I picked up some switches a while back that fit in a 10mm tube and are ~10 mm long. I seem to recall Justin saying they fail pretty consistently above .5A so I’d likely max at 380mA with a clicky. I know higher currents are possible even with the 10180 cell but I want these to be practical rather than pyrotechnical.
Comment deleted as I don't want to get kicked of here. I'll try and get the wife to respond here. It might take awhile as she is a bit slow. Takes after me.
since its a ladies flashlight I think it will be better to have an “easy to find” battery so 10440/AAA.
That’s worth considering but I will be shipping them with battery included. It would be a good idea to consider the recipient before entering.
Apart the fact that making something women want I consider one of the difficultiest things in this world, thinking about this two thoughts pas through my mind:
- Before this I believed making the ultimate thrower was difficult, but now I am glad and realize how easy it is compared to the above the work I do.
- This
” What we are?——- Women
What we want?———We don’t know!
When we want it?———-NOW!!! ”
I wish you luck in this heroic project

Sshh, don’t let them know that we know them that well. It’s our only remaining defense.
10440, XP, and clicky. Can’t wait to see it.
Hmm, what about a micro angle head light?
Sounds great, Rufusbduck! :bigsmile: What I would like (if I was lucky enough to win) would be something along those lines.
I don’t have an emitter preference (in a small light run time is better I think) but did want clicky before I started buying twisties. I think one of those TP4056 boards could be modded to charge a 10180 but I’d worry it was too short to handle vs. 10440 (somehow that TU Nano makes up for it by being slim).
Like the squarish Xeno Cube light? I don’t know how it would feel in the hand, being heavier than a lipstick; maybe not as nice as circular lights.
I’ve started. One will be a clicky angle head and the other will be a twisty.
There is a manual that will explain EXACTLY the flashlight they will like and that will have them eagerly allowing their significant others to spend as much money as they want on their hobbies while attaining the flashlight they so desire
This is the Manual for understanding women volume 1
Good luck 
That’s the abridged version…
I thought it was the index.
Small and unobtrusive on the key ring, nice tint, easily operated with the hand holding the keys.
My wife is always multi-tasking, generally has her arms full of something or other as she zooms about her bizness. Having to operate a twisty she doesn’t much care for. (Doesn’t use the LD01 I gave her)
Hello Rufusbduck. My husband has nagged and nagged me to read the above and give you my thoughts. Firstly I'd like to thank you for thinking of all us poor wives and girlfriends that work extremely hard for you boys to play with your toys. I dont understand the batteries but needless to say we seem to have hundreds of aa and aaa batteries around the house seemingly not doing a lot. If the light turns on and of I'm happy with that. I do have a tiny light on my keyring which my hasbeen tells me is what you are very good at building modified ones. I dont understand what you all see in lights but thanks again for thinking of us better half's. What are you doing later? 
Well, it’s a really good way to waste a lot of time and money without going anywhere. Being able to add a little pazzaz to an otherwise utilitarian piece of hardware is just a bonus. I prefer rechargeable lithium cells to alkalines because I don’t like disposable cells and lithiums are more potent.
I assume this is the evil lovely SWMBO we have heard so much about at the keyboard?
and yes, us boys do love our toys.
Only the weekends to play and not all of them but I got a few things done. To thread the various parts together I found some small brass fittings that with a bit of persuasion can pass a 10xxx cell. Also had some nifty bits of knurled brass made by one of our own whiz kids.
Here is the chosen fitting.
Reamed for the cell.
Some threads borrowed and turned on the drill press. I have a metal hack saw blade screwed to a block of wood that is clamped to the table and with the brass mouted on threaded rod make vertical passes to get a true cylinder cut. 
These will get brazed with an outer sleeve added.
The angle head starts with one of the caps turned down to fit in a knurled bit. There are 3 other pieces of brass tubing that were part of this braze to sleeve the ID down to where the brass pill would slip past the threads.
Here is a pile of parts. Some fins will be added and the head shortened a bit. After the fins it starts to get tricky again adding a threaded bezel.
Simply astonishing. Do you ever think you will get caught loitering at plumbing suppliers? You could make history.
