Review - FOURSEVENS Maelstrom MMU-HD

The Maelstrom MMU-HD is one powerhouse of a flashlight.
Upon thinking about what I should write my next blog post about, I realized that I had never actually reviewed the FOURSEVENS Maelstrom MMU-HD (aka Maelstrom S18). This bright powerhouse of a flashlight isn't something that you'd be carrying every day. However, it would be a great light to keep around to show off to friends, or in case you ever had to light something up that was really far away.

The MMU-HD has a smooth reflector for throwing light far.
Using 6 CR123 batteries, the MMU-HD outputs a whopping 1200 lumens on high, 400 lumens on medium and 80 lumens on low. It has three brightness modes (Low, Medium, High) and two special modes (Strobe, SOS). The beam on the MMU-HD is narrow, which means that it's designed for throwing the light far. From my experience, the brightness of the MMU-HD is comparable to that of a car headlight.

The mode selection for the MMU-HD is very unique when it comes to FOURSEVENS flashlights. The modes are selected by rotating a tactile ring near the tailcap. The ring makes an audible "click" when you select a new mode. It's very easy to remember which mode is which, to allow for easy mode manipulation, even in the dark.

The case on the MMU-HD is very attractive;
fitting for such a nice flashlight.
Well, enough about the modes... how big and heavy is this thing? Yeah, I know, everything comes with a cost. The exchange for having such an insanely bright flashlight is that it weights about 28 oz with batteries. That's 1 3/4 lbs! It's also 9.2" long and 2.5" wide at the head (1.8" wide flashlight body). It's quite a hefty light. If you're a security guard or police officer, it may be a light that you would like to carry, because in a pinch, you can use it as an impact weapon, similar to those D Cell Maglites that you often see officers carry.

If you wanted to carry the MMU-HD, it does come with a carry pouch/holster. It also comes in a very stylish aluminum case, which is great for transport.

Needless to say, I'm pretty impressed by the Maelstrom MMU-HD. In my opinion, it's a homerun if you can afford the $215 price tag. It may be just the flashlight that you are looking for.


  1. Great Job! I appreciate your writing. Thanks for your detail info. Here I would like to suggest a safety tool.
    Raporlite -The World’s Brightest Tactical Flashlight
    A tactical flashlight could be your most effective weapon when it comes to self-defense. If you’re under attack, you don’t want to hesitate for a second and by using the world’s brightest tactical light you ensure you can identify the assailant immediately and take appropriate action.
    Raporlite is no ordinary flashlight. Our tactical flashlights are used by law enforcement officers and military personnel who need to use the brightest lights available on their weapons. A gun with a mounted Raporlite allows the user to see their target clearly, even in the darkest conditions, and aim with complete accuracy.
    Using a handgun in low light can be a recipe for disaster. Not only are you likely to miss your intended target, but you are also at risk of injuring anyone who may wander in front of your path if you cannot see clearly. The best tactical flashlights light up the area like daylight so you can see exactly what your gun is pointing at.
    A tactical flashlight – your first line of defense
    But Raporlite tactical flashlights don’t have to be mounted to a gun in order to be a great tool for self-defense. Attackers generally don’t like to be seen and just shining this super bright light at them may be enough to deter opportunistic attacks.
    If you’re planning to be out in an area that is not well lit, it makes sense to carry one of our compact LED flashlights with you. We’ve all been in situations where we feel unsafe walking in the street at night and for good reason – most attacks happen under cover of darkness. You have less chance of being mugged if there are no shadowy areas for attackers to lurk in and as the world’s brightest tactical flashlight Raporlite can illuminate half a mile in front of you.
    Another simple but effective function of the Raporlite tactical light is its ability to dazzle would-be attackers. As your first line of defense, shining this insanely bright light into the assailant’s eyes will disorient them and cause them to lose their vision for a few seconds, allowing you to escape or raise the alarm.
    If it comes to it, you can also use our tactical flashlights as a weapon if you are attacked and have no other method of self-defense. The aggressive attack bezel can be used to strike an attacker in the face before he can make advances.
    What is the best tactical flashlight?
    Our flashlights are compact, making them easy to carry on your person. They’re also rechargeable so there is no risk of running out of batteries, rendering your flashlight useless. As the world’s brightest tactical flashlight, the Raporlite is three times brighter than the nearest competitor and also the best value, at a price you’ll find hard to believe.
    When it comes to your safety, there is really no excuse to settle for anything less than the best. By choosing a Raporlite tactical LED flashlight, you can have peace of mind knowing that you are fully prepared in case of attack.

  2. Thanks for this review. I just purchased an MMU-HD after reading your comments and have used it on several night walks. The tail switch was defective when it arrived (it turned the light on but will not turn the light off so I'm turning the light on by tightening the tail cap and turning it off by unscrewing it) while waiting for the replacement part from FourSevens. Other than the defective switch (FourSevens offered to send a replacement without any hassle), the build and finish of the light is excellent.

    I live in a rural area in Colorado that has Cougars (the four legged kind), Bears, Deer, Elk, Fox, etc. I like to make a sweep of my immediate area with my flashlight to see if there are any glowing eyes looking back at me and, if so, identify what the critter is (and make a threat determination) at up to about 150 yards. Considering how non-reflective a nocturnal critter's hide is, this is a serious challenge for a flashlight. The MMU-HD on High Power takes care of the job. It's low setting of 80 Lumen is a bit brighter than I prefer for general night time navigation, but it is acceptable. The 1200 Lumen setting reaches out a long way with authority.

    One of this light's features is current regulation that allows the use of RCR -123 batteries, the rechargeable version of the CR-123. The MMU-HD houses 3 stacks of 2 batteries so it's using 6 batteries at a time. Being able to use rechargeable batteries is a convenience and an economy.

  3. Tactical flashlight is most important for our GUN or PISTOL. your writing concept is able to make it more clear and I hope most of the people able to earn some knowledge about the tactical tech devices

  4. The list of qualities for an excellent waterproof lighter is quite long for me. I've been researching and trying to find ones that are reliable, durable, safe to use, refillable and easy to use. For me, nothing beats the UST Stormproof Floating Lighter. It's durable and affordable at the same time. My dad used to say that I must invest in topnotch brands. I know that he meant well and that's why I really followed his advice on choosing the best waterproof lighters in town. For more, see this awesome link:
