“REVIEW” - Imalent MS18 – 18 XHP70.2 – 100.000 Lumens – Hot & Bright!

Hi BLF!

This is my review of the Imalent MS18 flashlight, which I believe is the brightest flashlight commercially available…currently!! It nickname is “Ambassador or Light” but I just call it “WOOOOW”!!! Shocked

The flashlight was sent for review by Imalent, after being contacted by Imalent_official. My compromise was to make an unbiased review and that’s what intend to do here, with no obligation to make a positive or negative review. I had no other compensation than the light and its accessories, that I can keep for myself. Thanks Imalent for this opportunity:THUMBS-UP:

Currently the MS18 is at sale with a drop price [432,99€]. Party Party Party

Extracted from lock ‘s review:

With a simple calculation, considering the 3.6V battery pack and its 92.2Wh (3.6×3200×8 = 92160mWh = 92.2Wh) it turns out that the batteries have a capacity of 3200mAh. But being 21700 Samsung 40T 4000mAh, there must be a mistake
With these cells, in the 8P configuration, the battery pack would have to carry the word 3.6V 115.2Wh. I therefore asked for explanations directly from Imalent who promptly replied, confirming the accuracy of my calculations and therefore the battery pack is actually 115.2Wh.

————————————————————————————

FLASHLIGHT & ACCESSORIES

Well, let’s start from the beginning!
The Imalent MS18 arrives in a box, a big box made of a thick and tough material, although its’ coating seems leather or, at least, some smooth fabric. It is closed through 2 buckles and it also has a carrying handle. In the front there is information about the flashlight (including the mention to the 5 year warranty) and the back has only the “low-relief” inscription of “IMALENT” in the lower part.

Front & Back

Buckles & Handle

Inside, we find a 3 layer block of foam where the flashlight and accessories are stored. We find:
- Imalent MS18
- shoulder strap
- user manual
- charger
- 2 spare o-rings
- silica gel Silly

There are also 2 stickers, one with a warning to remove the “battery insulator” (that prevents the contact between the battery tube and the spring/head contacts), and another with the Serial Number.

Between the top of the box and the flashlight, there is a thick black foam pad to prevent movement and eventual damage to the flashlight.

And here you can see the items that are carried inside!

Let’s start from the flashlight, and some general appreciation:
- It is big and heavy! The longest, the largest and the heaviest I’ve ever had or handled.

- I can’t close my hand when grabbing it by the tube… Small hands or large tube? Silly

- Handling it, one feels “powerfull”, in the way that it feels like it will obliterate any darkness when lit up!

- The are no evident machining flaws, the anodizing is smooth and without chips or aggressive parts

——————————-

Going more descriptive:

- the flashlight is composed by 2 main parts: head and battery tube

- there is one small detachable disc on the tail (tail cover), to allow access to the charging port

- all the flashlight is anodized in black, apart from the bezel, the shoulder strap “hoop” and the “tail cover” which are grey, and the switch (bare stainless steel)

- the AR Coated Glass Lens arrived covered by a plastic protection that must be removed before use; it prevents some fingerprints to land on the glass before using the light

- between the lens and the reflector there is a white/transparent o-ring to help on water/dust proofing

- above the 18 Cree XHP70.2 Cool White LEDs there is an Orange Peel (OP) reflector, eventually to avoid an even more pronounced tint shift that these LEDs produce (at least in the “somewhat” lower levels)

- in the head there are cooling fins and 2 fans (1 in, 1 out) to allow cooling down this massive beast of heat and light; it can be seen a copper structure inside, that acts like a radiator/heatsink

- in the “upper side” of the flashlight there is the e-switch, the OLED screen, the hoop for the shoulder strap and the HOT engraving

- the switch is responsive to the touch/clicks/press & hold, despite sometimes it seems like it gets inclined and some clicks sound like “in false” I tried it with work gloves and it worked well

- the OLED screen shows different type of information about the flashlight (see below) and it normally can be seen well (unless you turn the flashlight ON in turbo against a white wall less than 1m distance… then the brightness blinds you and the screen can’t be seen properly Facepalm )

- the hoop for the shoulder strap is screwed in into the head structure, and I didn’t try to remove it

- the fans are held in place by hex screws and I also didn’t try to take it out

- as mentioned, between the battery tube and the head there is a thick plastic insulator that must be removed before use in order to turn the flashlight ON; it prevents accidental activations while storing/shipping the flashlight

- the battery tube needs to be screwed in REALLY REALLY TIGHT so that it makes contact with the head and spring I needed to put the head of the MS18 against a sofa cover in order to rotate it and make it REALLY REALLY TIGHT, by using some force

- the spring is “doubled”, which means that it has a thicker spring outside and a bit thinner one, on the inside

- around the spring there is a structural black plastic insulator (structural) and then there is a driver’s brass ring , that will make contact with the battery tube’s brass ring

- the battery tube has a similar structure, with a flat central part (brass), that will make contact with the spring on the head

- the “structural black plastic insulator” on the battery tube says…*DO NOT DISASSEMBLE THE BATTERY*

- the threads of the tube are square and abundantly lubricated

- there is a sealing o-ring below the threads

- the tube knurling is not deep not aggressive, its is “square-shapped” alternating with some flat “stripes” from the bottom to the top of the tube

- the grip is good, but maybe with some sweaty or oily hands it can slip a little bit [no issues with work gloves]

- the detachable disc on the tail (tail cover) has several functions:
a) protects the charging port
b) allows the MS18 to have a flat bottom to tailstand
c) acts as single or multiple hoop for the shoulder stap

- it also has engraved Battery Pack MRB217B 3.6V 92.2Wh and other information (model, RoHS…) [BTW, I guess it may be stainless steel, but I am not sure :x] [see above information about the battery pack]

- the charging port is on the bottom of the battery tube, and it has some transparent parts that allow seeing the RED colour (charging) or GREEN colour (charged) regarding the charging status

- the charging port works with the included AC/DC power adapter/charger, not with any type of USB charging

——————————-

Let’s take a look at the Imalent MS18:

with the thick plastic insulator to prevent contact between the tube and head

——————————-

HEAD

BEZEL & SPRING

LENS PROTECTOR

LEDs & REFLECTOR

4 VIEWS ON THE FLASHLIGHT

Some “protruding parts”: hoop, switch and fans’ plastic structure

——————————-

Let’s check the information provided by the OLED Screen. Besides the output levels, it can show:

SWITCH INDICATOR LIGHT
This allows to see where the switch is placed. If left ON, this indicator light will turn itself OFF after 3 hours. [ due to this it will not act as “lighted switch” as other lights have ]

De/Activation: with the flashlight unlocked and OFF, press the switch for 2 seconds

LOCK/UNLOCK
To lock and unlock the flashlight we must click 5 times the switch while the flashlight is OFF.
If the flashlight is locked, the “padlock” will appear closed when pressing/clicking the switch.
When it gets unlocked, the “padlock” will appear open.

BATTERY
With the flashlight ON or OFF (always unlocked), we can see the battery status and level.
To check it we must click 3 times while ON or OFF.

It can also show when the battery needs to be charged, by showing an “empty battery”. According to specs, at 11.6V this symbol will blink 10 times per minute as a “YOU NEED TO CHARGE ME” reminder Wink

However, it may appear before this battery level is reached, specially if the battery is already low and it is being used in middle or high levels (above 10.000 lumens)

FAN
The fans of the flashlight activate immediately when the flashlight is turned ON at the 22.000 lumens level or above (not below).

However, they can be also activated from OFF, which is a good way to cool the flashlight down after some use.
For that, we need to 4 clicks on the switch to activate them and 1 click to turn them OFF.

HOT
Last but not least, considering the massive amount of heat generated by this flashlight, there is a HOT symbol that will blink 8 times per 30 seconds when the flashlight reaches the internal temperature of 70ºC.
More on the thermal control bellow.

——————————-

TUBE

Now, lets take a look the battery tube.
The knurling pattern mentioned above and also how tall is the structure that fits the head of the flashlight.

As for the contacts part, see that there is a small “gap” between the brass and the aluminium (I guess that it acts as a safety distance) and also the part that makes contact with the driver.

And now the bottom, namely the tail cover, the charging port, the “flaps” on the tail and the threads on the charging port

Some details on the disc, given its importance when attaching the shoulder strap. See that it has different holes where the clasps can be attached to allow different “styles” as we’ll see below.

——————————-

DIMMENSIONS & WEIGHT
I’ve said that the MS18 is big and heavy, but how much?

SIZE

TUBE SIZE

WEIGHT
See that the head is really heavy, being more than half of the total weight Shocked

BOX WEIGHT
And because this is not an ordinary box, let’s just see how heavy it gets to carry the whole package Silly

——————————-

ACCESSORIES

And now let’s check what comes in the box with the Imalent MS18!

O-RINGS
Two of them, because one may not be enough and this light needs it to prevent water from entering the battery tube /driver. Well, at least from their junction…

CHARGER
I got the EU version of plug, of course. I won’t enter in details about it , just that it is an AC/DC power adapter/charger, capable of 19V-24V / 2A (OUTPUT) and 100-240V 50-60Hz 1.5A max (INPUT).

It is supposed to charge the MS18 battery pack in 4h25m. The battery pack is constituted by 8×21700 batteries.

The charger plugs have a plastic protection.

SHOULDER STRAP
This is a great and very useful accessory – I must say – to carry this flashlight!
Given the size and weight of the MS18, the shoulder strap, that is adjustable, that has 2 clasps (1 on each tip) and a pad to give comfort in the shoulder, is a must-have accessory.

It can be attached to the hoop in head + disc on the tail, or only on the tail.

It allows different ways of carrying and holding the flashlight that I tried to show in the photos below.

USER MANUAL
Well, most of the people don’t pay attention to the User Manual. I do and I always recommend people to read them because, well, they have important information.

That is the case of the MS18 manual which is written in 7 languages (English, Chinese, Japanese, Korean, Arabic, German, Italian).

This manual has many and useful information about the specs and the functioning of the flashlight. Below you find some shots of it so that you can read. I will not talk about all the points, people must read and draw their conclusions Wink

General overview

Click to see large images!

————————————————————————————

FLASHLIGHT FUNCTIONING

CHARGING
As mentioned above, charging the flashlight should take around 4h25minutes.
The flashlight should be charged when reaching the 11.6V (when the “empty battery” symbols starts blinking on the OLED screen) and it will stop around 16.5V (more of less)
.
When charging, the led indicator in the tail will be RED.
When charged, the led indicator in the tail will be GREEN.

The charging status/level can always be confirmed through the 3 clicks in the switch from OFF or ON.

If the plug is not connected correctly, the battery will stop charging

——————————-

INTELLIGENT THERMAL CONTROL

1) As advanced above, when the MS18 reaches an internal temperature of 70ºC, the HOT symbol will blink in the OLED screen and it will – supposedly – activate the fans.

ChibiM has reported an issue with the flashlight getting too hot (scorching) and the fans didn’t activate. See more information in this thread: https://budgetlightforum.com/node/79426

I’ve tested the flashlight for around 25 minutes on 10.000 lumens level (battery was at around 12-13V, so it was not full) and it didn’t go above 44ºC, being more than OK to handle it and grab it by the head without burning skin. Maybe with full battery this could be different.

2) According to specs, if the MCPCB reaches 110ºC the output will decrease from a higher level to 25.000 lumens so that a safe use can be ensured and prevent extreme overheating.

I did not conduce a test on this. I can tell, though, that after using the flashlight outside (for beamshot purposes) on the higher levels for continued periods, it got REALLY REALLY HOT. I turned the flashlight OFF and turned the fans ON.

Also, after using it for a while on max, there is some “steam” below the lens that tends to disappear with time and cooling. I am not sure what is this steam, but maybe it is due to solder or thermal paste heating, I don’t know.

3) The fans will only activate automatically when the light I turned ON in 22.000 lumens or above.

If this is true, the test and overheating that ChibiM got on his MS18 may be a consequence of this “system” that only activates if the flashlight is purposedly activated in such higher levels, and not only when the body/components are already hot. This seems also to be contradictory to the 1) above. Further tests need to be done to ascertain these situations and give a veredict on the safety of the thermal control.

——————————-

USER INTEFACE

The Imalent MS18 has a simple UI with some nuances.

For me, unfortunately is not a perfect UI, specially given it is a high power flashlight. Why? Because we cannot force it to start on the lowest level if needed, so we can blast our face (or someone’s accidentally)!

The MS18 will memorize any of the last used regular modes (not Turbo nor Strobe).

How it works:

- Turn ON / OFF: single click [from any mode or level]

- Change modes: press & hold to advance in the levels from Low > Middle Low > Middle I > Middle II > High I > High II > High III > Low…

- Access Turbo: double click from ON or OFF

- Access Strobe: from Turbo, double click

- Check battery level: from On or OFF, 3 clicks

- Activate Fans: from OFF, 4 clicks

- Lock/Unlock: from OFF, 5 clicks

- Activate Switch Indicator: from OFF, press & hold 2 seconds

——————————-

OUTPUT & RUNTIME

First thing to be said is: this is a high power flashlight. So, despit it produces a huge amount of lumens, it will not hang on at those levels for a long period of time, specially because it also creates a massive amount of heat.

In this way, the higher levels will attain the expected higher outputs for some minutes or seconds, and they will decrease after to protect the light and, hopefully, the users. Never leave this flashlight ON unattended!!!

Low Middle Low Middle I Middle II High I High II High III Turbo *Strobe
Output 700 lm 2000 lm 5000 lm 10.000 lm 22.000 lm 30.000 lm > 25.000 lm 60.000 lm > 25.000 lm 100.000lm > 25.000 lm 100.000 lm
Runtime 14h52m 9h15m 6h50m 3h40m 67m 3.8m + 60m 70s+55m 60s+52m NA

Here’s the flashlight levels as show by the OLED Screen:

————————————————————————————

SIZE COMPARISON

Well, and now…that ridiculous thing to do with the Imalent MS18 and many other flashlights (at leas those I have) Facepalm Big Smile

Imalent MS18 vs Wuben T70 > Amutorch AM30 > Fireflies ROT66 GEN2 > Emisar D4

BTW, these are the flashlights that I used in the beamshot comparisons below and in the video!

Vs Wuben T70

Vs Fireflies ROT66 GEN2

BOTH (Wuben T70 & Fireflies ROT66 GEN2)
They are still powerless Silly

Vs Amutorch AM30

Vs Lumintop GT Nano (LOL)

————————————————————————————

BEAMSHOTS

And now the most interesting part of getting the Imalent MS18 flashlight and…well, trying to compare other lights to it Big Smile

It is just absurd, honestly! The lights I chose are probably the most powerfull I have (stock lights) only missing here the Astrolux EC03.

Seeing the D4 or the ROT66, which are “hot rod” flashlights, being completely obliterated is something that impresses Shocked

But, check the photos below. The order is as follows (sorry, no identification on each one, but you’ll perceive which is which):

Emisar D4 > Fireflies ROT66 GEN2 > Amutorch AM30 > Wuben T70 > Imalent MS18

And now the “solos” of the MS18, ‘cause it deserves a place of its’ own. ( sorry, the photos, always lose some quality to make GIFs, but I guess you’ll know what I mean by the WOOOOW light )!!

————————————————————————————

OVERAL APPRECIATION

Well, this is the part where I spill the beans! The goods and the not so good ones!

WHAT I LIKE:

- the overall quality, flawless machining, the good quality of the flashlight in general

- the WOW factor that this flashlight provokes, in enthusiasts an non-enthusiasts

- the real tremendous range that this flashlight allows to reach, with its’ floody but also long distance range beam

- the shortcut to Turbo (and no Strobe on the main cycle Big Smile )

- the fact that the fans can be activated independently whenever the flashlight is OFF to provoke active cooling

- the locking function, as we don’t want an accidental activation of this light

- the battery indication from OFF, so that we know when to charge, because the flashlight levels couldn’t be checked in other ways

- tailstanding capability (even if the lowest level is 700lumens, it will certainly be useful to be used as “candle” in some situations :D)

- shoulder strap and multiple ways to carry the flashlight

- the information provided by the User Manual (despite some imprecisions)

- the 5 year warranty!!

- the carrying case! Just because Big Smile

————————————-

WHAT I SEE AS NOT SO POSITIVE ASPECTS:

- the price, because this is an extremely expensive flashlight, despite being the most powerful commercially available at the moment

- the size and weight, which are massive for continuous use, either with or without shoulder strap, and also for handling, etc;

- being a flashlight that can be used for search and rescue, I guess it could be suitable for a tripod mounting, by having a screw incorporated

- the impossibility to force it to start it on the lowest level (700Lumens) to avoid a blast of light on the eyes when turning it on after a 60.000 lumens use Facepalm

- the massive amount of heat generated and the eventual fail in the fans to activate if the light is hot but not set at 22.000lumens or above (further info is needed to verify this)

- the CW option for the LEDs, but in the “Lumens War” the most powerful wins, not the most beautifull or nicest to the eyes

- the impossibility to change batteries by ourselves, having to buy a pack from the brand, if needed (in this case, I assume it would be good that they could be easily replaceable)

- the “not” waterproofness or “dustproofness”, given that the flashlight has those fins/holes and the fans for cooling and heatsinking; of course, it can be used in some environments, but not in heavy rain or dusty environments, which is somewhat limiting

- this is also a concern regarding the tail cover and charging port, which needs to be well tightened and secure (specially after using the shoulder strap attached to it)

- the switch sometimes assumes clicks differently from what we did, not always, but sometimes

All said and done, this is a unique flashlight, with some tradeoffs, but unique and it is still to be born the one that attains what this attained !!!

————————————————————————————

And this is it!

This is my review of the Imalent MS18. I want to thank again to Imalent for this opportunity to review this flashlight and I hope I could clarify and portray what this light does and what is it about.

If you have questions or comments leave them below.

I also did some videos too, to show the Imalent MS18 flashlight and to show what it does outdoor, with full power on! Shocked

This is video showing some beamshots. I compared it with Emisar D4 > Fireflies ROT66 Gen II > Amutorch AM30 > Wuben T70, which are some of my most powerful flashlights. You can see the “obvious” differences Big Smile

This is the video review, much of the information was pointed out above. You can still watch it and let me know what you think of it, of course Wink

If you want, subscribe to the channel and leave your comments there, too! Thanks in advance Beer

Nice review! Crown

I like your outdoor photos. That last photo with 18 XHP70 lets every flashaholic’s heart beat faster. Love

You really look in detail at the positive and less positive aspects. I would say for this flashlight an integrated battery is better because it needs the 21700 cells with the best performance. For all other flashlights I always prefer removable batteries just like you.

I think this flashlight really needs Anduril. Wink The moonlight mode for taking photos of the leds, the muggle mode for novices, a well-programmed thermal regulation at all levels and definitely the lightning mode. Crazy

Amazing comprehensive review, MascaratumB! Especially with multiple videos to accompany the static review page. Intriguing how Imalent generously sent a MS18 for you to review, while this model has already been out for 2 solid years. That’s quite a testament to their confidence in your review quality. And really, you did not disappoint. Kudos! Thumbs Up

I’m amazed that Imalent hasn’t made a slipstream version upgrade of the MS18 UI, given the price at over 400€. Frankly, given the dangerous power of this light, one would expect that a forced low control (press+hold from off) would be a given. The fact that you will get the last brightness used and it could easily be right below turbo is… not good.

Preferably, I would think that a single click from OFF should never go above the medium setting. It’s just so easy to step up from there. And there’s also turbo had by double-click from OFF.

Also, given the massive size, this flashlight should have a tripod mounting point on the body or bottom collar of the head. At least there’s a shoulder strap!

Thanks for your words Skylight Wink

Ahah, that last photo is like a blooming flower Wink That’s what it seems to me, anyway!
The outdoor photos lost some quality whne making the gif, but I guess they portray (at some extent) the awesomeness of this flashlight in use and how distant it is from other already powerful lights (4000lumens is not weak, right?).

I tried to go through the many aspects that can make this flashligh work well and “fail”. The runtimes and thermal control is something I can check with more time of use.
Regarding the battery pack, I completely agree with you! However, to explain my thoughts well, I said what I said because, if within some years Imalent cannot repair a damaged pack or produce new ones, users may have an expensive flashlight laying there without many repair options. I do recognize, though, that in this case it is better and – eventually – safer to have such pack instead of “user-replaceable” cells.

As for an Anduril, well, it would be FUN AS FOLK!!!! Party
I couldn’t get any “above LED” beamshot due to the 700lumens and that huge head! It would be funny to ramp it up and down. And specially having that “start from lowest” option, above all!

Thanks again Wink

Well, I also felt surprised with the proposal from Imalent, but after considering and checking the legitimacy of the member, I decided I could accept it. But it was not an immediate “yes!”

Also, I warned that I would portray the goods and not so good aspects, showing the flashlight in action but not goldening the pill! I hope I did it in the best way for users or potential buyers to see Thumbs Up

Indeed, as I pointed out too, the UI could get some improvements, even if this is a “Lumen War” flashlight! Some safety on the “first click” would be appropriated . Otherwise, we’ll need to look away when turning it on to avoid bad surprises Big Smile Or…just use it outdoor! ONLY Silly

But I guess some things in this flashlight are a self commitment to use it with responsibility and saftey, to overcome some of the “fails” it mays have. Definitely not a flashlight for non enthusiasts, maybe. Only if they’re rich and adventurous Silly

Oh, and yes, tripod mount and High CRI in this light would be “unpayable” Wink

Once again, thank you Wink

To complement on the thermal control discussion that I mentioned above, I posted the following comment on ChibiM’s thread:
https://budgetlightforum.com/comment/1811377#comment-1811377

MascaratumB wrote:
So, I picked my MS18 today to check how it behaved in comparison with ChibiM’s one.
Honestly, I didn’t do a test that long , but I guess the conclusions can be retrieved from the table below.

Test was made at 10.000 lumens during 10 minutes only.

I stopped the test, as the head of the flashlight was already too hot to handle (if grabbed by the head), although handling it through the battery tube with thumb on the switch was still OK, but warm. By then the tube was at around 38.3ºC

At 10m I also felt some different smell, and while appraching the head to smell it, I accidentally touched the host with the nose tip and burned it Ughh Not nice! Blame is on me Thumbs Up

I stopped the test because, given the heat progression, I knew this would lead to similar results to what ChibiM got.

Voltage ºC near the switch ºC head (near bezel)
start (OFF) 16.38V 22.4ºC 22ºC
1 minute 15.74V 25.3ºC 26.9ºC
5 minutes 15.62V 34.4ºC 45.3ºC
10 minutes 15.56V 42.8ºC 65.5ºC

If at 10 minutes the exterior is at this temperature, I will assume that the inside is above 70ºC , which means that the fan didn’t activate , as stated in the User Manual. Of course, without having a way to measure it internally, this is just a wild guess, but it seems logic to me that the heat will be higher in the internals.

This said, what I can say, again, is DO NOT LEAVE THIS FLASHLIGHT ON UNATTENDED, in any level, but specially at this one. If above it, the fan will turn ON. If below, I believe that the light will still get hot, but the amount of heat is probably lower.

Also, this test is of course much more “accurate” than the one I did yesterday in which the battery was more drained, while today it was starting freshly charged !!

Thanks ChibiM for alerting to this situation! Thumbs Up

Thanks for this review! It’s pretty cool that Imalent was willing to send this to you, you covered everything very well and your beamshots are great! All your pictures are high-quality and your formatting makes it easy to see the important information.

For all the wow factor that this has it just seems too bulky and ridiculous to actually be all that useful…. and to hear that it can’t run on 10K lumens without eventually overheating is very disappointing.

Thanks for your words, LuxWax! Wink

Honestly, coming from you, that make the video reviews with so much quality, I feel flattered, but it is some grades below to you and other folks do in video and photo quality! As I said, My phone only allows this Big Smile

Well, not saying that this flashlight deserves more than a cheapper one, in terms of writing and showing what it does, it has, in fact, more aspects that can and need to be focused. So I tried to do the best I could with the “tools” and knowlegde I have.
I hope it portrays it Blushing

I wouldn’t say that it is not usefull, because it is! We only need to carry it to the places where it is needed (S&R situations, as example), or in case you have a wide extension of territory to check.
It is not easy to carry it, but it is feasible with the shoulder strap.

As for the 10K level, well it is really unfortunate that it gets that hot without decrease or fan to cool it down. In good truth, I guess the intermediate levels are the ones that I used less when carrying it. I felt more “secure” when the fan turned ON, even without knowing this situation.Then I jumped to Turbo Big Smile Evil

Thanks again and keep up the good work on the reviews too Wink

Haha glad you like the videos Smile Really though, your photography is very good, and you are doing a lot with your phone camera – the beamshots are great and the product photos are detailed. Also the last picture was really cool!
I might suggest trying to find some brighter lights for the detailed product shots, since the MS18 is black some of the details are a bit harder to see. The outdoor shots you took help display some of those details a bit better since it’s brighter outside. In fact, it might be helpful to try a different background other than white, since the high contrast can be difficult for the phone camera to handle. It still looks good though!

I’ve never done SAR so maybe it is good for that, but yeah it’s probably amazing for checking large areas of land at night. I guess it seems more like a “keep in the truck and use for a couple minutes as needed” kind of light, rather than something good for any extended carry. For most applications, I feel like it’s not worth lugging around something so massive when smaller lights provide plenty of lumens without the heft. Everybody has their own needs though! Whatever scenario this light is needed for must be pretty serious LOL

Hopefully this is something that Imalent sees and will work on fixing, that is a major hang-up I think for such an expensive light. It likely won’t be an issue to most users anyways, it’s probably hard to stick to 10K when you can have 60K Cool
