Imalent MS12 2019 version

Imalent MS12 review (2019 version)


Imalent shook the flashlight community with the announcement of the Imalent MS12. The previous brightest flashlight was the Acebeam X80GT with 32250 Lumens, and Imalent just almost doubled that number with 53,000 Lumens! Therefore it is mentioned in our brightest flashlights list!

This is my second Imalent flashlight review in 5 years. My first was the SA04 with an LCD display. Back in the day when Imalent entered the flashlight market with LCD displays! Fast forward 5 years and now we have a flashlight that is claimed to reach 53,000 lumens.

It’s not going to be your EDC, nor your average Bedside light. The MS12 is for illuminating your local baseball stadium! So they haven’t included your favorite lanyard.

What you’ll get:

  • Imalent MS12 flashlight
  • Nice quality storage box
  • Shoulder strap
  • Spare O-rings
  • Charge adapter

Handling of the Imalent MS12

Fortunately, Imalent included a shoulder strap with the Imalent MS12! That’s how I would start this section. The Imalent isn’t just high on the lumen scale, it’s also high on the weight scale. Most of the weight is in the head, and therefore it is tiring for your index finger to balance the flashlight with its front-heavy weight! The included carry strap is, therefore, no luxury but a necessity! It’s fun playing with it, but within a couple of minutes, you are feeling your wrist and index finger due to the unbalanced weight. Therefore I’d recommend using the shoulder strap if you are planning on using it longer than just a few minutes.

Another thing I noticed during my testing outdoors was the following: When you use the carry strap, it’s not very difficult to find the switch, especially when it’s cold outside. But when you don’t use the strap and you grab the flashlight, it is pretty difficult to find the switch! I hope they will improve that on future models!

Tail stand?

  • Yes, it can, but it’s better to put it with the head pointing downwards so you can use the sidelights.

Build Quality and Anodizing 

The build quality and anodization are good. The only problem I see is the should strap attachment. Even after only using the shoulder strap for 5 minutes the anodization was damaged. If you want to keep your MS12 in pristine condition on your shelves. no problem.. if you start using it outdoors… just know you’ll damage the anodization and even the aluminum itself, both on the front as well as on the rear. See the pictures below for some close-ups.

On the front side, you attach it to the bezel; on the rear, you attach it to the battery tube. I’ve looked all around the light but couldn’t find anything wrong. Although it’s not the most beautiful light. but rather futuristic.. lol.

TIP: If you care about the damage from the shoulder strap, you can use Heat Shrink Tubing. This way you can have an extra bit of protection to not damage your high-lumen beast!

Threads and O-rings

Both threads and o-rings came lubed. The body screws into the head and uses 2 O-rings to keep water from entering the body. I don’t want to test this, but I’m not 100% sure it can withstand water..claiming IPX8 the head, on the other hand, is open so you can see the fan moving around. The fan turns on when the head reaches 55 degrees Celsius (131 degrees Fahrenheit)

You’ll get an extra pair of O-rings in case you need to replace the current O-rings.

Imalent MS 12 LEDs, Lens, Bezel and Reflector

1 XHP 70 not enough? How about adding 12?
The Imalent MS12 uses 12 CREE XHP 70 LEDs to maximize output. The reason for choosing XHP70 over the newer XHP70.2 is unknown. That being said, I would argue that you wouldn’t be able to notice the difference in output with your own eyes! Anything passed 10K or 25K becomes more difficult to notice. So a jump from 40000 to 50000 would be much harder to notice than a jump from let’s say 400 to 500 lumens.

Besides the 12 XHP70 LEDs, the MS12 also uses 6 white sidelights that a long press can activate. I can see this being very useful while camping or just carrying the light around. It’s hard to measure lumens, but it’s definitely at least 10 lumens from each of the 6 sidelights. Please check out the UI section to read more.

The bezel doesn’t budge when you try to unscrew it by hand. It has holes to attach your favorite keychain (LOL) or the included carry-strap. It’s probably aluminum—definitely not Stainless stell.

All reflectors are Orange Peel with 11 in a circle and 1 XHP70 in the middle. This layout doesn’t really help to reach far, but it’s a nice spread of lumens across the board. Check out the beam shots at the bottom of this page.

The Lens is clear but has some kind of coating, maybe UV/AR coating?

Size compared to BLF Q8, Acebeam K65, Astrolux MF04 (Imalent MS12), and Lumintop BLF GT

5 big flashlights side by side

User Interface:

The Imalent MS12 uses a sophisticated User Interface, using only 1 electronic switch.

Modes: 8 with mfg lumens.

  1. Low (300)
  2. Middle low (900)
  3. Middle I (1900)
  4. Middle II (3800)
  5. High I (7500)
  6. High II (15000)
  7. High III (30000)
  8. Turbo (53000)

From OFF:

  • Press and Hold: Activate the 6 sidelights
  • Single-click: last memorized output
  • Double click: Turbo output
  • Triple-click: Lockout mode (the red sidelights will blink twice to indicate the lock-out activation)
  • 4x click: Activate Fan

From ON:

  • Press and Hold: Change output from Low to High
  • Single-click: Turn Off
  • Double click: Turbo output
  • Triple-click: nothing
  • 4 clicks: nothing
  • 5-10 clicks: Turn Off

Side Lights:

When the light is activated, the 6 sidelights will turn green. These indicate the battery level. But when the main LEDs are off, you can use the sidelights to turn white. Simply press and hold the side switch from Off to enter the side lights. Single clicks will run the modes from High – Medium – Low output.

Great for use as a locator as well as some 360-degree light while camping / in your tent.

Low battery warning:

The 6 sidelights will turn red when the overall voltage drops to 11.8 Volts. At 11 Volts the red sidelights will start flashing.


It’s not in the main mode group, but you can enter Strobe mode by a double click from Turbo! There are no other blinky modes like beacon or SOS.

Lock-out mode:

You can enter this mode by clicking 3 times when the light is off. The red sidelights will blink twice to indicate the lock out mode is activated. When you do another 3 clicks the green sidelights will blink twice to indicate the lockout mode is deactivated.


I couldn’t detect any, except for the strobe mode. Lol.

Batteries and charging:

The Imalent MS12 comes with a battery pack that can be replaced but you can’t charge the cells individually, fortunately, because when having 8 pieces of batteries, you need to be careful to keep them together and use them only as a set. The battery pack includes 8*20700 batteries for high capacity and High Drain.

It comes with a dedicated charge adapter; mine came with a UK plug since I bought mine on So if you are in Europe make sure you order it with the correct adapter, and if you are in the US, this doesn’t apply to you, except if you order it from overseas! Make sure you order one with the correct plug. It isn’t very critical since you can just buy a cheap adapter if you order the wrong one.

Charging took me about 5 hours, while the documentation mentions a charge time of 4 hours and 38 minutes, so the charge time may vary. Another thing I noticed is that you can hear a high-pitched sound while the battery pack is charging.

TIP: Charge the battery pack when you see the sidelights turning red instead of waiting till they are flashing.. to increase the battery cycle life.


My integrated Sphere only measures up till about 4000 Lumens, and anything above this is difficult to measure consistently. I tried using a Neutral Density filter that I use for my Canon DSLR Camera, but the numbers didn’t add up. Tests were done with the Hagner E4-X lux meter.

Lumens measurements vs (MFG):

  1. Low: 309 (300)
  2. Middle low: 550 (900)
  3. Middle I: 798 (1900)
  4. Middle II: 1114 (3800)
  5. High I: 2007 (7500)
  6. High II: N/A (15000)
  7. High III: N/A (30000)
  8. Turbo: N/A (53000)


I usually don’t intend to do runtime tests with the powerful flashlights since they can actually damage (burn) the box I use for these tests. (It is just a cardboard box with some holes so I can see the light is still on). But its too small to use with anything above 5000 lumens or so. because of the possibility to start a fire.

After 2.5 minutes the fan turns on and the light starts to drop output. Within a few minutes, it’s too hot to touch! Be careful with this barn burner. LOL The following runtime is in Turbo mode.

The runtime is 70 minutes. Although it can run for about 80+ minutes, the batteries will be very low, or even too low. So make sure you’ll turn it off when the red indicator LEDs start blinking.

Low Voltage Warning

When the battery runs low you’ll notice that the 6 side switches will start blinking red! Now its time to turn the light off, you don’t want to damage the cells or anything! Even Acebeam has this problem. The light just won’t turn off automatically and the batteries could be discharged too deeply. This runtime might have been already on the low or too low….


Since this light is such a beast I have to be careful measuring the throw in our garden. The measurement is taken at a 10-meter distance.

  • Total Throw measured at 10 meters: 203,000 cd, so roughly 200Kcd


Overall conclusion


  1. Extremely bright
  2. Extremely bright
  3. Extremely bright… lol, had to type that 3 times in order to fully express myself :–)
  4. Pretty Simple UI
  5. Built-in fan for cooling
  6. Including 8*20700 high amp battery pack
  7. Built-in charging, so no need to have a dedicated charger


  1. Not cheap
  2. Carry strap damages anodization when attached
  3. Built in fan is noisy
  4. The switch is hard to find in the dark

Overall Rating: 5 stars ☆☆☆☆☆ Very good

The Imalent MS12 is a beast. The UI is rather simple, and the price tag is high, but you’ll get many photons back.
