I love seeing all the opinions, some closer to truth and some pretty outlandish. FWIW, pure 100% oxygen free copper is orange in it’s raw state, bright beautiful orange. So is Tellurium Copper. Don’t believe me? Cut it on the lathe and see… The pink hue comes from handling it…a reaction to the oils in your hand. Pretty sure SinkPAD lists their copper stars at nearly twice the thermal capacitance of their aluminum stars, not 30% better. That should be worth something, considering the source. (Al’s 210.0 W/m.K, vs Cu’s 385.0 W/m.K) At 210.0 W/m.K * 30% the result would be 273 W/m.K, obviously copper fares much much better at ~83%+ gain over Aluminum. I have a Hoop pill waiting for this light. Triple something or other it is! And I also just read recently that the anodizing gives Aluminum it’s thermal emissivity, the dye to change it’s color adds nothing… it is, after all, just dye in microscopic amounts… (Type III being better than Type II as it’s a deeper ano) Thanks JDub, and Simon, appreciate the willingness to please.
Specific thermal conductance/conductivity and specific volumetric capacitance/capacity are very different properties of material.
Copper has almost 2x times better spec. thermal conductivity (Sinkpad numbers you mentioned), but spec. volumetric capacitance is only 30% better.
Spec. volumetric capacitance determines how much temperature would rise when material receives thermal energy/heat.
Just noticed that these are all sold out now.
Mine shipped this morning, so the three week countdown to here has started. Thanks to Simon Mao and J-Dub74 for making it happen :+1:

I just ordered but wasn’t sure what options for driver or led was available, what are the available options.
You can basically ask for anything that’s available in another version of the S2. You can see the older S2 configurations here:
https://www.aliexpress.com/store/product/Free-Shipping-Convoy-S2-Gray-Cree-XML2-U2-1A-AMC7135-3-2-Group-3-5-Mode/330416_1614328969.html
and the newer configurations here:
https://www.aliexpress.com/item/desert-tan-S2-flashlight-with-XPL-HI-led-inside-and-ar-coated-glass-biscotti-firmware/32820745681.html
Other tweaks may also be negotiable, possibly at an extra charge.
I went with a 7135×8 Biscotti driver and an XPL HI U6-3A LED, along with AR glass and a smooth reflector. Basically copying one of the new Desert Tan S2+ configurations.

I’ve never turned a S2 into a triple… What’s the easiest way to do so?
If i could get a triple Nichia 90CRI drop in that works with the A6 driver that would be great.

You have to make or buy a spacer.
Copper is best, aluminum is good…
Kiriba-ru sells some, for a reasonable price IMHO
+1! Bought some from him and I’m happy with those!
I didn’t buy the S2+ copper but this surelly looks pretty!
Modders, show us what you’ll do to yours :smiling_imp:
Was one of the first to order it, but had to cancel because I had not specified led and driver, et cetera.
Apparently this caused the light to re-appear in stock only moments ago. And I (re)ordered the (truly) last one. Sigh…
EDIT: And 15 hours later it is already on it’s way to me :partying_face:

Great, doesn't it? :-)
Mine is going to be a custom build with H1-A 3A boost driver and an XHP50 90+CRI G4 35G. Gotta decide if I'm gonna put a 10º or a 5º TIR on it. Up to 1600+ lumens OTF if I'm not mistaken, I could increase driving current a bit but it's going to be gifted to a non-flashaholic lady (a very smart person).
Cheers ^:)

Mines on the way and I ordered it as a host. It’s being kept to build out as a future gift. But if I take a liking to it then I’ll keep it.

This sounds interesting, please do post about it when you built it

Mmm, had to order one for a gift. Host only, will be powered by an H1-A with a CRI90+ XHP50. For the price difference, Simon will add a requested 16mm 5050 DTP board, holster, diffuser and gift box. :heart_eyes:
Cheers :partying_face:
Barkuti, isn’t the H1-A 20mm? I thought the S2+ used a 17mm driver. I think what you are proposing would be an awesome build, so I’m just wondering how you are going to do it. I might be off on the driver dimensions or maybe there’s another H1-A I’m not aware of. I was looking at the one on KD. Thanks.

Yes, but take a look at Jensen567's S2+ builds . Since I have a powerful hot air gun I'm gonna solder the H1-A to the pill in a similar way (I also plan on slightly biting the H1-A board for the pill indentations).
Cheers ^:)

I cannot believe I missed this light!!
I certainly hope there is a batch #2 in the works…

Wow, I just got the host version and it’s pretty nice. I was planning on gifting it but now I’m going to keep it. Now only if Simon would make 18350 tube for it…
