FS: Copper Pill for Courui

For Sale:

$30.00 + Shipping

One copper pill for a Courui.  

I debated (with myself) on how to make this without making it too complicated yet still be efficient at removing heat.  I toyed with the idea of a slip fit piece with a set screw to locate it, but decided that a press fit would be better at transferring heat to the body.  Ideally, I would make an exposed copper section like Dale's M8 and C8 flashlights are.  But I invest a ton of time in those. So I decided on a press fit instead.

The pill is one thousandth over sized for my Courui.  Mine is 1.340" at it's smallest.  No it wasn't perfectly round Frown.  I made it 1.341".  I suggest measuring your light before buying to see if it will fit or not.  If your light is similar in size, it may still fit but may be a bugger to get in.  A .001" press fit is fairly easy with a piece of wood and a hammer.

The shoulder height is designed for a Noctigon mounted XM-L2 or MT-G2.  

Questions?

If Im wrong I’ll delete this post… but didnt someone crack their couri a while back, around where the pill entered the housing and ruin it? I wonder if this might have the same outcome in some lights if pressed or pounded into place. Otherwise, your copper pill looks great.

In this case, the press fit is not terribly tight.  It should tap in somewhat easily.  It would really have to be tight to crack the body.

Thanks guys. If necessary, perhaps some light hand sanding of the aluminum pill cavity with a piece of 350 grit sand paper wrapped around a large wooden dowel could alleviate a tight fit before its pressed/tapped into place.

That's nice.  Too bad I don't have one of those lights yet.

The low mode should be lower.

Sold to pinkpanda.

 

If anyone else wants one, I can make them on an as needed basis.

Freeze the copper pill in dry ice or liquid nitrogen. Makes it smaller till it warms up. Wear gloves and if you use nitrogen, a face shield.

I can't believe it, but it only took one week to go from Pennsylvania, USA to Perth Australia!  I am surprised as hell.  The parts that I sent to Matt took forever.

And I won’t be needing any liquid nitrogen 8)

Thanks for the deal Bucket.

Missed this thread in the first go. Wonderful job. Sweet looking pill for sure.

Must weigh a lot more with that installed though!

So, do you think I could pull the restrictions on my driver and run it at 100% with one of these?

It pulled over 14A for 4481 lumens with no restrictions.

Question…could you make it longer and mill a flat for the e-switch to clear? Since it’s a press fit it will go in a specific location straight down, a flat milled at the correct level would allow another 1/4” or more of copper to be utilized. Am I thinking right on that?

Yes, I could make it longer and mill a flat for the e-switch wires.  I don't have it in front of me right now, but I believe doing that would allow it to extend closer to 1/2" or more further depending on what driver you use.

I have a BLF17DD piggybacked in pretty tight onto the original driver, said driver being stripped. I use short pieces of teflon wire in 3 place to get ground to the piggybacked driver and make a 3 legged support for it. So it’s strong and well grounded, only rises up about 1/2” above the OEM driver pcb.

*Would have to pull it and confirm of course.

I’m wondering if yet more copper could be squeezed in on the top side, filling the area where the base of the reflector sits? This might serve a dual purpose of giving more mass as well as more head contact to spread the heat out further, ultimately getting heat into the big aluminum pill as well where yet more mass would be available.

It isn’t easy getting rid of the heat from an MT-G2 at nearly 15A and over 4400 lumens.

It has also occurred to me that 2 battery tubes might be connected in order to utilize higher capacity 18650 cells in series…

Gazing into my crystal ball I catch a glimpse of an anodized 2 × 18650 tube by Bucket with Dbcstm on a note inside.

Three Tanna leaves to give him life, nine to give him movement. But what if he eats the whole bag?

Dale, I think I would just make a completely new center section for that kind of power.  A copper core pressed into the finned and anodized outer layer.

I don’t have a noctigon yet to mount the led properly but I found out the pill fits over the heatsink. Of course, the head doesn’t screw right the way on but anyway.

With the driver stripped and a BLF17DD Z piggy backed in, 6 Efest 18350’s will do close to 15A to an MT-G2 for 4481 lumens. That big ol chunk of copper you have there will make it doable. I had to scale mine down to 6.23A for 3030 lumens because I don’t have that chunk of copper. I DID put an ounce of Silver behind the shelf though. Smile

I do see your point though about re-creating the pill with copper pressed in. That would be the most efficient.

Could you machine a connecting ring in order to tie two battery tubes together? It might be difficult to align the 3 bays but could be glued once that position is found. Then 18650’s could be used for even greater power delivery and better run time. The corresponding ends of the tubes would have to be milled to remove the anodizing to help ensure ground carrying through for the power level looked at here. Might be a pretty neat trick to get the 2 tubes to thread together snug, in full contact for that ground, with the 3 cell bays in perfect alignment.

Anodizing the connecting ring red or orange might be cool to signify this is a dangerously powerful handheld light. lol (Or Purple Smile )

Using 6 18350’s at 700mAh is the equivalent of a 2100mAh cell at 8.4V. Pulling 14+A from a 2100mAh supply doesn’t give much run time. Pulling similar amperage from a 7500mAh supply would be quite the different story! Multiple 3400mAh cells could be used to tone down the power output while simultaneously providing considerably more capacity and run time.

Think this is possible? Worthy?

I think I know what you are asking.  I think a threaded sleeve could be made to hold two battery tubes together.  It might just be easier to make a 2nd battery tube the correct length.  When I'm done playing with Damascus, my next project is to make a two cell body for my HD2010.  I bought some ano coloring that I hope matches the stock color.  Two 26650's with the 1175b driver should be sweet.

Should be able to push that 2010 to it’s limits. Beware the possibility of frying emitters. I’ve killed 7 or 8, Richard has done in more than 10.

I currently have the HX1175b1 giving an XP-G2 de-domed around 5.6A and making 580Kcd. It’s only doing around 940 lumens. Smile

I don’t know the machining aspects, so don’t know if a collar tying 2 tubes together would be any easier to achieve than boring 3 holes in a 2-in-series tube.

Have fun with the Damascus, really looking forward to seeing that one come alive! Wink
