similarities Utorch S1 Mini, Klarus Mi1c, Olight Minis, and Sunwayman

jon_slider · February 27, 2018, 6:14pm

imo, all these lights are using parts from the same sources

Re: Utorch S1 Mini,
same model name “S1 Mini”, same timer and UI as 0light S1 Mini and 0Light S Mini,

same USB battery as 0Light S1 Mini and Klarus Mi1c (Fenix also puts their label on a USB 16340),

same fisheye/convex/aspheric lens as Klarus Mi1c and Sunwayman T16R

Same no High CRI as S Mini and Mi1c

Klarus Mi1c and 0Light S1 Mini have low battery indicator

does the uTorch S1 Mini have low battery indicator?

Of the lights mentioned, only the 0Light S1 Mini offers High CRI

I wish one of these was available with a Nichia!

They use Cree LEDs and they get the lenses from some company. And they don’t produce batteries.
They copy from each other

UTorch S1
Head and tube one pice

Klarus
Head and tube two pieces.

The UTorch has no red switch LED IMHO, I didn’t see one in the video.

You can rebuild normaly any UI
And the Olights S1 series was long time without a good clone.

I think if you disassemble the lights they are quite different.

thanks for your thoughts, and for making me aware of the Utorch light by posting in the 0light S Mini thread

I appreciate you pointing out that the UTorch S1 Mini lacks low battery indicator, that is a feature my 0light S Mini does not have either. The Klarus Mi1c does have low battery indicator. As does the 0light S1 Mini.

decisions… features, choices… oh my!

Youre welcome!

I guess the rechargeable USB batteries have a under voltage protection as most of the good protected ones.
I hope it is similar to this

The lamp can stop working, but you shouldn’t ruin the battery.

jon_slider · March 1, 2018, 6:46pm

yes, I really like the USB rechargeable LiIon, and yes, they have built in protection so are a good choice for unprotected lights like the ones in this thread.

Wow thanks for the very detailed table. How do you determine Nichia compatible?

jon_slider · May 17, 2018, 4:40pm

edited the feature list to correct the Ti S Mini is NW, and to show the LED types

Nichia compatibility is lacking for the Olight S Minis because the TIR is designed for the wider die XML2, though I made an exception for the Sunwayman that is also XML2, because it does not have a TIR. I did not mark the Olight S1 Mini as Nichia compatible not because of the TIR, which IS compatible, since the light uses an XP-G3, but because the Olight S1 Mini cannot be opened without damage. The ones marked Nichia compatible have bezels that unscrew easily, and use XP leds, that match the footprint of Nichias… At least, that was my thinking. Open to corrections.

fwiw, the N219b 9080 LEDs from Clemence are available again, for one last time. Anyone interested, this is your chance to stock up.
see

Great comparison, thanks. It would be even better if you included light dimensions and weights.

jimmy_yang · May 29, 2018, 12:35pm

However, the high CRI provided by 0Light S1 Mini is a tragedy.
Cree High_green-CRI

jon_slider · May 29, 2018, 5:29pm

Good idea
I dont want to take the time atm, but I can tell you that the Utorch S1 Mini weighs about 5 grams more (the weight of one USA 5cent coin), and is about 1/4” longer, than the Olight S1 Mini High CRI

I have a thread here with more info about both lights

I agree. I could tolerate the light with a Lee 1/2 minus green filter. But I sold it and bought some Utorch S1 Mini instead, because they can be modified to Nichia.

The Olight S1 Mini has high CRI Ra, but rather low CRI R9, the Saturated Red component.

there are more photos and info about the R9 of several high cri lights here

added Fenix E16, preliminary… I invite more accurate info, for example, should I also list a Cool White option (Fenix E16R), and does anyone know if the tailmagnet is removable, and if the beam is similar to the Olight S1 Mini?

Agro · September 19, 2018, 9:50pm

Size / weight data straight from manufacturers:
Olight S1 mini 21*54 mm, 43g
Olight S mini CU 21*54.5 mm, 54g
Olight S mini Ti 21*54.5 mm, 31.5g
Utorch S1 Mini 59.4*20.6 mm, 28g
Klarus Mi1C Alu 54.5*20.5mm, 27g
Klarus Mi1C Ti 54.5*20.5mm, 33.2g
Klarus Mi1C Cu 54.5*20.5mm, 56g
Klarus Mi1C HCI 54.5*20.5mm, 26g
Sunwayman T16R 59*26mm, 30.8g
MecArmy PT16 69*30mm, 45g
Fenix E16 51*21.1mm, 21g

Olight S1 Mini Al seems too heavy, maybe they include battery?
Also Klarus Mi1C weighs less in HICRI.

jon_slider · September 20, 2018, 12:28am

Thanks for your contribution!
I added the weights to the feature charts posted above also

I agree Olight S1 Mini weight is way overstated above
the Utorch S1 mini weight is understated above
I removed the lights I dont have from the list below, these are their actual weights on my scale:

these are empty weights, no battery, AND no clip. Posted clip weight separately, so people can add those in if desired. (I remove clips for personal preference, so clip weight is separate)
Olight S1 mini 21*54 mm, 21.2g clip +5.2g
Olight S mini CU 21*54.5 mm, 52.3g clip +3.2g
Olight S mini Ti 21*54.5 mm, 28.5g clip +3.2g
Utorch S1 Mini 59.4*20.6 mm, 30.5g clip +3.1g
MecArmy PT16 69*30mm, 54g

Agro · September 20, 2018, 12:36am

I think dimensions deserve a mention too. F.e. Sunwayman is quite large for its weight.

jon_slider · September 20, 2018, 12:56am

thanks for the reminder, updated the chart w weights, thanks for collecting the data

Slayer1 · September 20, 2018, 2:32am

Great info.

Agro · September 20, 2018, 7:19am

Maybe-correction: E16 probably doesn’t come with a TIR but with a lens-reflector hybrid. I doubt it’s narrow, but maybe…

jon_slider · September 20, 2018, 3:40pm

I believe the E16 does use a short TIR, but may be mistaken. Fenix calls it an “optical lens” and shows it compared to what I would call a TIR, hence I consider the E16 lens a short TIR.

As far as narrow or wide, my definition of a narrow beam includes the Olight S Mini and Olight S1 Mini. They are basically a wide hotspot, but not as wide as the spill on a conventional reflector beam. I call it narrow, because when I use an Olight as a headlamp, I have to move my head a lot, to keep the bright beam on whatever Im doing with my hands.

My only reference for the beam on the E16 is the German Video. It shows a very round beam, no hotspot, hence, I think TIR, similar to Olight beam.

By contrast the Aspheric lens of the Utorch S1 Mini, is a huge flood of even light. When used as a headlamp, I do not need to move my head, just my eyes, to be able to see everything in my hands, out to shoulder width, easily.

For my arms length headlamp use, a conventional reflector, such as on my Lumintop Tool, forces me to move my head constantly, to keep the hotspot aimed at whatever is in my hands. I do not like reflector beams for arms length. I dont like the Olight TIR any better. I consider both give me a narrow field of bright light at arms length.

these are just my thoughts, Im open to others perspective. Some people for example, might consider the beam from an Olight TIR to be “wide”, and it is certainly “wide-er” than the hotspot from my Tool, when shining across a room…

Here is an example of an Aspheric, then an Olight TIR, and a conventional reflector on a Tool.

the lights are, left to right, Utorch S1 Mini w Aspheric and 2000k E21A, stock Olight Ti S Mini w TIR and NW XM-L, Lumintop Tool w reflector and N219b 4500k 9080

Personally, Im very disappointed with the Tint of the Ti S Mini. I would sell that light for $40 shipped Conus, if anyone wants it, PM me.
