Utorch SF-01 - UI doesn't seem to do anything

Utorch SF-01 – UI doesn’t seem to do anything

—-

using a new cr123a cell, all it does is turn on and off

no high/level or strobe

what would cause this?

at first it would switch but at random.
i would press the button while power was off, if it went to a good mode, i would press it in and it would stay
then that got intermittent, now all it seems to do is HIGH (though since it will not switch, i can’t really tell HIGH from LOW)

shouldn’t it be switching modes, with power on, every time i do a button tap?

?

i have tried AA alkalines and AA NiMH, same thing

not a bad light, though it is too big for a cr123 really
the light color is a good neutral, i like the pattern – big hot spot, wide floody area too

?

From off , half press 10 times and hold on the last press. It will change modes and shut off. You are now in a different group. Either H only or H,L or H, strobe, low.

The Utorch SF-01 has a so-called 10-tap system identical to the one of Streamlight.
With 10 taps you get from one “program” into the next “program”. See also Link.
The three available programs are: – high/strobe/low, – high only, – low/high

Could it be you are stuck in “high only”? And you have to 10-tap your way out of it?

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

I had problems similar to yours as well as the lights flickering when I got my 3 SF-01s. However when I went through the programming modes they became rough solid, except for 1 flaky tailcap. Try going through the programming modes and see if that helps.

And all 3 lights were dimmer with a new cr123 than an AA Eneloop for some reason.

The difference between high and low really isn’t noticeable unless one is paying close attention. Maybe yours came programmed as high only?

Yes. It will cycle between the three each time you 10 tap.

is it supposed to change modes while the power is on?

my switch doesn;t seem to interrupt power unless you click it – but then it is off

Also, when off, half press quickly to cycle through the modes . Full press to select the desired one.

Being a forward clicky, it changes modes when off.

Mode changes are done on a half-press when the light is on and it has to be quickly done. For example when the light is off and it’s in high/low mode a half-press will turn it on in low and an immediate half-press will put it in high. Fully pressing the switch will leave the light on in high.

they even say the switch is ‘reverse clicky’

these have to be the worst ever!

Don’t tell us you are UI-challenged Wink

Someone here discovered it was a 10 tap . I don’t know how he figured that out except it looked like the original.

I’m definitely UI-challenged. As bad as this one is, it’s even worse that it’s not marked “SF-01” anywhere (mine are now) for when you need to search for instructions.

Best thing to do is to use the streamlight instructions that you can find using a google search.

i’ve got it now, thanks

now i think my switch is flaky though – not debounced or something, i have it set to HIGH/LOW mode ( no strobe ), and it is still hard to pick the right one

H and L are hard to tell apart in daylight.

I gave two of these away to friends. I didn’t even bother to tell them about the programming thing. I was thinking about just putting them into H mode only but decided on H-Strobe-Low to let them have fun. If they inquire, I will enlighten them. Big Smile
