Utorch 1x AA 500+ Lumen Review

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!

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.

Thanks! Verry interesting.

I googled IIRC, gues you mean sth. else: International Integrated Reporting Council (IIRC) - IAS Plus

IIRC means If I Remember Correctly.

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: Review : Utorch UT01 Flashlight (XP-L V6 / AA & 14500 / e-switch) 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.

Thanks joechina I’ll try that tonight and report how I get on with it.

Hopefully when I get home some 14500 cells will have been delivered….

From off, just hold your power switch down and count to ten or less. It will blink once or it will blink twice depending on which mode driver is in. This is how you get between program mode and regular modes.

You want to see two blinks to enter program mode. Once there then do the double click and cycle through to adjust Low, Med, High, Turbo

There was one time I tried to re-program mine with a fairly depleted NiMH and it would not program. I forget exactly what it did though. I useda fully charged 14500 and it worked just I describe above. So, with a fully charged and healthy NiMH it should work just the same as a 14500.

Is this a re-branded Manker E11? Just wondering.

I believe it was cloned, not built by Manker. Although some of them seem to have the Manker brand on the internal components.
I have Xtar 14500 in mine and they fit fine. I haven’t tested run times. Mine had the bad switch also, the only thing gearbest would offer to do was a 50% refund, that was after they first offered a $3 refund.

Yes this works for me. Except I don’t think I’ve accessed the battery check.
So this method works with NiMH cell, at least to re-program the levels.
I was unable to discern any variation in the highest level though.

Still no Xtar 14500 batteries arrived. The flashlight arrived from China quicker than this.
