Utorch logo & e-switch close-up :

Back side , nice knurling :

Square anodized threads & tailcap :

Tailcap :

Head & Reflector , note the AR coated glass too :

Driver is 17mm , press fited in the head (not glued probably). It has a small brass “post” , not a spring .

Beamshots :

CW :

NW (nice tint , not green) :

How it works (&modes) :

UI : Ultra low – Low – Medium – High and hidden Strobe – Sos – Beacon mode

From off :

Single click (short) turns light on , on the lowest mode
Longer click turns light on , on the last used mode (not available for ultra low mode , because you can access it with short click)
Double click turns light on strobe (you enter hidden modes)

From on :

If you are in a regular mode :
Single click cycles between (Ultra Low – Low – Medium – High)
Double click and you’re in Strobe

If you are in a hidden mode :
Single click cycles between (Strobe – SOS – Beacon)
Double click and you’re in last used regular mode

Measurements :

Doesn’t fit protected 14500 batteries

Stand-by current (parasitic drain) : 0,014mA

Efest IMR 14500 V2 650mAh :

Amperage Draw :
Lowest – 24.3 mA
Low – 133mA
Medium – 0.60A
High – 2.01A

Lumens on High : 775

Intenisty : 2197cd

Nitecore IMR 14500 (NI14500A) 650mAh :

Amperage Draw :
Lowest – 24.2 mA
Low – 132.8mA
Medium – 0.60A
High – 1.90A

Lumens on High : 735

Eneloop AA 2000mAh :

Amperage Draw :
Lowest –
Low –
Medium –
High – 4.2A to 3.3A

Lumens on High : 360

Intensity : 1648 cd

Runtimes :

Actual tested Runtimes (will be updated as i test in more modes) :

High (Efest 14500) : 42 minutes (until first “LVP” warning)
When battery voltage is below 3V drops to the lowest mode

High (Eneloop AA) : 55 minutes (until shutdown)
Medium (Eneloop AA) : 1hr 40 minutes (until shutdown)
When battery voltage is equal or below 1V shuts down

Light has programmable output levels for every mode . Here is a how-to :

1) Open the flashlight , navigate on the highest mode , and turn off the light
2) Press the button until it blinks two times (it will open in highest mode , and flash 2 times after 7-8 seconds)
3) After it blinks twice , release the switch and double click again (It will enter strobe , beacon etc and a constant current output level & regular modes )
4) Now navigate with single (short) click to the lowest mode
5) It will ramp through 3 different output levels . Single click confirms selected output level of mode and goes to the next one
6) Do the same for all the modes , and when you are in strobe turn off the light with a “long” click .

Updates will come for more runtimes and measurements (post #2 update log)

Waiting for the updates and your overall impression Giorgos. Smile

Please specify if you can the max battery length that can fit in it.

Overall impression is really good Smile Very small light , capable of great output , for a small time of course ( limitations are : the capacity of the cells and of course the small mass of all the lights of that size )

Edit : longer cell i have is 50,6mm and works fine .

Very nice, thanks for the detailed review!

Any idea on parasitic drain from the e-switch?

“_High (Efest 14500) : 42 minutes (until first “LVP” warning)

High (Eneloop AA) : 55 minutes (until shutdown)

Is it common for the LVP to keep on draining an unprotected Lithium Ion battery while a NiMh cell is simply shut down via the same LVP?

Thanks for the review! A few questions for you:

  • is there a lock-out feature, so that it won’t turn on in a pocket?
  • can you give us just a brief qualitative description of the mode spacing both with a nimh and a 14500?
  • does it seem to have fairly flat regulation (output remains fairly constant) or does it dim gradually?
  • how slowly do you have to single-click to change modes, without accidentally engaging the strobe modes?

How much PWM with this one? I would also like to know if it has a lockout mode.

Thanks Matt

sb56637 , as i mentioned on the review it it 0,014mA .

Freedom , it is designed from the factory like that i guess .

peteybaby , No there isn’t lock out mode . It has a fairly good regulation , no visible dimming , until battery is not able to provide the required current of course . Only if you press the switch for a second time exactly after you release the switch it enters strobe .

mattlward , i will measure PWM frequency tonight .

No lockout mode? I thought the light would lockout if the head is half turned?

Yes , this is phusical lockout (if light has anodized threads , as ut01 has).

Would you know the lumen values for the different modes?

I might get a couple more while the price is good, if the spacing is to my liking.

Thanks

I’ll give you an estimation :

Lowest – 10-25 lm
Low – 70 lm
Medium – 270 lm
High – 775 lm

Just saw your edit.

Since a 50.6mm cell fits & works, I don’t see why a 50.5mm protected XTAR 14500 wouldn’t. Wink

Do you have any XTAR 14500s (or any other 14500 protected of about that size) to check if they fit?

I have the same cell you mentioned (xtar 14500 protected) , and it’s actually longer (50.9mm – 51mm) and it doesn’t work .

Can you just remove the protective pcb to make it fit?

I have several of those in transit to my place.

we buy light for a brighter tomorrow

Battery’s pcb ? Yes (but not really good solution)

How about clip? I have a similar light with a similar clip, and I can not insert easy, is very closed for the flashlight

Thumbs Up Thanks for confirm. I any case, great light for 14500 unprotected and awesome for NiMH.

Thanks for saying this – https://www.youtube.com/watch?v=PQHn1BFt-u0

The user manual is a complete photocopy of the Manker E11’s, just without the Manker logo.

Without trying to sound too controversial, may I ask if this torch, and the UT02, have been copied out of spite for Manker?

Btw, thanks for the review, giorgoskok. I’m now going to buy more than one.

So, only 0.3-0.4mm length difference makes such a damage... Sad

I guess that there might be even some IMRs that won't fit then.

Anyway, I've ordered a pair of 49.5mm UR14500P and a pair of 50mm TF IMR14500, so I will have 14500s that fit, but... do you think that there might be a problem with flat-top cells? Will the UT01 work with these?

They will fit.
Most IMR without button top work ok
