That die looks too small to be an XP-G to my eye. I would have guessed an XP-E LED
Thank you for noticing that, I believe I was mistooken

In which case I believe the clicky in question may be worth less than TreeFiddy ;-)

Definitely an xp-e. Was this ever modded? I've never seen a stock HDS with a mcpcb like that. Milkyspit bored a clearance hole for a 10mm dia 2mm thick mcpcb board when he xp-e swapped my old 140n.

Hi everyone.
I just received a custom tactical and it is fantastic. I ordered the SDR50 led. It's the perfect tint and 300 real lumens is plenty. What a difference from my 14 year old RA Twisty. The Twisty is still my work horse but this Rotary interface is magic.

Dan is making me a holster as well. Thanks Henry for making these awesome lights!

The sapphire lenses used the last year or so have the same light transmission properties as the UCL glass. No difference. This is the sapphire that has the tan/gold anti-reflective coating on it.
I replaced a glass lens with a sapphire lens today
I confirm that the output after the swap stayed the same.

The sapphire does have the Tan AR (left):

fwiw, the Sapphire lens weighs 4.2 gm, the glass lens weights 2.5 gm. (HDS glass lens not in the picture)

What a light! Sapphire lens, tritium bezel. Amazing.

What emitter is in that one Jon?

HDS part?
Nope it is a (very good) 3rd party part.
