@Hardusvd70 is that stock light without any mod?
Yes both stock. Just got my JM70 yesterday. Did comparison test between the JM70 and UT02.

Hardusvd70 and Nico raised my curiousity just over my natural laziness, so I opened my other 3 samples of the lights and measured the throw – 11 m from the lux meter (HS1010A) and saving the max value:

Battery 4,15 V start My sample - 2180 cd = 263K1m start / 248K@30 sec
Sample 2 – 1830cd = 219K start / 214K 30 sec
Sample 3 – 1994 cd = 241K@start / 218K 30 sec Sample 4 - 2004 cd - 242Kstart / 228K @ 30 sec
My sample again – 2040cd= 246K – at the end of the measurement. Battery was 4,06V.

So my conclusion from this small batch – it is some kind of lottery, yet deviation is +/- 10% from 240K cd cold start.

Well, to add to my posts: the bezelring on my light is a very pale blue as well, it has 4 of these black markings as well, and the switch cover looks as scratched as the others………….but these are minor issues.

A major issue is that the charging on mine doesn’t seem to work either.
I will try again with the manual switch “on” and post result.

Tip for led not centered: they probably screwed the head on without looking if it was done properly (hence the dirt on the reflector and the rease on the lens).
1) screw the bezelring off and remove everything.
2) blow the dust of the reflector with compressed air (I use a can of compressed air)
3) if not available you can use demineralized water to clean the reflector. Do NOT touch it under any circumstances
4) clean the lens (I use warm water with a litte dishwashing detergent)
5) put everything together but do not screw the bezelring on tight, leave some room so the reflector can move a bit
6) gently tap the light in the direction you want the reflector to move over the led positioning ring
7) when in place correctly, gently screw the bezelring on tight

So far, and especially for the price, I’m quite happy with this light.

Cheers
Nico


I’m finally back home and I tried to re-center the LED with this instruction. But when I screw the bezel back I always end up with LED completely off-centre. Suggestions?

Maybe find the proper centering ring ?

What’s the opening of the reflector ?

Without a good centering ring, I had luck with using aluminium foil between the head and reflector. Don’t have this particular light though.

I’d rather not open the head because while I was away my flat got dusty. So I’ll have to do without a centring ring for now.

I managed to slightly improve over factory by positioning reflector, pressing strongly with my fingers right at the centre of the lens and then screwing the bezel. Worked moderately well on the first try, so I guess I can improve it further.

How does alu foil help with centring?

It can fill the room the reflector has to move offcenter. Almost like a big centering ring. If the reflector keeps shifting to one side, you put a bit more on the side it is shifting to.

Might help a bit improving heatsinking too, filling air with aluminium.

This centering ring is perfect for Jm70 xp-l hi , at least fits perfect on mine (old version , no charging).

Anyone thinking of or already has modding the light for xhp70.2?
I’m considering it but want to hear results first.
