Utorch 1x AA 500+ Lumen Review

Hi all,

This is a pretty good light for the money.


.
.
.

Link for purchase: https://goo.gl/AiUmbF
Coupon code: marui
For any other flashlights at regular price use : GB17LED
.
.

If you have one please let us know what you think of it.
.
.
.
EDIT: There is nothing in the instruction book about this but members pointed this out that you can program the light levels.

1. From the off press the button until it blinks two times. It will come on in high mode , and flash 2 times after 7-8 seconds.
2. 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.
3. Now navigate with single (short) click to the lowest mode
4. It will ramp through 3 different output levels . Single click confirms selected output level of mode and goes to the next one
5. Do the same for all the modes , and when you are in strobe turn off the light with a “long” click .
.
.
(I copied most of these instructions from member giorgoskoks post, but dropped the first step as it was not needed)

Alternatively it can be done as shown in post 4 http://budgetlightforum.com/comment/1090114#comment-1090114

In Him (Jesus Christ) was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.

Just received one. I really like it. Single AA with electronic side switch is one of my favorite set ups. Unlike the many that have complained, my switch functions perfectly. Too bad it doesn’t have “Dragon’s Breath” (oscillating blue lit switch cover) That would have been da bomb. Thumbs Up .

I have 2 of them, a 6500k and a 5000k. Much more impressive if used with a 14500 cell. Love the fact each of the 4 light modes has an individually adjustable choice of 3 intensity levels (called “Hidden” settings). Meaning the torch has a total of 12 available non strobe lumen settings.

Nice Matt… Just watched your vid, good job as always.
Did you re-program your turbo mode? I am ~75% certain they do not program the brightest output for turbo stock from the factory. This also helps explain your ~500L measured turbo. Other members are measuring 650-775 on a cold start, before thermal management kicks in.

To enter the program mode double tap it from either ON or OFF.
It will strobe, but just single tap it a few times to cycle past the blinky modes:
Strobe-SOS-beacon-100% Turbo-Battery check-*PROGRAM*

The Program mode will look like firefly, but just let it sit there and it will cycle through the three outputs for each:
Firefly – LO/MED/HI (tap the setting you want)
Low – LO/MED/HI (tap the setting you want)
Med – LO/MED/HI (tap the setting you want)
Hi – LO/MED/TURBO (tap the setting you want)

When you finish, just double tap to lock the settings.

The most useful hidden mode is the battery check mode, unfortunately its buried deep under a bunch of disco flashers. Would have been REALLY COOL if they made battery check the first one in line. That way double tapping goes directly to battery check, and double tapping gets you back out. It basically flashes once for each ~25%. 4 flashes=100%, 3 flashes=75%, 2=50%…etc.

The clip is horrible and immediately damaged the anodizing…
It’s made of way too thick (stainless?) steel.
And once it’s on, it will not properly hold it’s position, let alone find it’s proper position in the first place…
Had i known, i would have thrown it away immediately.
Similar clip problems we find with the clips of many Astrolux lights, (which are also “Manker inspired”, but i assume Manker lights come with a better clip).

Protected 14500 doesn’t fit.

For the rest it’s a nice light. Smile

Looking for:

5” parabolic reflector (for recoil light)

x2… I am not going to be taking this clip off any time soon. my E11 is a little scratched up. I was more careful with the UT01. Once its on there its pretty dam permanent. Actually, the clip position is the biggest difference between my 01 and E11… one tail up the other tail down.

2. After it blinks twice , release the switch and double click again_*

Alternately you can just double-tap the switch from either on or off position. It will enter the strobe/flashy mode group, where you can tap past those and access the program mode… see my post above.

Thanks much to those of you who mentioned the programming. Smile That was not in my set of instructions but its very good to know. In my case this didn’t boost the max output any, but still very cool. I did notice a slight smudge on the lens of my light which I’ve cleaned off, and also that my 14500 cell was at only 3.95 volts when I tested, so once it has charged and fully rested I will test again to see if any respectable difference is made.

Ohhh… You know I tried that first and couldn’t get it to work that way, but at your second mention I tried again and got it to work. Thank you.

Sure, no prob. that could be a sign of a defective switch… there are a lot of members whose lights have faulty / inconsistent switches. I got lucky and won the switch lotto on my lights. Good Luck!! Its a great EDC light if you get a good one.

I have prevented scratching when installing clips by using snap ring pliers. Just spread the clip wide enough (by inserting pliers tips in center ring of clip) to start clip on, remove pliers, then nudge clip with thumb. Goes on with out a hitch. To remove, insert snap ring pliers at clips end openings, pry gently apart and nudge off. No scratches. I’m using the straight attatchments on my snap ring pliers at the moment.

Regarding protected 14500
Nitecore 750 could work. Or you lay a copper wire in the tailcap to bridge the lock out of long batteries.

(I can’t test this, because I got a dead lamp)

I really like mine (NW verison), I reprogrammed the modes to the way I like it and am running it on lowest to see how long it will go. So far 75 hours of continuous running on Duracell rechargeable (eneloop) and its still going. Very small and is convenient for carrying in your pocket, no visible PWM also sold me on it

I’ve ordered one of these on impulse. But now I see there are issues with the battery size. I thought it was too good to be true.

Can anyone say, if there are any PROTECTED Li-ion cells which fit this torch (without modification).

Alternatively are there any safe-chemistry 14500 cells which both work and fit, again without modification?

Thanks

A Xstar should work

Thanks joechina

The candlepowerfoums review for the Xtar 800mAh “Black” states its length to be 51.0mm.

The manufacturer’s specification states 50.5 +/- 0.5mm

http://www.candlepowerforums.com/vb/showthread.php?385597-Test-Review-of...(Black)

So it does seem to be a_ little _shorter than other protected cells (from what I have seen they are typically 51.5mm)

All I need to do now is find a UK supplier.

Protected 14500’s are an interesting beast. I’d rather have a shorter cell with slightly less capacity, but which fits universally, than this type of dilemma. It seems like laziness on the part of battery manufacturers.

Another think that needs to be noted if trying to use protected cells in this light is they need to be capable of at least a 2 amp discharge. For example the Olight protected cells are only rated at 1500ma discharge so even if they would fit, it’s a bad idea.

The candlepowerforums review implies XTAR 14500 Black are capable of discharging at 2.0 amps.

If I am interpreting the plots correctly, the protection kicks in at approx. 2.7-2.8 amps (question: will there be enough head room for transients?)

The run time until shut down is about 20 minutes.

I guessed the runtime at 9 minutes on high for the lamp.
On review stated a UT01/Manker switches to low at 3.3V. So we have 0.3Ah if we draw 2A

0.3Ah / 2A * 60min/h = 9min

And there is a 2 minute step down in the UT01

I guess yes, people said Xtars are as good as IMRs and nobody said it triggered the protection.

Nice review! Ordered 2 each 6500K. Thanks for the code!

Not everyone can carry around UGLY and still look GOOD doing it

Interpolating in the XTAR battery plots, I estimate the runtime about an hour on medium (0.6A). Maybe a few minutes more.

I’ve never read about a battery check . Can you tell us more please?

Sure…
Just quickly double-tap it from either ON or OFF.
It will strobe, but just single tap past Strobe, sos, beacon, turbo-without step down… the next mode is the battery indicator mode. (IIRC one tap past that is the programming mode). Battery indicator mode will flash to indicate the battery charge level. Double tap back out to go back to the regular modes.

So i recieved mine 10 days ago and the button it now completely dead, I’ve tried centring the rubber button , using switch cleaner on the micro switch below and no go. It got progessively worse first missing a press ever now or them until the current state where it nearly impossible to turn on. I’m asking gearbest for a refund, lets see how that works out. I’m very disappointed because if it wasnt for the poor electronics its an excellent light.

Mine came this weekend, only 8 days from China to north-west England (still waiting for 14500 Xtar cells ordered from UK supplier).

Using AA NiMH cell, seems to work perfectly. No switch or clip problems.

Extremely bright on full, even with this battery. The visual perception of its brightness is about the same as my 560 lumen Lumintop.

I got the 5000K tint, this is quite yellowy on the lower settings.

The button placement is entirely unprotected, so it will be easy for it to be activated in your pocket. On the plus side it always starts in lowest mode. I have mounted the clip so that I can turn it to cover the button, this seems to work well.

The lowest setting is considerably above Moonlight I would say. Maybe I’m on HI(LO) – I am going to try and re-programme it.

I tried this several times and it doesn’t work with mine. It just goes through the blinky modes then starts the cycle again.

So far I have used NiMH battery only, does the Program mode only work with 14500?

@kzb
It seems it’s not correct. Try this: http://budgetlightforum.com/node/51365 First Post, at the end.
Does this work?

I’ve read it is possible to let the lamp be constantly in program mode. Then your instruction should work.
