KDLITKER C8.2 XHP50.2 Review

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 :

It has KDLITKER logo on one side

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 :

Bottom side , with the driver held by a retaining ring :
