A small 123/LS light (Long/pics)

Candle Power Flashlight Forum

The optic's O.D. has to be reduced to ~.655". They were then shortened (from the front) to .375" long. (I know a "hungry" shop that this would be perfect for. /ubbthreads/images/graemlins/grin.gif ) A screw machine house ("Brown & Sharp") might be a lower cost alternative to a CNC house for the 3 machined components??

This would be the general idea for the light: we're talking about offering the parts kit, anodized and all. Basically, you'd just drop in one of the MadMax or BadBoy modules and away you'd go.

The combo of this body with already reduced optics to be used as a host for a MadMax or BadBoy module would be a huge hit.

Thanks again, everybody! (Esp fellow engineer Tomas!)

The design is totally straight-forward. The aluminum wall thickness is a uniform .050," not counting the threads which are 11/16-24 NEF, where the "wall" drops to ,025" or so. It's kind of a scaled-up Arc AAA, and a lot easier to turn on/off with one hand. Hopefully, someone (Peter!) will take the design and run with it! Ethics prohibit my doing a production-run from the shop at work! I do not have the time to chase having a bunch of parts made from outside vendors. (My employer throws me onto the street, could be a different story /ubbthreads/images/graemlins/grin.gif .)

I don't normally read this thread but I saw your bat signal. /ubbthreads/images/graemlins/smile.gif

First, let me say that I am truly impressed with your design. Making the LS smaller is a passion of my heart. Could you please give me a call at (480) 752-8554 x202?

Traditionally, the challenge to making the LS smaller has been mostly with the optics. Smaller optics tend to not focus as well or as efficiently.

It sounds like it is more than just filing off the outer diameter, and we all know that the optics are important.
 
/ubbthreads/images/graemlins/ooo.gif /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/popcorn.gif Peter is getting in the game! I started a thread in Elecktrolumen's page about Elecktrolumens having the largest and smallest LS flashlights. Can't wait to see how this story ends!

I love the concept of the upcoming ARC LS4, and I love the concept of a smaller, no-frills, simple, LS flashlight. A price around $100 would be cool too. The question is who will make the MiniLS and when can we buy it?
 
One concern--does this battery tube have unusually thin walls? I'm wondering how else the OD could be so small. Any concern about crushing it if you sit on it with keys in your pocket?
 
Not counting the diameter of the optics (which is being reduced in this case) the battery seems to determine the width of the unit as a whole. Given that CR2's are on average 16mm vs the 123's 24mm, this light could in theory be made even thinner (and shorter)!

This is sick... Even if you don't go the CR2 route, suppose a HD is used without optics. Instead of optics a relatively simple reflector is machined into the copper (or even better Al and then polished!!!) slug where the reflector walls are long enough to press the lens and o-ring into place. You'd get more efficient transmission of light w/o the optics AND you'd save the cost/hassle of turning down NX-05s.

OK, combine the two ideas with an Amber or Red-Orange being driven directly and you save even more space by leaving out the converter... /ubbthreads/images/graemlins/naughty.gif

I wish I had a mini-lathe (and some training).

OK, I'm starting to get excited now. It is looking like this light might actually reach limited production.

The Sandwich Shop drop-in sounds like an excellent design change for a "kit" version, assuming that adequate heat sinking can be figured out without making the design overly complex or fragile. (My absolute best LS light happens to be BB400 based.)

If heatsinking is a problem with the drop-in design, I'd rather see the existing reg used, as I don't want a light that is "short bursts only" but a genuine serious use light.

Optics question: If a "perfect" mini-optic for this design can be hand made from an NX-05, could copies of it be cast, using it as a core for the mold, less expensively than machining/fitting/polishing a hundred? Just a thought.

Imagine: A solid-state, high brightness, rugged, water-resistant, general purpose light the length of an Arc AAA and the diameter of a CMG Infinity.

I want one.

That would leave a tab in the smaller optics? If the Stock nx-05 is turned down, the tab is turned down with it, but if you injection mold the small optic, you'll have a tab and less efficiency?

Why not a SE LS with a reflector?? Won't that work minus the size of current optics??

[/ QUOTE ]

if he used s SE in such a small body with a reflector, you'll just have a lot of wasted light because the reflector won't make much use of it.... my 2 cents
 
Whoa! This isn't an auction /ubbthreads/images/graemlins/wink.gif If this light ever sees production our offers will have driven the price up to $300 /ubbthreads/images/graemlins/tongue.gif
Seriously, I hope if a kit is offered it will be quite a bit less than $100. My kids can't eat or wear a flashlight.
 
i thought you are planning to get LS4? /ubbthreads/images/graemlins/yellowlaugh.gif
 
Does anyone else see this as another McLux type rush to the finish line? This time, people are gonna get crammed to the hilt...

Not if I get anything to say about it!
