Wow that looks great!
How does the tail stay on? Magnet?
Gotta love how CRX produces more flashlights in 1 month than the rest of us combined do in a year.
Lovely, again..
i’m a little jealous…
Yep. Still have no idea how you do this. Just amazing. Orsm build CRX.

Very nice zoomie! With the performance spot-on.

Very nice work CRX. What size is the square die image, say from 5m to a wall?

Someone please show him how to properly build a flash from scratch.
The man really needs tutoring. Although it’s still kinda impressive what he can do with a coarse file, a chisel, and 80 grit sandpaper.

Go watch the movie “Spectral” on Netflix.
With a couple hours and a roomful of old junk, the guy in that movie assembled enough “Plasma Rifles” to outfit a platoon. Complete with fancy scopes and even a tripod mounted heavy version.
Ok will do. Butt I’m already primed to suspend disbelief to the max.

It projects around an 11” square from 5m.

I believe it’s the first time I see a zoomie from scratch. I have a weak spot for zoomies……and this one is truly awesome.
What are lumens in focus and out of focus?
Thanks, I wanted something in titanium about the same form factor as the UF-10 and there is nothing on the market at a sensible price as far as I could see.
I get about 609lm/ 290lm at startup.

Great build again mate

You’re getting a nice set of lights in this style

Just working my way through the tube
I bought 350mm of the titanium so maybe enough left for one more light.

I really want to build my own EDC some day, something like this.
I still need to work on a design that can focus while using a wavien collar though, I won’t accept anything less than the farthest possible throw

Oh, I thought you already carried around one of your photon cannons for an edc

Haha I wish xD
I used to have a small P5r.2, because it is the farthest throw you can get from a stock light that size.
Then I got an S1R baton II and liked the design, and kept it since it was small.
If I made an EDC with a wavien collar it would have to be 26650 size to fit it, which is less EDC-able, but would still easily fit in my backpack, and it would have insane runtime.

All I can say is WOW. Really like this one.
Yeah, or once the LEP lights get a little more advanced/ compact, should be cool.
That's an interesting project you've started.
Well, finally
