Not longer than a C8, shorter than most, nice 26650 capacity and performance, bigger reflector/more throw than a C8, and quality finish.

Just the way I like it. Big Smile

Yeah, as a host only for a reasonable price I’d buy it. Similar in size to my short Convoy L2, has the advantage of a momentary switch.
But my L2 outthrows the Utorch with XP-L V6 dedomed.

Sure, I got lots of lights that out throw this light, but the L2 is not as pocketable as this light. Yes, I have an L2 that does 282 kcd @5m, lots of HD2010's, a few MaxToch throwers, a TN31, a BOSS1, a K40, 1504's, etc....  If I go out on a hike, The U21 or this UT02 can make the trip, but the L2 and larger lights will be sitting home.

I guess maybe Texas really is a whole nother country… here, we go on hikes for our health, carrying the larger light can only be better for us as it’s more exercise. Smile

(well, actually, we don’t typically go on hikes, per se. It’s a half mile walk to go get the mail. Can be that or more to go to the Dr.s office at the hospital. Park at the outer edge instead of driving around looking for a close parking space and the exercise is free, available every day.)

Think about it from a woman’s perspective, she carries a purse that weighs 8 lbs, a baby, the diaper bag, 2 bags of groceries and the files you requested, plus your dry cleaning and a 10mm in a shoulder holster with a second mag under her free arm. What’s a flashlight weigh anyhow? Silly (And wears heels while toting all that!) (with a boa constrictor around her chest no less… the bra.)

Got a friend's son who hikes the dessert, sometimes days at a time. To him, every ounce counts. Water vs. flashlight trade-offs, etc. He pays big $$$ to get gear lightweight. All depends. For me, I'm entering parks before dusk because technically they close at dusk. Traffic zipping by... I don't want to make it obvious. It helps if a light fits in the pocket. Actually the BLF Q8 in the back pocket worked out well for that park. Maybe 2 L6's - they'd look like dumbbells, for the exercise smile.

So the problem isn’t the light itself, it’s the need to be inconspicuous in order to break the law? I see… given that you KNOW the park is closed, perhaps you should rethink that. Wink

Sparing ya the rest of it…

71.2 mm is huge. Same here - LK's and BASEN's is all I tried. I'd think all unprotected would fit. Didn't try my KK 26700's.

Hello.

As the resistor mod using an R050 gets similar readings than Manker U21, and I fear it may be dangerous for the driver, I made this mod using an R100 from Fasttech.

These are my readings

Modes:
1- ———-
2- 0,20A
3- 0,62A
4- 1,34A
5- 3,85A.

I ran it in turbo mode in periods of five minutes until the voltage dropped to 3,5V

4,14V. 3,85A. 144.400 Cd.
4,01V. 5,19A. 146.160 Cd.
3,90V. 4,29A. 143.600 Cd.
3,69V. 4,47A. 145.080 Cd.
3,56V. 4,60A. 143.280 Cd.

In five minutes it gets very hot.

At 3,5V turbo mode is not maintained and the flashlight only has four modes.

I’m running one of my UT02’s with 3 R10’s stacked for 4.8amps at the tail cap, no idea what it is at the LED and it’s running fine so far, driver seems to be alright, but only time will tell!

The other UT02 I modded with a MT-G2 on a 26mm Noctigon and a FETDDLDO standard E-switch firmware 6 level driver, and got rid of the stock switch and swapped in a Courui D01 switch using the stock boot and plastic cover, making the click more robust and sharper feeling to me. Had to make a copper driver adapter for the 26mm to 30mm driver pocket out of copper crush washer rings, which spaced the battery tube out, and allowed more room for the (2) 26350’s

At only 6amps at the tail cap, this light handles the heat very well, the beam is super nice, creamy/rosy tint, plenty of beautiful flood and decent throw, lights up the neighbors garage across the street like daylight even thru the street lights glare. In total darkness this thing ought to rock!

I think the mtg2 is one of the most photogenic leds out there:)

My UT02 I received yesterday and it is great.
As it turned out, the flashlight, as in U21 are undocumented modes. To access them: from off hold down the button for 10 seconds. After 10 sec. flashlight blink 2 times for maximum brightness
and turns off. Now we are in a hidden level. In this state, the group Strobe / Breath Flash / SOS added Turbo + (no step down) / Beacon / Constantly glowing blue button.
What’s the last mode I do not understand (solid blue light). With a discharged battery changes color from blue to purple. (Battery indicator?)
Turbo + no step-down: working at room temperature until automatically shuts down due to overheating (when the head temperature reaches 50 ° C).
Also, if the mode is enabled Beacon and we will do two-click a flashlight off. After one click enters in which you can adjust the brightness in Low mode.
It has 21 degrees of brightness and adjusts from minimum to maximum (each click changes the brightness). To store the desired light intensity, a flashlight must be switched off.
Visually Low mode, you can do an equal brightness mode Med1, ie from 15 to 100 lumens.
To exit the hidden group acts the same way: when the light is turned off hold down the button for 10 seconds.
After 10 sec. blink 1 time for maximum brightness and turn off which means dropping the hidden level.
Have fun!

Thanks aslpg for finding out new future and it’s great that you can get low low or 50 lumens if you wish.
Just tried it and it’s working Thumbs Up

Anyone willing to do a runtime and output test comparison between turbo with step down and turbo without?

I just received my UT02. What is the “breath flash” suppose to do? It is found after the strobe and all I see is the indicator light changing from red to purple. Does it do something else? Does it have any meaning?

To show where is your flashlight when it’s in dark
Or when you want to show to your friends that cool “breathing mode”

Will the resitor change the output of all modes, or just turbo
I dont want 50 lumen when in low mode

Как оказалось, в этом фонаре … есть недокументированные режимы. Для доступа к ним, надо при включении фонаря удерживать нажатой кнопку в течение 10 сек. Через 10 сек. фонарь мигнёт 2 раза на максимальной яркости и выключится. Всё, теперь фонарь перешёл на скрытый уровень. На этом уровне к линейке Strobe/Breath Flash/Sos добавляются Turbo+ без степдауна/Beacon/Постоянное свечение кнопки синим цветом. Про последний так и не понял для чего он, возможно, у него функция аналогична Breath Flash, т.е. такой же локатор, но не переменного, а постоянного синего свечения. При разряженном аккумуляторе цвет меняется с синего на сиреневый. (Индикатор состояния аккумулятора?)

Turbo+ без степдауна при комнатной температуре работает около 10 минут, затем фонарь автоматически отключается по перегреву.
Температура тушки достигает 50 °C. При мокром охлаждении отключения не происходит, аккумулятора 26650 хватает на 52 минуты такого режима, но даже при охлаждении тушка прогревается до 47 °C.

Кроме того, если при включённом режиме Beacon сделать двойной клик, то фонарь выключится, а при включении по одинарному клику войдёт в режим подстройки яркости режима Low. Он имеет 21 градацию, яркость меняется от минимальной к максимальной по одиночному клику, для запоминания желаемой яркости фонарь надо выключить. Визуально режим Low можно сделать равным по яркости режиму Med1, т.е. от 15 до 100 люмен.

Для выхода из скрытого уровня надо так же при включении фонаря удерживать нажатой кнопку в течение 10 сек. Через 10 сек. фонарь мигнёт 1 раз на максимальной яркости и выключится, просигнализировав о выходе из скрытого уровня.

Thanks for the translation. But so it will be a little more correct. I think so. Wink

There’s a few UT02 review topics floating around but I thought I’d place my question in this one.

While I’m waiting for mine to arrive, can I ask if anyone knows whether the new short version of the Keeppower 26650’s work in this torch?

I’ve got them in my L6 so it’d be handy to use the same batteries

thanks

G'day mate, ow ya garn?
Yeah, nah good mate

I tried one of mine very briefly and it worked. The only 26650 that I couldn’t get to work was the Klarus battery that comes with the G20 (button top). I also had trouble with a button top protected Keeppower 18650. Everything else worked, which were flat top or semi-flat tops.

I just received my UT02, and I like it overall, but I HATE the switch. It works fine, I just don’t like how it feels. Oh well…

Hi, someone who modified resistance for a r100, could you tell me if the modification is still stable? Thank you!

I’ll try and generalize things, correct me if I’m wrong.

If I buy a UT02 now, it will probably only be 2.5 amp at the battery and deliver 40% to 60% below specs. So non modders should steer clear.

The modders can add a R050 to R100 and boost the power back up to stock levels (1300lm)

If this resistor mod causes the drivers to break, the lights can then be used as hosts. An xpl hi and a buck driver can be installed and you can get above spec output (1500lm).

Does this sound about right?

If so, I might get me one just for the heck of it.

The odds are good since this is still below spec.

Now the R050 is the one more likely to cause problems over time.

Has anyone seen the Manker drivers that put out over 5 amps?

I’m wondering if they originally used a R025 sense resistor (which was later swapped to an R050 to reduce output).
