The light was supplied by Banggood (link is external), no compensation other than the light itself was received for this review
This light is a pre production sample, there are futher improvements for the final light
The price can be lowered with a coupon here
This is my 4. light that was supplied by Banggood for a review, I am honest and will judge the light as it is with its pros and cons

There are some errors in the original specs
- the Nichia are neutral white, while they are described as warm white
- Sumsang Q30, Utilises, aluminium, Nicha and anodising spelled wrong
- some spaces are missing after the comma
The parcel arrived after 11 days shipping with to Germany which is very fast from China.
Package and content:
The lights box came packed well with a plenty wrap around and in a plastic bag
The light comes in a solid card box
The box has a compartment for the light and a bag with small parts
It comes with 2 spare o-rings, lanyard, thread adapter and manual, but in my case the manual is missing
Photos of the light
Comparism and teardown:
Size compared to other 18650 lights, I do not own SRK size lights, the MF-01 is a bit bigger than them as the head has a lager diameter than the battery tube
Beam color is neutral around 5000K for the Nichia 219C model, the Nichia has a nice uniform beam and color rendering is great
The LEDs are reflowed ok could be better and the MCPCB is perfectly flat, but not polished
Unfortunately on my sample there was a little solder under the LED board and the heat paste was not evenly spread
and some small dust particles on the domes of some LEDs, the whole MCPCB is dirty
from left to right the lights get warmer, picture taken @5000K camera setting
left Astrolux S42 Nichia 219C 5000K, Astrolux MF-01 Nichia 5000K, XPL HD 1A 6500K
The LEDs in this light are available XP-G3 and Nichia 219C
The light can be taken apart completely, nothing is glued
The light has a massive tail cap with holes for a lanyard, and tail stands rock solid
The head has a diameter of 72mm and 62mm visible of the TIR optic
The battery carrier comes with a warning not to put in the batteries in reverse polarity
The driver can't be pulled out easily, the LED leads have to be unsoldered
The light uses 3 separate buck regulators
The light can be physical locked out by twisting the tail cap or head about a 1/2 turn
The Head
the TIR is a medium throw, gives a nice uniform beam with some spill
the Nichia LEDs fit in nicely and the majority of them seem all to be centered perfectly
The slave board for the switch has also a green and red LED
The shelf is 2mm thick and the 1.5mm thick copper MCPCB does a good job spreading the heat, on Turbo the head gets hot quick, so the thermal path is well if the heat paste is applied better than in my sample
The MCPCB is s true copper DTP, the back of it is gold plated
The MCPCBs back is perfectly flat
The light should be waterproof, but I wish the heads o-ring would be pushed a little harder
The lens is AR coated glass
I would like to see the TIR attached to the lens with optical glue to get more OTF lumens
Tube and Tail
The tail cap is solid and fully anodized there is no battery connection
the tube inner diameter is 45mm even my double heat shrink tube unprotected batteries have some play
The tube threads are triangular cut on both sides, the tube has 2 o-rings and both sides is lubed for water tightness, the amount of lubricant is good
square cut would be nicer, but all Astrolux lights have triangular with a flat top
Driver and Battery
The light has no visible PWM in any mode, even falling water drops show nothing
The light has a lot mass to absorb heat, in turbo mode on a high drain cells it gets hot quickly, in High the temperature takes quite some time to get hot
The 2S/2P battery carrier is build rock solid and can be inserted both ways
The battery carrier can be used in both directions, but it's better to put the side where the battery positive and negative is separated towards the driver to avoid the current flowing through the brass rods connecting both sides
The light is build for unprotected batteries, protected or button top unprotected won't fit, the ones I have with a 2mm brass button fit barely
On the left the one with the brass button and on the right a flat top battery
the springs get fully compressed with an unprotected brass button cell, so their resistance is very low
The mode spacing is OK, the moonlight has about 3-5 lumens, the high could be a little less
Current measurement with 4 Samsung 18650-30Q fully charged and rested at 4.15V
The carrier is modified to measure the current with a 0.5mm² wire, so the measurement might not as precise as in the assembled light
Tail current for modes
Moon 0.125W 8.3V and 15mA
This is not really accurate with the clampmeter, I guess the real current is lower
Low 6.4W 8.25V and 0.78A
High 57.4W 8V and 7.17A
Turbo 120W 7.66V and 15.67A
At 3.4V per cell the light does switch the indicator LED in the side switch to red to show low battery warning
At 2.9V the indicator LED blinks to show critical battery level
The light shuts down at 2.7V per cell, for my liking too low for a 2S light if the batteries might be not perfectly matched
Below that voltage it shuts down and you can't turn on the light again
The light pulls in the breathing mode 0.5-0.7mA from the battery
the breathing mode stops at 2.7V per cell to prevent over discharge
When the light is locked out with side switch it pulls about 39uA
Modding:
First thing was to bypass the copper alloy Spring on the driver
I sanded MCPCB to remove the solder residue and get a polished surface
Added a wire to the LED- to shelf, I could have increased the positive gauge, but I didn't
You can also see that I cut threads in the TIR holes to screw down the MCPCB to spread the paste better, the 3 screws on the outer ring are nice but in the middle of the MCPCB they would be more effective

User Interface
The light has 4 modes including moonlight
Too bad my sample misses the manual, but so far I got it sorted out
Connect battery with light it enters breathing mode.
From breathing mode
- 0.5s long press locks out the light
- short press to turn on the light last mode memory
- double press enters strobe
While in strobe any short press advances to SOS, then beacon, another short press turns the light off
In any mode a 0.5s press turns the light off
I like the user interface of the UT01 more than the one here, but it's better than the last Astrolux S42 light.
Conclusion
Positive:
- mechanical very good production and engineering
- very solid head, DTP MCPCB screwed on the 2mm shelf
- Nichia LEDs has a nice neutral white with great color rendering
- AR coated glass lens
- good uniform beam, some throw by the shear amount of light on turbo
- nice low moonlight
- proper LVP and low battery warnings
- low resistance copper alloy springs
Neutral:
- triangular cut threads, square cut would be nicer
- 18650 battery carrier fits only unprotected flat top batteries
- the UI is a lot better than on the S42, but still not like many flashaholics want it, one like Utorchs UT-01 would have been nice
- mode spacing is not optimal and a light with this amount of lumens need an option to switch to more modes
Negative:
- no reverse polarity protection, you get a big notice in the light to avoid wrong polarity
- Quality management is not good: missing manual and solder spot below the MCPCB and not good applied heat paste
