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 :
