.

Seeking the light.

How about making the pill yourself? Mountain Electronics sells 15mm FET+1 driver, so you could have a small but powerful solution.

Smile, you cannot kill them all.

> The basic design of the light is a side by side 14500 set up parallel

here is one vendors opinion about using Two Batteries

we STRONGLY ADVISE AGAINST THEIR USE. Catastrophic failure can occur when one of the two cells is not functioning correctly, causing thermal runaway in the other cell. There is a significant risk of fire and/or explosion when using two cells.

Your link goes to a light that takes 2 cells in series.

oops,

In Parallel does not have the risks of In Series
thank you PinkPanda

@pointermachineworks, I hope it turns out to be an awesome Two Parallel Cell Light Smile

I hear the AA/14500 Synergy is Two Parallel Cell too

good luck with the project
post pictures Smile

PinkPanda is very savvy about building lights.. hopefully will be able to offer you more useful advice, than I have so far.

Don't forget to make a 2x 18650 version at the same time .Seems like if it's a good design then either downsizing it and or upsizing it makes good sense .

I think a slide snap in mount for a bike light may give it some extra appeal as well as open up another possible market .

 

2xAA side by side done right has always been a bit elusive. yeah it's easy to do it if it's titanium and  the light costs an arm and a leg .

 The old school plastic lights ought to prove it can be done right .

Welcome to BLF pointermachineworks! Good luck with your flashlight design and looking forward to updates.

I’d rather use my flashlight around the house than turn on the lights.

Thanks everyone, looks like I am going to have to make the pills my self. I emailed mtnelectronics and am waiting to hear back about some of there smaller drivers. I started out wanting to use somewhat standard parts but am no going to make nearly every component in house so that i do not have to settle. the design is changing by the second but as soon as i have it a little closer i will be sure to share.

No idea what size (min/max) you want for pills, but czech out fastttech.com first, as they got assloads of pills in all sorts of diameters/heights.

I got like 3 different types of brass pills that fit C8s to replace the crappy featherweight Al pills that came-with.

Pickin’ is less than it used to be, but…
