Wonderful, thank you both. I may have to look into getting a few 16650's then for my EDC QP2L-X, as well as my backup Foursevens.

In terms of runtime, will it last longer or shorter vs 2xCR123's? I've heard conflicting reports on that in general; 2xCR123 is 3000mah, but each cell is only 1500, vs a single cell that is 2500mah.

Think in Watt/Hours (Watts are a measure of Power = Current x Voltage).
2 x CR123 = 2 x 3V x 1500mah = 9000 mW/hr = 9W/hr
1 x 16650 = 4.2V x 2500mah = 10500mW/hr = 10.5W/hr

So you get more power from the 16650 (based on your figures).

Wonderful, thank you.

So I really won't be sacrificing anything using the 16650 in my EDC.

My only other concern is that I live in Las Vegas - currently 114 degrees, and frequently travel in hot areas as well.

Will 1-3hrs exposure out in the heat with the light in the pocket be too much for the rechargeable to bear?

Well, think of what happens to the 18650-based pack in a laptop. All sealed in, next to heat generating components, they pretty well cook all of the time. Heat is not so much a good thing for them, but they handle it pretty well.

The new clips are definitely an upgrade.

I think this is a cool piece of flashlight history, a Nitecore PD D10 with an old 4sevens logo engraved on it. After I purchased the light I reached out to David (founder of 4sevens if you don't know) and asked him about it. He let me know the Nitecore was used to test their engraving machine.

I contemplated about picking this one up, but it wasn't clear to me what the condition of the anno was. This is actually nicer than I thought. Nice pickup!

Wow! That is a nastagic peice of history, Congrats.

While Nitecore had passed, 47's also dealt with Fenix and a few others for a bit,
during the time before 47's won a captive audience and brand recognition.

Very cool!

I'm excited, because I had planned on getting the lumens and runtimes of my Quark engraved on the light, and that flat clip provides the perfect engraving surface.

Something like:

0.5/25d 5/4d 55/14h 300/3h 780/1.9h engraved the length of the clip.

They're both complete Paladins?
In your other pic I thought the proto was a Paladin body with a Quark head.
But it can't be, as it's blue!.

No, that one's just a lego I put together from parts purchased on eBay. When looking at the two recent pictures, the prototypes are on the right side. A keen eye will detect subtle differences.
