Package and content:
The lights box came in a bubble wrap envelope, shipping time to Germany was 13 days which is good
The light comes in a card box
In the box is the light covered with bubble wrap
It comes with:
- pocket clip
The anodisation of this light has litle texture it has no visible defects
The knurling is not too agressive.
Comparism and teardown:
Size compared to other 18650 lights the UT20 is shorter than other tail or side switch lights
UKing, Imalent DM21TW, Nitecore P12, Klarus XT11GT
Beam color is cool around 7000K with a Cree XPE sized LED, the beam has some artifacts from not equal shaped plastic reflector, around the hotspot is a darker area
The LED is reflowed on a aluminum star
The reflector is made from plastic with imperfections and not well shaped
compared to another Cree XML2 6500K light at medium mode, blame my kitten they dropped those lights like 10 times before I could make a picture
The hotspot is pretty narrow, almost no tint shift between spill and hotspot
The light can be taken apart easily nothing is glued or press fit, the driver can be lifted without disassembling the switch cover
The light has a tail cap with one hole for a thin lanyard
The light stands on the tail rock solid
The head has a diameter of 28.9mm and 20.8mm visible reflector
The lens is from cheap glass without any coating the edges are sharp
The light can be run with one unprotected flat top 18650 batteries, or you have to remove the button on the switch side for protected
The driver is cheap Chinese crap
The driver has a charge circuit and 2 LEDs
The Head
The shelf is 1.5mm thick, but its pressed in not one piece of the head
The MCPCB is cheap aluminum without DTP
The LED is perfectly centered
The glass lens rattles and is not
The light is not waterproof, the tail cap, head, tail and bezel have o-rings, but the lens one is not tight enough
Only thing is they could have added some lubricant to the threads
The USB cover sits tight and seals the light
The switch has a good feeling
Tube and Tail
The tail cap is anodized and the inner section is machined, the tail PBC contains a stiff thick steel spring
The threads are triangular cut and not anodized, so not very sturdy
Both ends have a spring made from steel and gold plated
the light uses a short soft spring on the driver and a long stiff in the tail cap
Driver and Battery
contains MCU, charge regulator, a 0.36Ohms resistor, tiny FET, switch and green+blue LEDs
The mode spacing is not good
Battery current with a 4.2V LG HG2
low 175mA
mid 0.58A
high 1,15A
Battery current with a 4.0V LG HG2
low 135mA
mid 0.43A
high 0.9A
The switch is illuminated blue when the light is on, and red flashing below 2.85V
USB micro charges with 0.5A
even at 1A this LED makes only around 100 lumens
Beam shots:
Compared with Jetbeam Jet-1 MK running with NiMh at 150 lumens
compared to a 6500K XML2 around 1000 lumens
Modding:
I sanded down 0.5mm of the head, so the bezel does some pressure on the o-ring and seals the light
User Interface
a short click turns the light on
a 2. press changes to medium
a 3. press changes to low
after like 10 seconds the light locks that mode and another click turns it off
Conclusion
The light is build cheap, no solid shelf, angry blue LED with low brightness,
it might be worth for modding
Positive:
- low voltage warning with red LED in side switch below 2.85V
- USB charger
Negative:
- very cold blue LED which is not bright at all about 100-150 lumens
- PWM in all brightness levels
- beam profile is not balanced very dominant hotspot no corona and low spill
- driver has no LVP that shuts the light off especially in combination with only fitting unprotected batteries
- mechanical production overall below medium, especially the not sealing o-ring of the lens
