Size & Construction
This is a very small light https://i.imgur.com/aMdafMR.jpg 54.60mm in length https://i.imgur.com/3z8qTyb.jpg to be exact and 21.8mm in diameter to be exact. Weight came in at 1.55 ounces with battery and clip. It’s made of aluminium that is very nicely anodized a black finish with low gloss. The body has a nice texture on the battery tube and the tail cap has flat spots to help you unscrew it. The tailcap is also magnetic and decently strong. The head is ribbed. If I compare it to my Olight Smini here it’s identical in size.

This light breaks down into 3 major pieces https://i.imgur.com/MXWky4V.jpg, the bezel can be unscrewed with a lock ring pliers. There are springs on both sides of this light. The magnet in the tail can be easily removed (Just remove the spring) https://i.imgur.com/795TSUE.jpg The clip is removable and fully adjustable anywhere around the light. Overall it’s a fantastic clip for EDC. https://i.imgur.com/dqkBdyo.jpg

LED and modes
The LED in use in this light is a Cree XP-L HI V3 in cool white. https://i.imgur.com/TM2YsLP.jpg I didn’t observe any off colors in the beam. This light features 4 main modes and 2 flashing modes with soft mode changes in between each mode. There is no direct access High or Low mode. Mode spacing could be improved in my opinion. As you can see in the table https://i.imgur.com/FT1LoSl.jpg there is a big difference between high at 600lm and medium at 45lm. Low is listed at 10 lumens and moonlight is thankfully at 1lm. Strobe is at 600 and oddly SOS is only at 45 lumens. These were all with the 16340 battery. I would have liked to see another mode between High and medium, something like 150 or 200lm as I think it would be very useful.

On High mode I noticed the light flickers slightly at the beginning before it stabilizes. I tried to capture this on video but was unable to, it’s not very noticeable. This light also has a blink system used to show the battery capacity.

Lockout
There seems to be an error maybe due to translation in the manual about lockout mode. I found it hard to get the light out of lockout if I followed the manual until I figured it out. To activate lockout press and hold the button when the light is off, hold through moon light mode and the light will flash 3 times. If you push the button again the light flashes twice showing it’s locked. To unlock press the button 3 times quickly and the light is now unlocked.

Lens
This is a very floody light thanks to it’s drop style lens. https://i.imgur.com/7pxIX0F.jpg https://i.imgur.com/zpM0yY7.jpg It has no reflector https://i.imgur.com/NHQXve8.jpg to keep it as short as possible. I measured the lens at 16mm in diameter and 5mm tall. Personally I would prefer a TIR style reflector like what’s on the Olight Smini because I prefer that beam pattern for EDC uses.

Battery
This light does need a moderately high drain cell in order to get the full 600 lumens for more than a few seconds. Included is a Klarus branded USB rechargeable 16340 battery that's stated at 700mah. It has a microUSB https://i.imgur.com/3v83YXH.jpg connector built into the top of it. When recharging there is a Red LED on top and when it’s full it turns blue. I measured this battery recharging at 0.33A. I had no complaints with this battery. There is not room for an 18350 battery in this light. The light is compatible with standard CR123a cells as well.

Runtime Graph
Here is a graph of runtime I did on the included battery on a full charge. https://i.imgur.com/42JM2JT.png As you can see temperature regulation played a pretty big roll in the output of this light with the light stepping down as it got hot. I think an additional mode between high and medium would be a nice compromise between more useable light and heat.

EDC
As an EDC this is pretty darn great. I really like the captured pocket clip https://i.imgur.com/dqkBdyo.jpg that allows for very deep bezel up carry. https://i.imgur.com/MXWky4V.jpg It’s fully rotatable on the light and nicely accommodates jeans that have a larger seam at the top.There is a magnet in the tail that is strong enough to hold the light up but not much more than that.

Package
This looks like a perfect little stocking stuffer to me. It’s like it’s already wrapped up and with a bow. It’s a very nice presentation box. Inside you get 2 extra o rigns the manual and that's it.

Pro
* Good low lumen mode
* Very well constructed light with excellent anodizing
* Great in the pocket EDC ability, no issues with accidentally turning on.

Cons
* I am just not a big fan of the light output of the lens here. It’s too much a super even flood and has very harsh edges. I would have a more hot center allowing the light to be pointed.
* Mode spacing could be better. It needs something between High (600lm) and Medium (45lm)
* No USB cable included for recharging.
* There seems to be some translation issues in the included manual about lockout mode.

I have an Olight Smini in copper and really like it as an EDC light. It has a TIR style lens which makes a very useful wide beam with a hotter center. The Mi1c I thought would be very comparable and have the added features of a magnet in the tail cap, be lighter and a great clip but instead the super floody nature of the lens kind of turned me off. I used the light out one night when I was out photographing the sunset to navigate down some trails and out of Golden Gate park https://i.imgur.com/TSiTgGR.jpg. It did work for this but I wished I would've had my Reylight Ti-Lan I also had brought on my trip instead.. It was good for up close but further away the super even floody beam provided long shadows that made it hard to determine the trail. Part of this is due to the big difference in lumens between high (600) and medium (45).

In all fairness this isn’t a light to take on a hike. In more normal urban EDC use this light did better. It’s worked well to find the screw the went under a piece of furniture, to make sure the mailbox was empty at night, and to avoid spiders in the backyard. It’s clip is fantastic and it’s fantastic as an EDC. It’s lightweight and well built and rechargeable nearly anywhere. With the attractive box it would make a nice stocking stuffer too. Take a look at it on Bestlight.IO.

I found that the lens is a plastic and easily scratched when I open the bezel using pliers.

I have a plan to replace the lens with TIR but the bezel thread is quite deep. The Cu/Ti version (using TIR) has thinner bezel.

Thanks for posting this here. I just want to point out that the Copper and Titanium variants of this light use a normal reflector setup instead of that lens. Otherwise, they are functionally identical.

Just wanted to point that out so the lens doesn’t influence anyone’s purchasing decisions on the Cu/Ti version.

Thanks for posting. Was wondering the aspheric lens version looked like. I have the Cu version with the op reflector and have to say the beam is quite nice with a large hot spot and nice wide spill. Also, mine does not flicker on any mode.

The Copper and Titanium models have a different lens then the one I reviewed.

darn, just when I thought I did not need another light :slight_smile:

do you happen to have an S Mini to compare? curious about the beam shape differences

also curious to see a beam comparison of the Aluminum Mi1c (that has no OP reflector) next to a Cu or Ti model that does use an OP reflector.

If anybody has all 3, the two Mi1c plus an S Mini, please show the beams compared to each other… Which would you choose for indoor use?

I have both the S-Mini Cu and the Mi1C Cu. The hot spot on the S-Mini is larger although they both seem to have the same type of useful spill. The OP has a video on the Aluminum version of the Mi1C with the aspheric lens.

thanks for the info
would love to see the beams side by side, or one after the other on the same subject

Ive seen several pics and vids of the aluminum Mi1c, but not in direct comparison to the S Mini and the Ti/Cu Mi1c

this image makes the aluminum Mi1c look like the wrong tool for outdoors:

My application is mainly indoors, close range, for example shining on the floor, using the lowest level, to go to the bathroom… inside a Camper to illuminate the stove, and food… or also to shine on the wall in the living room… I really like the S Mini beam for those uses… I do not notice any spill to the S Mini Beam, to me it looks like all one large hotspot…

thanks for the informative review

if anyone here owns both an Mi1C aluminum and or Copper or Ti, and an S Mini, could you post side by side beam shots so I can see the difference in size. the intended use is close range indoors, so shining on a wall in a house from 3-5 feet away, at about 10-50 lumens, would be helpful (no interest in turbo for my application)

What is the parasitic drain on this light. The Mi7 was horrible, ruined three batteries in three lights.

define “Ruined”
Were they protected LiIon?

I don’t know the parasitic drain, but Liquidretro probably does, maybe PM him?

fwiw, here is another review by liquidretro, of a similar light, and he mentions the parasitic drain amount
https://www.reddit.com/r/flashlight/comments/7ivs45/olight_s1_mini_baton_cw_written_with_photos/

Fwiw these lights do not have built in over discharge shutoff circuits in the light, so you should not use unprotected LiIon cells….

The USB rechargeable LiIon that comes with the Mi1c has built in protection and it will shut itself off to prevent over discharge.

Zero voltage on batteries, had another one that had a protected cell in it and that battery is OK. Not keen on having to use proprietary(or protected) batteries for a light to operate without ruining batteries.

With all due respect, protected batteries are not proprietary, they are safer and typical…

When a protected battery protection is triggered from discharging below whatever the trigger point is, such as 2.7 V, the battery will read zero voltage. That just means it needs to be put on the charger.

Zero voltage on a protected cell does not mean that it is ruined

I was shocked the first time it happened to me but the battery recharged just fine, it was just the protection circuit.

Did you try putting your zero voltage batteries on the charger. Do you know for a fact they are not protected batteries?

Proprietary as in battery with built in USB hookup. The ruined batteries were Efest purple, unprotected. They were put on a charger and would not charge.

Unfortunately, aluminium version can’t get beam profile as nice as yours.
I know my pic is too close to the wall but I hope you’d see how the beam profile look like.
