REVIEW – “unbranded Prototype” of UTorch UT03

veröffentlicht am 10. May 2017 in flashlights von

Hello my friends!

i got a Box today with a new light in it. (thanks to Jona from gearbest!)

since its an early Prototype it has no branding, accessories or a user manual
all of my findings and measures may not apply on the final product!


Specs as far as i can see:
3x XHP70 12V in parallel
4x 18650 in series
SMO reflector
side switch with LED

UI (as far as i found out)
short click to switch on (mode memory)
long click to start in Moon
short click goes Low-Mid-High-Turbo-High-Mid-Low-Mid…
long click to switch off (1-2 sec)

double (from any mode) click activates: TURBO 2
short click then toggles strobe-SOS-Beacon
double click to off



i will try to add more pictures, measurements and more text as soon as possible,

but i need to show the first impressions right now Big Smile


Day 2

I took some more pictures

do you notice that also head and batterytube (still glued ;)) have a different color?

another angle

machining marks …

my sample did not get full attention 🙁

the knurling is perfect and gives good grip

the switch is raised a bit to make it easier to find

the status LED indicates the cell voltage (blue/purple-ish/red)


the square cut thread have not been lubed well from factory – i did that to lower the massive amount of force needed to open the tailcap

(seems the Oring is too thick or tailcap to narrow – for my other tests i removed the Oring…)

well done battery “carrier”

no sharp edges

a look down the tube shows the 4S cell configuration


the tailcap of my sample was taken from the Manker shelf 😉

when i opened the (non-glued/non-greased) bezel the Oring to the lens broke

thick lens

clear, uncoated

the Oring on the body survived (dry) + regular threads

the reflector

no flaws

they said prototype – so i say thats okay

the LEDs are not centered good (but well enough) because they do not sit 100% on the spot



N0.3 looks good

soldering on the aluminium MCPCB


my biggest concern: the SMO reflector 🙁
i see a hole in the spot

pointing on a dark painted wall in my “homecinema”




in the video its more noticeable

OUTDOOR beamshots:
will be added when it does not rain 🙁

i made a video tring to show how the light works on different voltages 😉

for the numb3r crunchers:


(Lumen have been corrected compared to a acebeam X45)

Das Donut Hole spricht doch dafür, dass hier XHP70.2 rein müssen.
Dass die LEDs dezentriert sind ist sogar gut, um das Loch zu vermeiden.
Wenn du die Zentrierhilfen einseitig aufbohrst, dass die LEDs beim Zudrehen extrem dezentriert sind, dann sollte das Loch weg sein. So habe ich es bei meiner SRK mit 3x XHP50 gemacht.
