The Cypreus - II EDC Custom Copper Flashlight.

Flashlight Modding and DIY Parts
1

I have a new flashlight in my custom lights collection. “The Cypreus” means “made of copper” So this light has it’s guts aswell as the body made up of pure oxygen-free copper. The EDC Cypreus Originally is a small laser host that houses a 12mm laser module and a driver with a small heatsink, I simply loved how it turned out and decided to make another one that could house the guts of a basic 1000lm flashlight, better yet in a edc form factor.

It has been an amazing weekend so far, Here’s my new edc light.

This little beast is a POWERHOUSE, it is running on a single 18350 IMR and the copper body takes care of the heat I can run it on MAX for as long as I want, It does get hot to the touch… Hope you guys like it, It is my latest gem for sure.

Thanks for looking :slight_smile:

cool!

Is that led star just mcpcb or a sinkpad? If it’s a sinkpad this light is ‘par excellence’.

Curse all of you with a milling machine, drill press and lathe. I envy you all!

That thing is beautiful. You should put a nice little carry handle on it as I imagine it would get hot super-duper quick!

nice work!

6

Very very cool…will give ya 20 bucks for it!!! :wink: :wink: :wink:

7

Looks sweet! I’m curious about the weight of that beauty.

I love copper and brass - to many flashlights are black, grey or only silver. Both combined looks awesome and very elegant. Now you have a great EDC. Thank you for showing this.

Have you ever considered making more of that host just like that to sell? Would you?

10

My thought too.

As far as I know, the only stars that feature direct copper to the LED heatsink pad with no dielectric layer are:

  1. Sinkpads
  2. Noctigons
  3. The house brand from Illumination Supply.

I don’t recognize that star, so it might have a dielectric layer under the center pad. You should get an increase in performance switching to a direct copper star.

Would you mind sharing a schematic of your design so that if I bring it to any machine shop they can duplicate?
It is a very clean and elegant design!

Unfortunately I didnot have sinkpads at hand, I just opened up a packet from fasttech a few weeks ago and found a bunch of copper base plated with CREE HJD written on them so i believe they’re for the XM-L2’s. I am sure using a sinkpad will make it upto par, and improve the performace.

The copper takes care of the heat right away and you feel it getting warmer by the second. Although on medium and low you can barely feel it getting more than body temperature that is where I run the light mostly.

Thanks man, It is 6.8Oz incl. batteries.

I have actually, I’ll be able to make more of them , Sure.

Awesome! What are the internal demensions for the emitter/reflector?

14

The reflector is 20.4mm Diameter and 20.0mm Length. Fasttech Sku 1208702
Internal Dimensions are 38mm x 20.5mm. Overall dimensions of head part are 40mm x 24.8mm.

15

Its just simply beautiful ! Well Done!

For those of us like me, who have no idea about machining could you describe a bit about the process. Is it very time consuming?

16

Ooooh!!! Sounds like it will fit a 20mm triple-XPG2 star and triple-TIR optic!!! :stuck_out_tongue:

So if you make this as a host… how much will you charge?

Actually… you should make a version specifically for a triple-XPG2. You could use the same design, but the head could be shorter since a triple-TIR optic is shorter than a single-emitter reflector.

17

Absolutely Love It! Really. It's perfect. I want one, badly! Even more so than the Titanium version and I'm a convicted Ti Freak!

We've gotta talk...

18

I’m going to have to sell a kidney. I think one of these with the Triple xpg driven by a FET would be cool and then another one with triple XMLs and then… and then…

19

It’s not my cuppa, but I like it. You might have a small cash cow on your hands.

Its very pretty, I too envy the skills involved in machining.

How about an MT-G2, 4 seconds of brilliance? Would it work?
