Does anyone know if there are any full copper hosts that accept 1x 18650? (hopefully also with a copper pill)
I know there are some talented Machinists, but I was hoping there might be some reasonably priced pre-made hosts out there. Seems like its just Lumintop?
I agree and I’m really looking forward to it, but just so kludge is aware — it looks like its coming with a brass pill. There’s some copper parts available out there, but its another part to buy for your build.
I actually agree with you. I like hunting up or making parts for my builds and mods, no matter if its a flashlight or some other type of gizmo. That’s part of what makes it personal — I might do mine differently than what everyone else wants. But the original poster specifically said he hoped for a copper pill and the S2+ doesn’t actually meet that standard, so I pointed it out. That’s all.
Yes. Copper can conduct heat about 3.5 times better than brass, and aluminum can conduct heat about 2 times better than brass.
The whole idea of brass pills is kind of confusing considering it is the major component that takes the heat away. :weary:
I had no idea about a copper s2. (time to do some reading). I can probably manage to have someone machine a copper pill for it.
When is it expected to come out? Will it be a limited run?
The first sneak pictures of the copper S2+ shows a standard brass pill, but I would not be surprised if that is a prototype and they had not made a pill yet for it, and that the final light does have a copper pill.
Aluminum is better than brass ?… until you try to solder to it . Pills are brass for a reason , A copper mcpcb is all you need but this discussion has been had already .
The thermal conductivity coefficient is also know as the lambda coefficient. The formula goes something like λ = W/mK.
Where W = Watt’s, m = meter between heat-source and heat recipient, and K = degree Kelvin.
The (specific) mass of the material is non-relevant in the formula. Wanna reduce the heat-flow, put in more insulation (m).
The mass of the material becomes relevant when the subject is heat-storage.

FYI In the Netherlands, brass is often referred to as yellow copper (geel koper), and regular copper as red copper (rood koper).
Ya, I didn’t consider soldering. I have soldered things to aluminum, but had to use a mini torch to heat it up a bit before using the iron on it.
My favorite way of doing it; is by using the thin rings that get pressed into the pill. Those have been super easy to to just solder the ring to the driver, then press.
I guess its no big deal having brass pills with copper mcpcbs, but if its gonna be a fancy copper host than might as well also have a copper pill too; so I can burn my hands faster!
Hopefully it is just a prototype type deal.
