Olight S1 Mini High CRI and Utorch S1 Mini NW comparisons

Olight
42 grams w battery and clip
includes awesome USB 16340
Clip works on a hat
Beam is tight with large hotspot
Extra Green Tint around the corona
click on, hold to change modes, click off,
tail magnet is not strong but works, even sideways
no keyring attachment on tailcap
High CRI
Difficult to Open to Modify
Moonlight can be memorized
Strobe is a triple click from any mode including off
modes: spec 0.5-12-50-250-450. my meter 0.3-11-39-181-460/360@1 min, 270@2 min

Utorch
47 grams w battery and clip
includes awesome USB 16340
Clip works on a hat but interferes with tailstanding and magnet use
Beam is wide, with no hotspot
Extra Yellow Tint around the corona
click on, click to change modes, hold off
tail magnet is annoying, it grabs things I dont want it to
Yes keyring attachment on tailcap
Low CRI
Easy Open to Modify
Moonlight cannot be memorized, if it is the last used mode, the next time the light is clicked on, it turns on in Low. I dont care for the UI at all.
Strobe is a tripple clic, but only IF you are in moonlight, otherwise, no strobe access.. very impractical imo.
modes: spec 0.5-7-100-600. my meter 0.2-4-66-445/234@1 min, 231@ 2 min

Worm with N219b for reference

Utorch has much wider beam than Olight. Note difference in color temperatures. The worm is spec 4000k. the Utorch 5000k and the Olight 5500k

lowest modes, on my meter, worm 2 lumens, Utorch 0.2 lumens, Olight 0.4 lumens

under UV the Utorch glows yellow

Tint and Red Rendering, Utorch makes red coral look brown, and makes my hand more pale than daylight does.

the S1 Mini also makes my hand more pale than daylight does (photo exposure from a different day and time)

PWM test. The lights use Constant Current, there is Photographable Flicker or Ripple on the lowest modes, but waving does not show dots. Olight Ripple is about 2kHz, the Utorch is not known, but looks similar.

the light on the left is 3000k, the Utorch in the middle is spec to be 5000k, worm on right is spec to be 4000k. Imo the Utorch is warmer than the Worm.

My daughter wanted my first Utorch so I ordered another. Once it arrived I was curious to check out the driver, must’ve screwed something up because the batcheck quit working.
No longer trusting the light I left it sitting on my desk where it stared at me. Reminded me of HAL9000 so I put a hyper-red emitter in it and will use it for goofing around since who knows what else I messed up on the driver board. Everything else works fine, but I just can’t trust it any more. I’m afraid it may start singing Daisy Bell.

Both.. LOL
I like the Utorch Flood beam much better for use as a headlamp indoors and illuminating work in my hands. The wide even beam is really useful for close headlamp work!
here is the Olight beam indoors, it is a bit of a fuzzy beam, no distinct hotspot Im standing 12 feet from the wall.

and the Utorch, whose beam imo is much clearer, although also has a ring around the outer edge

and the Worm, which has the same beam as your Maratac AAA, with the most defined hotspot

Otoh, I much prefer the Olight UI, and CRI, and the Low Battery indicator light. I like it better for general use that may include illuminating a parking lot, or things more than 10 feet away. I find the beam too narrow to use as a headlamp at arms length though.

Both lights could be improved with Nichia LEDs, both have nasty tint issues. The Utorch is much easier to mod, and less expensive, except when I buy both and then want to mod them to boot. Smile

but the Utorch is a specialty beam, for close work, and does not come in High CRI, so if I was going to pick only one, in stock form, it would be the Olight.

Just like in the UT01, it seems Utorch doesn’t know what 5000K is. They should just advertise it as 4000K warm white instead of neutral white.

Just discovered this wonderful addiction.

I agree it looks like 4000k

one more Hand Palm, attempting to illustrate beam shape at arms length. Note the Utorch beam is the most evenly bright, the Olight has a strong overbright hotspot. so does the Worm. Then note how I “improve” the tint of the Olight with a Lee Filter stuck to the front of the lens w double sided tape. The AssPheric Utorch lens wont let me stick a filter to it. But as bansuri pointed out, the Utorch beam can be improved with a flat lens, and then I could stick a Lee Filter on easily.

Im learning that in actual use, even Low CRI can show relative colors in a useful way. The two samples on the right are both Low CRI.

FWIW, Im finding the wide beam of the Utorch to be Outstanding for my close range, indoor needs. You can see it does not produce any glare or hotspot in the image.

here the bottom right CW light is replaced with the N219b worm, you can see its hotspot is more problematic, and even though the Red pops, it is not necessarily the closest match to the natural light.

I also tested the Utorch S1 Mini NW as a wake in the dark for a toilet break. It works great, and does not look yellow in use.

Im super happy with the Utorch, and for my uses indoors, and as a headlamp for hand work, its wide beam is the most useful, for me.

If I was a bicyclist or motorist, stuck in the dark with a flat tire to fix, I would want the Utorch more than the Olight, because the Utorch beam is so consistent and broad. With the other lights, the hotspot forces me to keep sweeping my head to move the glare off the work.

Two Thumbs up on the Utorch S1 Mini for close headlamp use.
fwiw, there is also a Klarus with the same beam, although the modes may differ. For example the Moon may be brighter. I favor the extra low Moon of the Utorch.

One thing I dont like, is that the Utorch will not memorize Moonlight, but, I can get to it with the press and hold shortcut. I dont like that turning the Utorch off requires a long press, I wish it had the Click on Click off UI of the Olight.

No perfect light, which is why we all have more than one. Hang on to your wallet!

Thanks for doing the comparison. I really prefer true 5000k light. I think I could stand a 4500k light, but that yellow beam of the Utorch would make me angry every time I turned it on! I’d have to try swapping emitters if it were mine. I don’t like that green looking 5500k light from the Olight either, but I could live with it, as I’m sure it’s only noticeable in white-wall hunting. I know 5000k is considered to be the “cool” end of the “neutral” temp spectrum, but it’s the temp that looks the most “white” to me.

As for seeing object colors, your pictures really tell a story. It’s obvious that different lights produce different results. But, as I think you’ve seen, in day-to-day living, any of those would be useful.

Reason is not automatic. Those who deny it cannot be conquered by it. Do not count on them. Leave them alone.

in theory, I agree, in real world use, I dont notice.. Im suprised to admit that, but there it is.

what I like least about the Utorch is that it does not memorize moonlight, which the Olight does.

If I use moonlight on the Utorch and then turn it off, the next single click to on gives Medium! I Hate that! But I can work around it by using the moonlight shortcut, a long press.

Another thing I dislike about the Utorch UI is how slow it is to ramp down from Max to low.. same issue with turning it off, there is a bothersome delay before the light goes dark.

I must admit I thought you were way wrong to say NW shows colors well.. you were right, it works well enough for most uses

Im a snob when it comes to photos and colors, but, Im learning that my brain is much more tolerant (unaware) than my camera.

Thanks for challenging me to expand my horizons.

other Utorch Trivia, the Manual looks almost identical to the Klarus Mi1c, and seem to have similar UI.

and some lumen specs and measurements comparisons between the Utorch S1 Mini and Olight S1 Mini

I prefer the lumen levels of the Utorch Low and Medium. On the Olight, Low and Medium are too similar, I would prefer Olight Medium to be higher.

Another difference regarding lockout
The Utorch on lockout will shine momentary Low mode when switch is held down
the Olight on lockout will shine momentary Moon mode when the switch is held down

I dont like a lockout that does not make the switch stop working altogether. It is easier to just loosen the tailcap.

regarding Memory:
The Olight remembers its last used mode including moon, except Turbo. The Utorch will not memorize moon, it does memorize Turbo. If I turn off the Utorch on Moonlight, the next time I turn it on it comes on in Medium!(nasty suprise)

regarding Utorch battery check, using 2 clicks at off

4 flashes is 4+ volts on my meter
3 flashes is 3.97 volts on my meter
2 flashes is 3.87 volts on my meter
1 flash is 3.77 volts on my meter

the Olight has no battery check, but it does turn on a red LED on its switch as a low battery indicator, at 3.39 volts.

The Utorch is fun to check, but the Olight Low Battery is automatic, so better for someone that is not actively playing with the Battery Monitor on the Utorch

In both cases the USB battery is protected anyway, so it will cut power, at about 2.7 volts.

I like your HAL, here is his distant cousin HALey

I was curious just how much green my brain and camera can tolerate and still be able to tell a Tomato from an Orange

as you can see, in real life with HALey Greene, I could still tell the fruits apart. I wonder if HAL Redman can also tell the difference? My guess is Yes Smile

Maratac AAA w 4000k N219b

and the Utorch as a wide beam headlamp

I dont care for the Olight S1 Mini High CRI beam as an indoor headlamp, too narrow and throwy, would be better for a bicycle light and outdoors.

If anybody wants to buy my Olight, $40 shipped conus, PM me.

Im really loving the big floody beam of the Utorch, and in actual use, the NW Low CRI with yellow tint, is not that noticeable. Whereas the Olight, every time I turn it on, its just too CW for me. Bear in mind Im sitting under 3000k incandescent at home. And I have a 3000K and 4000k Nichias in my Maratacs. I like Warm lights.

look at this 2000k Nichia in a Klarus Copper Mi1c by djozz, I want:

I would like a light that color in the wide beam AssPheric version, like the Utorch has.
I prefer the modes of the Utorch over the Klarus. And, unmodified, I prefer the NW option of the Utorch XPL, that Klarus does not offer afaik.

my newfound love for NW is going to make me consider a Ti S Mini too.. when will it end?

unscrewed the Utorch bezel and removed the plastic fisheye lens to compare the beams

Experimenting with a flat glass lens on the Utorch instead of the aspheric. The beam is cleaner with the glass lens, IF I do not install the shiny bezel. To my suprise, the bezel creates a small center hotspot, that I do not want. I may experiment with blacking out the bezel.

Nicely made ! Thumbs Up

A little mistake however: the Olight SMINI TI is NW…

thank you for the kind support
here btw is the complete feature set, including undesireable features like hold for off, just to inform, also added LED types. FWIW, the Klarus did not get marked as having sublumen, but they do have 1 lumen lows, almost sublumen

I believe on the Utorch that the black centering disk as well as the lens itself, once the bezel is screwed back on, pushes the MCPCB down so the thermal paste can do it’s work. If left without any downward pressure you might run the risk of burning it up if the MCPCB separates from the shelf and has no contact to it. Which it might do if bouncing around in a pocket or what not. I could be wrong but check it out. Don’t want anything giving you the smoke of death or anything. Smile

Awesome comparisons by the way.

I also picked up the S1A Cu after the S1 mini Cu I got from you and the S1 mini Ti I snatched up. Really liking the extra length of the AA light for my somewhat large and clumsy hands.

Take care my friend.

Todd
Thank you for the safety warning, and for introducing me to the Utorch, it’s been a real eye-opener. I will not run the Utorch S1 Mini NW, without the lens on it again :-).

The Utorch just landed in Texas_Ace’s mailbox today. Its getting an n219b 9080. I hope it works!:-)

Congrats on your Cu S1a, instant classic!

I had a titanium S Mini in my Shopping cart at illumn.com today but decided not to pull the trigger because S Mini have no low battery indicator.

So then i put an Olight S1 Mini in my cart instead.
My buy it now finger was twitching madly but I managed to quell it before it landed on the button. I did not want the Cool White model.

Code blacknovember worked for both lights. 30% off always tempts me.

I tend to buy more lights when I’m waiting for lights to get to me in the mail. My wallet thinks I need Real Therapy, not Real TiTherapy

Dont tell my wallet about the two other Utorch i ordered on flash sale. Theyre in the mail to Bali for Nichia swaps.

Im building a menage a trois Nichia Utorch
2000k, 3000k, 4000k

Wish the olights would play w Nichia, the olight UI is so much better.

Awesome, I bet that 219 will look phenomenal in that Utorch.

I understand about the wallet. I really need to slow down on my purchases. I only have 3 more coming in the mail and haven’t ordered anything lately. Although, I was looking at that Eagletac D25A with the 219 in it. Then again I really want a Klarus Mi7 Ti too. I don’t know.

Think I will behave myself for awhile.

Looking forward to some beam shots when you get those lights back. I hear TA is one of the best so i’m sure you won’t be disappointed.
