:wave: Guys,

Wee bit of show & tell..
I am currently working on a new Lummi 123 light.

The focus on the 123 has been to pull all the positives from my lights so far & to make no compromise with anything.
As you can guess the 123 is powered by a single CR123 Primary or PRCR123 rechargeable.
Full brightness of 200 lumens + can only be achieved with the 3.7 volt PRCR123.
The 3 part design allows some cool benefits.

Whilst the Lummi 123 is still a compact PRCR123 based light there is allot of material thickness making for a good robust EDC pocket torch.

This is early stages of the design process & there will be milled curved lines down the front half (Which I can not do in my workshop) Also Milled lanyard attachment point on the rear + the familiar tritium locator slots & logos.
The 123 is a simple two stage twisty. The 3 part design has enabled a super simple approach as per the other Lummi lights.
Added smoothness between Off Low & High with ultra reliable design.

I need to get a new PCB made for the 123 & finalize the design. There is potential to make the 3 sections from other materials.
Especially the front & middle section which are not relied on for electrical conductivity.
Nothing set with a time scale or cost, I am aiming below £100 for a base model & as soon as possible.

Thoughts & interest is much appreciated. :thanks:

Fantastic!
Can use RCR123 and carry primary backup(s)!

I've always hoped you'd come out with such a light.
Look forward to hearing/seeing more!

Oh, and I'll take one.
 
Very interesting taper design, I'm curious to see how this will develop into an amazing light, I'm sure!
 
I love the style of your lights - you have good taste in bucket loads Rob. The tail is a particularly nice bit of design.

I thought I'd got all my flashlight "needs" covered, well I probably have, but this is a flashlight "want" not to be ignored. If this is an interrest list I'm on it, if it turns into a more concrete list I'd like to be on that also.
 
Very cool. Make one for an AA also and I'll take one of both.

Either way I'll be saving for that light! Pretty sweet work. Can't wait to see the finished product!
 
Very nice work Rob. You kept that quiet!!

Of course, I'm in for one.

So, the deep groove on the tail is intended for lanyards? Very neat. Is this to be a fixed focus or variable?

Presumeably the output on high will be for a longer runtime than your Raw's comparing energy stored in a CR123a to a CR2?


Oh and...Where are you going to put the tritium??


Cheers,


Be lucky....

Count me in Rob! If it does not come to fruition I call dibs on the Prototype if you sell it...:twothumbs:crackup::twothumbs:nana::paypal:
The line starts behind me, the >orb prototype is lonely:crackup::D. I like it Rob, I'm in .
 
How about the two stage AAA Lummi, is it that as far along? Or the two stage AA Lummi? But I will settle for the CR2 version.
 
Rob,

Count me in...and a AAA version would be awesome, too! :)

Looks very promising. I can't wait to see more of it.

I love the raws but they're really the only thing using that particular size battery. I have plenty of things that use the 123, so batteries wouldn't ever be an issue. Stick with the 123 size.

It appears that this is something different than just a 123-sized raw, however. I know you're probably holding back some of the details that may still be in flux, but since you took the initiative to tease us with this, perhaps you'll leak a few more details?

You mention a new PCB, is this a new design? perhaps one that even has a circuit? Or just a bigger version of the raw style contact-pad-to-resister-to-led type board? Your mention of improved smoothness between levels suggests it's something more.

You say a few times that this 3 part design gives you some cool benefits, but other than possible materials you don't mention what it gives you over a two part design. What have you got in mind?

And speaking of materials, you suggest the possibility of "other materials" but you never told us other than what? Personally I'm hoping for titanium, but given you're target price I suspect that'll fall into the "other" category, so I'm going to hazard a guess at what we're seeing is aluminum.

The taper is interesting. Between that and the shape of the base, it looks to be an evolution of the >orb more than anything else. Does it have a name yet?

It looks good so far. I can't wait to see more.


p.s. Is it too early to start pestering you about the Da version? :duck::crackup:
(ok, ok, I'm kidding)
 
Wow! Rob, this could be just what I need! That new "neutral" LED at 200 lumens high and a 5-10 lumen low OR your high efficency 100 lumen version. Let's see more ASAP!!!
 
Looks Awesome!

Will the power be regulated?

BIG :thanks: for the feedback which is really great to here :twothumbs

Its looks to long for me. What is the length at this stage?

Overall length is 73mm which when I compare to other CR123 lights is close to being one of the shortest. Max Dia is 24mm

Sorry no plan to make a Lummi AA based light.

So, the deep groove on the tail is intended for lanyards?

Correct, plenty of room for similar milling to the Raw style lanyard attachment.

Very neat. Is this to be a fixed focus or variable?

Fixed

Presumeably the output on high will be for a longer runtime than your Raw's comparing energy stored in a CR123a to a CR2?

Correct, something like 1 hour on high 200 & about 2 hours @ 100 Lumens.

Oh and...Where are you going to put the tritium??

Most likely in the tail a bit like the Wee.

There is a few things like the milling that I can not show at the moment that will add more style to the unique design.
The PCB will be similar to the Raw Series with two stages & SMD resistors.
Two benefits with a new PCB design is additional heat sinking & the middle section will keep the Light engine tight in place. But will allow the user to unscrew to swap out LE's if desired.
The twisty switch operation is really smooth. Achieved by the 3 part design & precise machining.
Nothing set on materials, but there are many options. One thought is a Stainless steel tail section & Alu mid & front. So a combination which could include other non metallic sections...
You are correct the proto is all Aluminum.


Does it have a name yet?
Yes Lummi 123 or just 123.

Will the power be regulated?

Not electronically, staying with the simple reliable resistors.

Let me know if I missed any questions.
Great to see the interest at this stage.

:thanks:
 
Rob, I have been hoping that you would produce a 123-sized light for a long
time to have the extra-benefits of runtime, output and an easily available cell.

If I may be so bold, I think I prefer the current design of the raw and would
love this in a CR123 size.

I'm sure you will correct me, but I immediately asked myself the following:-

I notice that the taper of the head piece is in the opposite way to the taper
of a reflector, therefore surely there will be a piece at the top of the head
which is redundant and may also impede the beam?

Otherwise the reflector would have to be as narrow as the end of the head
which would mean that its less wide than the middle of the light,
which in turn would reduce the throw for a light of that width.
 
Man, I'm going to continue to hope on the AA battery light. I can't see why more custom makers aren't doing this power source. Its gotta be the most common battery.
