Review: Utorch S1

Review example was provided by Gearbest. Here is link to this model at store.

I`ve already tested pair of similar flashlights (I believe that there actually no more such a lights that utilizes “convex lens + 16340”) : Sunwayman TR16 anc Klarus MI1C. 1st one was terrible, 2nd one was ok, but with it`s own CONs. So, being offered to test this one, I thought a while whether I need it or now. But, as a greedy guy, I agreed. And don`t regret (spoiler, spoiler!)

PACKAGE AND APPEARANCE

Utorch package is good thick cardboard box with modest design, the same I`ve seen with thrunite and manker products. Such thick cardboard easily survives any journey from stockhouse to your postbox,


Inside – as usuall. Black foam rubber, and flashlight within. Package also incudes: o-rings, charge cable, manual and 16340mah battery.


So, here it is, review hero.

As you expect from 16340 light, it is really short, just 59mm of black matte anodized body.

Threads are small, well lubricated. Tailcap moves on them smoothly with no problem.


Spring at at tailcap is thin, but, well, it shouldn’t` be thick as amperage here is low. So, it is normal for such a flashlight.

As such flashlights should be as much compact as possible, even extra 3-5mm of spring at head at counted, so here we`ve got contact plate. But, that`s the same for all the rest 16340 lights, they are not the sort of flashlights where spring at head is real need at all.

Knurling is unusual, rectangular. Actually, for such small flashlight any knurling will work. As flashlights entirely fits into palm, you cannot drop it. And clip adds a lot to firm grip here, I think even more than knurling itself.

Cooling ribs are small, but OK according to size of Utorch. Something about 1-2 mm deep


Here we get CREE XP – L HD V3 + convex lens. That is really not for wide audience, for fans of lense lights. I`m not one of them, frankly speaking. Beware! Specs says there is HI version, but you can definetely see dome above LED. And there is no use to put dedomed LED beyond lense. at least i dont see any. -)




magnet is strong

Button is small, but as there are a special place for finger in clip, you 100% hold flashlight correctly with finger always upon button.

https://www.ixbt.com/live/uploads/images/04/96/13/2018/03/13/dfd019e4a4.jpg!

Overal impression is positive. This model doesn’t look and feel as best that i`ve seen in 16340 segment of market – olight S series, but still it is good. Especially good when we say about Utorch, brand with roots laying deep in fog.

UI

not tricky

There is mode memory

On with short click \ OFF with long

Cycle through low-mid-high with short clicks

Instant access to moon from OFF with long click

2 clicks in moon activate strobe\sos\beacon

Manual says this: Time off function: in any brightness level, double-click the button
the light flashes once — short time function — 3 minutes after the flashlight automatically shut down
the light flashes 2 times — long time function — the flashlight will automatically shut down after 9 minutes

I couldn activate this feature. But as I 100% don’t need it, that`s ok for me.

I like smooth gradual rise and fall of brightness when cycle through modes.

There is lock in\out with 4 sec hold button.

UI reminds me of Olight. Reminds in positive way.

PERFORMANCE

moon 0.5 – low 7 – mid 100 – high 600 lum.

NW light looks a way better in lens flashlight than CW. Last one seems to be blueish.

Just compare it with Klarus Mi1C

There are no WPM shimmering at any mode

Battery is Lumintop. Capacity is real, 620mah. There are trendy micro-usb charge port with LED indication. 0.4A charge amperage. !

Convex lense means that light distribution is exactly what you expect. Bright evenly lit round with darkness outside. I don`t like this. But I know people who do.

There are no throwing ability as all the light goes sideward. Instead flashlight illuminates a lot of area around. I`d say 15-20meters in turbo is it`s limit.


Range of modes is good, in close area you`ll be ok with low-mid. BUT! It certainly lacks mode between mid and high. Moon is reaaally dim.
Light is well stabilized.


OVERALL IMPRESSION

I find this model better than Mi1C, not to say than T16R.

Build quality is good, light is good (as it an be good for lense light).
They only one CON for me is lack of mode between Mid and High

For price\functilonality ratio I say that`s best choice for those who need 16340 light with lens optic.
I`d pick other Utorch, UT01

but Utorch S1 will definitely find it`s own buyers who need exactly such light in such size.
With discount code USMINI you can buy NW \ CW version fo 26.99$

good news, everyone!

Thanks for the review Narmattaru!

However, you said:

But the image seems to show a HD LED, not HI (or at least, not a dedomed one). Can you confirm that please?

The specs seem to mention XPL-HI, but the LED seems to be different…(or maybe I am confused about how a XPL-HI looks like Facepalm )

Thanks in advance!

yep, i didnt paid attention to this.

seems that there is mistake. that`s HD. I think that`s no use of any dedomed LED here.

Hum, could it be that a XPL-HI could give more “thow” in some way? I never tried a XPL-HI under these types of lenses… Facepalm

i don`t think it`ll add anything as lense will dissipate all the light around

What is the weight of this light? Gearbest says 28g, but I find it hard to believe.

Quote:
moon 0.5 – low 7 – mid 100 – high 600 lum.

That’s too bad. I wish there was something in-between 100 and 600 lm.

Only use for a HI emitter in this kind of light is it lets you mount the emitter closer to the lens. With the emitter closer to the lens you get a slightly wider flood. Even a difference that’s just the height of the dome can give you noticeably wider flood.

Of course that wouldn’t matter in a light like this since the emitter’s position is fixed regardless of what emitter is chosen. As such, for this kind of light HD is better as it gives you more lumens.

I have a Sunwayman T26C that’s somewhat similar to this: an aspheric lens in a fixed mount. Overall, I’m not a fan of this optic system…. you essentially get the flood mode of a zoomie, but without the flexibility of being able to zoom.

That’s…one small step for a Q8…one giant leap…for S1 Mini Big Smile

My guess is that it will be a big jump but…I’ll be willing to try that!

Thanks for the answers about the XPL-HI vs XPL-HD on this kind of light!
I am also wondering…if this is suitable for any kinf of “decent” modding concerning the head (in case the stock light doesn’t meet my “taste”). Meaning: is there space for a reflector on the front?

Thanks in advance Wink

In the picture that shows the bezel, lens, and LED removed from the light, there is a plastic gasket or spacer that could probably be replaced by a reflector, if you get a glass lens to replace the aspheric.

The regular Klarus Mi1C has an almost identical lens setup, but they switched to an ordinary reflector setup for the titanium and copper models, and I don’t think they made any other major design changes. So I’m guessing it should be possible, provided you can get a correctly sized reflector and lens. That, or just go with the Ti or Cu models of the Mi1C.

I think the reason you couldn’t access the timer is because there may be a mistake in the directions.
From your review: “2 clicks in moon activate strobe\sos\beacon
Manual says this: Time off function: in any brightness level, double-click the button “

If it’s anything like the Olight that second sentence should be double-click+hold.

Mayor Glenn Welsch: There's a saying in Missouri, if you don't like the weather just wait five minutes. In Blaine, with hard work, I think we can get that down to three or four minutes.

The jump from 100 to 600lm shouldn’t be as drastic as in a reflector light. I have a H03 as my floddiest light and the difference between 450 and 900lm is hard to see with a battery slightly discharged.
And this light should be floddier.

Thanks Delta_V! I never noticed those versions of the Mi1C have reflector instead of lens.
I will see how this light performs and then I’ll decide if I try to swap in a reflector and lens or not!

Thanks for your answer Wink

Or maybe a TIR optic instead of reflector.

The white wire should be a ground from driver to body. The Klarus Mi1c has the same wire with a terminal and a screw.
As for the lens I have no idea.
Hope Spud doesn’t mind me using his pic from this thread.

Narmattaru, could you check with your contact from Gearbest concerning the16340 USB cell that you’re showing included with this?

There seems to be a controversy if it’s actually the cell that’s included, of if it ships with a CR123A primary instead.

Please let us know thanks.

+1! This may be a factor when getting this light for me too! That and the UI…

EDIT; BTW, in your sample, a double click from ON goes to turbo? Thanks in advance!

Narmattaru, could you check the Ui?
Hold to shut OFF the light and klick to change MODES is a change from other review videos. It was reversed.
Are you shure?
I am asking because I don’t like it.

Maybe I missed it, the review is of the NW version?

He wrote:

“NW light looks a way better in lens flashlight than CW. Last one seems to be blueish.”

In the comparison beam photo I assume the Klarus is the second beamshot? (“Last one”)

thanks for the photos and info Narmataru, congrats on the free sample

compare and contrast
Olight S Mini; click on, hold to change modes, click off.
Klarus Mi1c, click on, click to change modes, hold for off.
Utorch S1 Mini, click on, click to change modes, hold for off.

the modes on each light vary, in particular the 3rd mode. I have not seen independent confirmation whether the brightness specs are accurate.

The Olight is not nichia compatible. the Klarus and Utorch might be.

Olight has TIR, and is available in Aluminum, Copper and Titanium
Mi1c has fisheye or reflector and is available in Aluminum, Copper and Titanium
Utorch has fisheye, and is available in Aluminum

Thanks for the review, Narmattaru.
I wanted to add my impressions and findings after receiving this light, couldn’t find any discussion threads, let me know if this isn’t the place for this info and I’ll post it on the sales thread or start a discussion thread.
Was really hoping this would include the timer but it looks like it didn’t make the final cut.
I ordered and received the 5000k version, the tint is much warmer than that as you’ll see from some beamshots I’ve attached. The output has all sorts of artifacts so it’s an awful wall hunter but it’s a nice little light for most everything else. Don’t know why the tint is so far off but it’s the first warmer light that I’ve liked.

If you remove the bezel and optic for mule operation it is a drastic improvement in the beam profile. A thin lens with DC fix might be perfect.
The optic is plastic and sits on a shoulder to keep it in place.

The clip has a firm grip and stays in place thanks to a fitted recess.
The ramp when changing from HIGH to LOW is so slow it feels a little gimmicky.
Despite some of the quirky elements I’ve ordered another one before the sale ended, the build quality seems great and I have a few mods in mind for one of them.
The built-in magnet and lanyard attachment point give this a couple options that I wish my Olight Ti S Mini had.

OK, while writing this I was looking at my pile of parts and I have some lenses that are the right diameter. I’ll include some mule beamshots.
A consideration when running it this way is that you have to keep pressure on the black conical insert in order to keep pressure against the MCPCB so the emitter doesn’t fry. In this configuration I had to put the o-ring underneath the lens to keep the pressure on. After closer inspection I see that my lenses are just 1MM or so too big and they don’t sit down in the head as far as the optic does, thus the need for the o-ring underneath instead of on top. Will try to reduce diameter with a diamond burr.

Zebralight SC62d (Philips LUXEON T @5000k) on left, Utorch S1 on right:

Utorch S1 stock configuration:

Utorch S1 with optic removed and standard lens only:

You can see that the tint changes drastically without the lens and it almost completely eliminates the rings. As there is nothing to diffuse the output there are 4 noticeable spots in the center, but they blend in with normal use. Will try to reduce the diameter of another lens and will post results.

Mayor Glenn Welsch: There's a saying in Missouri, if you don't like the weather just wait five minutes. In Blaine, with hard work, I think we can get that down to three or four minutes.

Has anybody else the bug:
Lamp doesn’t go to high a second time IF the voltage is 3.8V and lower?

No, mine came with the Lumintop battery (700mAh printed on it).
Edit:
And the manual states it has a battery with Micro-USB.
But there is no word in the manual about the timers anymore.

But can you check if you can go to high more than once with 3.7V on the battery?
It works the first cycle, but then it does only low-mid.
I want to know if it is a general issue.

I posted here:

what do you think is causing these ripples?:

why did you write “other”
I could not find your Mi1c review, but you like the Utorch better?

and, is the concensus that the USB battery is NOT included?
