This is an early Sinner Ti 18650, back when he was making the light with Titanium thick walled tube. He merely made a Ti bezel for the top end and a brass holder for the switch on the back end, then machined the body to have style and grip. So the main light, “head” and all, is one piece Titanium. VERY robust! I got this one from a friend that wanted it built up, it was a host, so I traded him a light I’d already done and flame colored so I could build this one for myself. Since I love Sinner lights, Titanium in general, and am somehow addicted to Luminous SBT-70 emitters, I went with this emitter in combination with TK’s Biscotti firmware. Because the emitter is not very efficient, it’s only making about 469 lumens while drawing 3.64A. I’ll probably give it a few more 7135 chips on the Qlite driver but in all honesty it’s working quite well as is. The moon mode is stoopid low, my box won’t even read it. In a dark room the light from moon barely reaches the floor. Ideal for reading a watch or checking paperwork in the dark without disturbing anyone nearby.
The deep reflector is unusual in this 20mm dia, it’s also about 20mm deep. The Luminus SBT-70 isn’t very efficient, but the round die really plays nicely with this reflector. 
The Titanium bezel is so lightweight you can barely feel it in hand, it houses a nice AR coated glass lens.
He used a solid copper bar to make a pill that threads in, I re-flowed the 20mm Noctigon directly to the pill for maximum heat sinking. It’s about an inch long, with a Qlite driver that has 4 extra chips inside and the Biscotti firmware that ToyKeeper wrote for Convoy.
I did some machining on the base of the reflector to ensure the contacts would clear and the silicone sleeves on the wires wouldn’t keep the reflector standing too high. On this one, I’m leaving the AR coated glass window in place on the emitter so this reflector sits down directly on top of this thin glass and it’s supporting metal “window” as Luminous calls it.
You can see that the tube is raw inside, just the right size in native tube form to accept an 18650 cell. 
The brass switch button floats, so it can rattle some, and it isn’t weather sealed. Not a good camping light. I added a spring to the brass contact button with a wire bypass in it as I chose to use the Qlite driver with it’s very short and stout contact spring.
The tint on this SBT-70 is a 96 CRI daylight white, it has a slight rosy hue to it that is very pleasant on the eye. This next shot is looking straight into the moon mode, barely glowing but showing that blue outline that is classic SBT-70…
It’s probably not the perfect light, but it’s a quality early production from a guy I call my friend, Sinner, who has come a long way since he first started making flashlights. His newest creations are as good as any light out there, in my opinion, and his exotic Mokume Gane lights are Stunningly Gorgeous! (the only thing budget about the Mokume Gane light is that you have to budget to get to one. the people that make the bar stock work hard, and like to get paid well for it, unsurprisingly. )
Thanks for checking it out.
