Review : Amutorch JM70 xp-l hi , single cell VFM thrower

It seems to be vety consistent at least…. :person_facepalming: . :wink:

That sux…… :frowning:

Did you switch on the tail cap switch? It breaks the contact and battery is not charging even if the indicator light is on.

P.S. my blue bezel has the same black marks as yours, but I seem lucky with well centered led and good reflector.

If only it had a 4000-4500k LED inside instead of a 6500k one.

Would have been dope to give to a police officer of mine with a magnetic connector.

Stupid me :person_facepalming:
Will try again when I’m back home.

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.

Anyone try to unscrew the tail switch or take the driver out to do some mods .

Nope.
Monday I’m @ Djozz’ and we will bridge both springs (so the “tailcap” switch will have to come out) and maybe replace driver wires.

Some good news though!
I put in a cell with 4,04V, turned the light on and used the onboard charger.
The charging port light on the light went red and went dead after some time.
Took the cell out, measured it and……4,18V.
Nice.

Grtz

So……………focus couldn’t be improved, the reflector is not the best ever but it will do.
Both springs bridged and measured with Djozz’ Mobilux (my elcheapo LX1330B always exaggerates CW around 9-10%) and now we got a dependable 240Kcd.
Not bad as I paid slightly over €30,00.

I suspect the XP-L HI in the light is not the latest version so I might upgrade to V3 (I like the 3C binning a lot) at a later point.

Cheers,
Nico

JM70

Utorch UT02

Measured at 10 meter distance.

@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 - 242K@start / 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.

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.

They have AM33 - 3x18650 and XHP70.2 with same reflector.
