Review : KDLITKER C8.2 , 1*18650 xhp50.2 flashlight

Great review. Got one of these myself and am pleasantly impressed. Feels like a comfortable 2000 lumens to the naked eye compared to convoy c8 and L6, and slots nicely in between in terms of performance.

Reckon you can convince kaidomain to put a xhp35 hi into the same set up? Even keeping the current around the 4A level? I’d buy that. Don’t have enough time or skills for even simple mods myself.

xhp35 is a 12V led , compared to the xhp50.2 that runs at 6V , so it will be a little more complicated …

An xhp35 running at 2 amps would be awesome in a C8 , but heat wouldn’t be so great…

Huh! I assumed because the xhp 50 and 70 came in 6V and 12V the 35 would also. Oh well, thanks for pointing that out.

On another note, I get a brief bright flicker whenever I enter low mode on mine. Just mine or do other units also do this?

It is a common thing in many lights when going from highest to lowest level, it is hardware-related but can be suppressed by the software. (I’m not an expert).

+1 for me to

Yes , mine does that too . I guess Jos gave a reasonable explanation :slight_smile:

Out of interest, with the H1A driver that is being used, is there an MCU on-board? I've looked at the photos, and everything seems to be obscured by a huge (I assume) inductor?

been thinking of getting a couple, wonder if they would slide some batteries in them for shipping purposes.
thanks for reviewing the light.

You could ask them , they will probably be able to do that.

George, (or anyone who has this) Do you happen to have any convoy C8 to check if the bezel will lego with this?

I’d like to get this and add the convoy SS bezel.

I bought this light and I love it, dedomed the led and the beam is now alot nicer

I will check it later today .

Honestly, this light has killed xpl based c8s for me. They just don’t compete. Yes, they throw a bit further, but you can SEE so much more with this out to 200m.

I’d love to see more lights with the xhp50.2, maybe an updated A6? And bistro UI too.

I almost like it more than my Q8 (don’t tell Miller et. Al. Though!)

I think this is what the c8 should have always been from the start, C8+xhp50.2 is awesome, small and compact and yet throwy especially if you dedome the 50.2! I tried this in a regular c8, with just the shelf and it became too hot with the xhp50. So the pill really seems to help, barely gets warm at all for me in turbo or mode 3 which I normally use. Xhp50.2 gives a much better beam too, h1-a driver is good too imo!

Yes. It helps to block thermal transfert. Integrated shelf have much better thermal R (probably 20deg difference with 50deg host).

Awesome, thanks!

Glad I resurrected this thread :partying_face: I wanted to get more input on this one, sounds good!

Was it hard to de dome? How did you do it with an exacto knife or razor blade?

That’s not necessarily a good thing. The LED will still be producing just as much heat as in the C8 with a shelf. If the C8 with a shelf gets hot, that means it is successfully transferring the heat to the outside of the light. If this host, on the other hand, isn’t getting warm, that means the heat is remaining trapped internally and not getting transferred away from the components. Depending on the output, and whether or not the light has some form of automatic stepdown, this may put it at risk of overheating.

Lived experience is it gets quite warm, but never hot, across the whole torch. I feel it’s more because the turbo is not heavily over driven (which would be a challenge on a single 18650 anyway) like we tend to do with xpls these days.

The xhp50.2 just seems to be really efficient.

I walk the dogs with both this and the Q8, and this keeps on trooping on long after the Q8 has stepped down. I’m talking 10-15 minutes with no worrisome overheating and no degradation in performance.

Just checked the bezel , diameter and threads are the same , but Convoy bezel can’t screw all the way down, leaving a 2mm gap .

Crap. Well at least it threads on the same so maybe all hope is not lost…

I might be able to run it without the lens o-ring to decrease the gap, don’t really care if water resistant. Or maybe stretch another lens o-ring outside in the gap, if it don’t look too bad, or modify/shorten the reflector.

Thanks for taking the time for checking it!
