8 February, 2017

Oerview :




First Look / Unboxing :

Flashlight comes in a simple brown box :


Package Contains :

- Flashlight 

- Lanyard

- Spare o-ring

- Gitd tailcap boot

- Soft cleaning cloth


Extended View :

The flashlight itself :


As you can see , it is a classic C8 styled flashlight . Here are some more photos :

And the C8.2 on the other


Anodizing is matt , and has a nice feel…

It’s head , with great machining and some cooling fins :


It has a little “Warning” logo on the head . I find it funny , if you think that it is on a flashlight


Notice the nice crenelated bezel too

Here we can see the SMO reflector and the nicely centered LED (xhp50.2) :


One more photo coming soon , sorry

The tube . Very smooth knurling , and nice machinng also here :


The tailcap . It has holes for lanyard and has the rubber boot “protected” (not protruding) :


Tailcap’s rubber boot :


And the tube’s threads , on the tailcap side . Anodized , well machined :


The other side has bare non-anodized threads for better electrical connection

The visible part of the pill , with the driver and it’s spring (+) :



A button top battery has a good fit , even if it seems to be protruding a lot because of the long driver’s spring (it compresses nicely)

A quick teardown :

Head , tube , tailcap :



As someone can notice , on one of the tube’s “end” (flashlight’s head side) it has only 2-3 full threads , but connection between body and tube is very solid

Switch’s spring :


And the switch assembly . It has the classic little reverse-clicky Omten switch:


Head assembly :


Pill made from brass , with the xhp50.2 on 20mm KD DTP copper board :


And with the centering ring on :
