Handmade AAA Copper Tube Light

This little one is made from some 12mm copper tube, copper squares, magnets, an extendable aerial and an old aluminium marker pen using only small hand tools. Smile

The light slides apart so is held together via friction and neodymium magnets soldered to both the driver board and switch contact which hold on to each end of the battery.
I used cold bluing solution to make it look antiquated.

Three mode memory driver, 0.9A, 0.4A and 0.10A
XM-L2 4C on Copper DTP MCPCB in handmade aluminium pill
Reverse clicky tailswitch
Modified TIR Optic (floody)
Weight with cell 39g

I usually modify lights but this is my first built from scratch (or bits n pieces really) Wink
Sorry i did not take pictures during the making.

Thanks, it was about the only option i could think of without the use of threading.

Got to love the look of aged Cu. Great job by the way.

Very clever way of holding the light together. Great job!

I love it. I’ve always considered making a tube light out of copper plumbing pipe, but could never figure out how I would access the battery without the ability to make threads.

Nice work!
I think every modder has at least thought about how to make a light of plumbing pipe.

12mm Copper tube? That is one tiny (skinny) light. Great light you have built from scratch using your own mind and tools at hand. I love every bit of it. Now for the million dollar question. Whats next? Smile

Excellent work! It’s been a while since I’ve seen a thread on a copper pipe light.

CRX – that is just lush. I love the industrial look.

Well done,

Wow, this is VERY cool! Fantastic work, CRX. Would be so great if at some point you could do a write-up of assembly and where you got the parts. What’s the inner tube you fashioned that the copper tubing slides over? Is it aluminum?

I could see this easily being used as a flashlight prop on some minimalist sci-fi production.

Hey, thanks for all the great comments, much appreciated!

Yes that’s the barrel from a silver aluminium pen, it’s the only piece of tubing i had handy that was a snug fit for both the inner diameter of the (plumbers radiator) copper pipe and the outer diameter of the cell. It is quite thin, approx 0.5mm.

The pill is made from the same pen with a piece of aerial tube press fitted inside to make a ledge on which the 10mm copper MCPCB sits, the LED board has a 3mm round of copper ( made from copper squares ) soldered onto the back which fits tightly inside the aerial tube inside the aluminium tube inside the copper tube… LOL

The driver is potted with RTV silicone inside the pill and filed down to press fit in the copper host with a 5×2mm neodymium magnet soldered on, same with the switch.

Because of the design waterproofing is not really possible so the copper switch cover made from 1mm copper squares again is epoxied to the top of the switch, but there’s a fair amount of thick silicone grease around the plunger and this is also press fitted & fixed in place with thermal adhesive so i reckon it could take a quick dunk. Wink
I also soldered a round piece of 1.5mm solid copper wire to the underside of the outside rim of the switch cover to help with stability. The TIR from an old light is filed slightly to press fit also and sanded on front.

The decorative lines are done by wrapping insulating tape around the light three or four times at 0.5mm intervals to make a guide for a junior hacksaw, i just sit the light on top of open vice jaws and lightly go around the grooves a few times while rotating the piece.

The patina is achieved with Birchwood Casey Brass Black .

The light was made on a whim when i came across a couple of cuttings of pipe from when the radiators were installed, the other stuff i already had and it took about six hours to make.

I’m not sure if I read the above correct. Pens, silver at that, aerial tube, bits of copper and on we go. I think I best go have a lie down and come back and read it again. Silly

Yeah, one of my favorites. It has 3 Nichia 219C emitters now and a 17mm FET driver, pulls over 8A at startup with a 20 second turbo timer to 50%. It’s a fair chunck of copper so just gets nice & warm all round set up like that.

Thanks so much for the details, CRX. Thumbs Up

Looks like a fun build. Also, hadn’t heard about cold bluing before. Might be fun to try this cosmetic treatment out on a copper Astrolux A01. Big Smile

Nice build, thanks for sharing. I’m actually very interested in the tri-Maratac, what is the size of optic and where to get the copper pill?

I have one of those Maratac but the natural patina isn’t as pretty as what is on yours. It must me that Scottish salt air!!! Wink
