FourSevens Maelstrom Regen MMR-X


MMR-X 2 The FourSevens MMR-X is another light in the family of quality products available from FourSevens. This platform is one of their larger offerings (though still pretty small for its level of light output) and is unique in the fact that it is rechargeable through a micro-USB cable. This would be an excellent duty-gear, truck, or nightstand light for nearly any consumer.

The MMR-X offers the ability to program the light from a series of 5 different options, including varying combinations of moonlight, low, high, max, strobe, beacon, and SOS. I found configuration 2 to fit my everyday needs best, allowing me to cycle between max and low depending on what I needed it for.

The MMR-X is powered by a proprietary 18650 lithium ion rechargeable battery; a non-FourSevens 18650 battery can be used, however certain features of the light are lost. At a replacement cost of $15 from FourSevens, there should be no need to use any other branded battery. For a multiuse rechargeable battery, I applaud FourSevens for not charging a ridiculous amount of money for a replacement. On max output the battery is listed to last 2 hours, although in testing I found it to last closer to 2.5 hours before seeing a significant reduction in brightness. From a full discharge, it took between 4-5 hours to recharge the flashlight to full capacity. A sealed micro-USB input is contained where the head meets the body and a small red or green light informs you of where your battery is at in the recharging process.

The light itself has a very nice fit and finish and has a nice aggressively scalloped bezel that can be used as an improvised striking tool if things got nasty; it would definitely leave a mark. For those who don’t want such an aggressive bezel, you are in luck because it also comes with a smooth bezel which easily screws on. In “burst” mode, the MMR-X powers out 800 lumens of light which is reduced to 400 lumens after 1 minute of continuous run time. In FourSevens fashion, the light comes with a few spare o-rings, a lanyard, and an alternate tail cap clicky and boot so the user can choose from a long click or a short click. Their 10 year no-hassle warranty also allows owners to rest assured they won’t need to spend any more of their hard-earned money on a replacement should anything go wrong.

The MMR-X is advertised to survive a 1 meter (3.2ft) drop which I feel is a little low. Under testing, the light survived a 3 meter (10ft.) fall on concrete. The light also survived an even larger fall at 6 meters (20ft.), but the battery did not. I can’t fault the battery for breaking at 20ft. because it is only advertised to 3ft., but I’d like to see more impact resistance in the future. It is certainly rugged enough for everyday use but having an extra 18650 battery around wouldn’t be a bad idea. The light performed well in water submersion tests, meaning that puddle and shallow lake drops won’t hurt this beast. It also operated properly after being subjected to freezing temperatures for 24 hours.MMR-X 1

Overall this is an excellent light with various uses and the convenience of being rechargeable via any USB port. Replacement batteries, although proprietary (to use all functions of the light), are reasonably priced as well. In the future I’d like to see some ultra-impact survival lights from FourSevens, focused on the market of users who need a light to work no matter what they do to it. If FourSevens offered a fully potted model with some of their best features from their most popular flashlights, they would posture themselves to crush their competitors with functionality, reliability, and toughness.

FourSevens Atom AL


Atom AL 2

The FourSevens Atom AL is an ultra-compact every day carry (EDC) LED light with useful features and great value.  FourSevens is known for their ingenuity and quality products and the Atom AL is no different.  This light fits in the palm of your hand and is great for pocket, truck, or desk carry.

The Atom AL is advertised to run on CR123A batteries with 110 max lumens and 6 low lumens.  On low setting it can run for 40 hours and also runs for 3.5 hours on max.  It is also submersible down to 3 meters and can withstand an impact resistance of 1 meter for you clumsy types.  During a submersion test, the Atom AL continued to run with no issues when placed in a vat of water to simulate puddle or shallow lake water drops.  The light continued to run during the entire 30 minutes it was submersed for, and even heated the water for those of you who like to sip on warm water.  The light passed the 1 meter concrete drop test with no issues, and as a test of its limits it continued to work after a 6 meter (20ft) concrete drop test as well.  Its compact size and stout construction makes it like a bulldog of ultra-compact lights.  The manufacturer specifications don’t mention anything about operating temperatures, but 24 hours in a freezer didn’t stop this bulldog from shining like it would in normal temperatures.

The light is considered a “mule” meaning it has no mirrored reflector, resulting in a flood-like shallow and wide throw of light.  The area around the LED normally reserved for a reflector is coated with a glow in the dark substance, which is a unique feature allowing for quick locating if dropped or lost in the dark shortly after a recent use.  The beam has no “hot spot” and is useful in short and medium range distances.  The light has a low setting (6 lumens) and a high setting (110 lumens) accessible by twisting the light in one of two stages.  This simple user interface makes it easy to access either setting; this is a welcome change to some of FourSevens’ other more complex and sometimes confusing user interfaces.

The exterior is slightly “grippy” which allows for sweaty or cold hands to firmly grasp the light when twisting it on.  As a side note, out of the box the light was a little hard to twist with one-handed Atom AL 3operation.  After cleaning the threads between the upper and lower portions of the light, it became much easier to operate.  The base of the light also contains a magnet allowing it to be affixed to any ferrous surface.  This magnet really comes into play during pocket carry because your car keys will stick to it, so just make sure you carry them in opposite pockets to avoid the hassle.  The magnet becomes the biggest benefit when the light is used in conjunction with the optional 360 degree headlamp kit available from FourSevens for only $15.  I tested this feature out as well and it makes for an excellent combination.  While wearing the headlamp and light combo kit might qualify you for the household geek of the year award, the convenience of the units together make the headlamp kit a must-have option.

The light comes from the factory with spare O-rings and a handy lanyard, which I think are nice touches.  Some people don’t like lights requiring more expensive CR123A batteries; these people are in luck because FourSevens also makes versions of this same light which handle AA, AAA, and CR2 batteries.

FourSevens Preon 2 Review

Preon 2 Main

The FourSevens Preon 2 is a great everyday carry light. Powered by 2 AAA batteries, it is very slim and easy to carry in the pocket. It is about the size of a standard size Sharpie marker.

Preon 2 with Sharpie

The advertised output is 160 Lumens. It has a very shallow reflector, so it does not project the beam very far, but the light is still usable for seeing movement out to about 50+ yards. The light has 3 output levels and 4 Special modes. The modes are Low(2.2 lumens), Medium(22 lumens), High (160 lumens), Strobe, SOS, Beacon Hi and Beacon Lo. The light turns on in low mode and to access other modes, you can either “soft” tap the tailcap switch, or turn it off and back on within a second. Once you cycle through Low-Med-High twice in quick succession, you will start to cycle through the special modes. The light has a beautiful anodizing that feels almost like velvet to the touch. It holds up very well, except around the hard edges, like the bezel. The tailcap activation switch is very positive and easy to actuate, but it’s almost TOO easy. If you carry this light in your pocket, rather than clipped inside of your pocket, you are sure to activate. One way around this is to purchase a flat tailcap from FourSevens. It is the tailcap that comes standard on their single battery version. With the flat tailcap installed, you must twist the bezel to activate the light. Another way is just to unscrew the bezel. It will work just like having the flat tailcap, except you will have to make sure the clicky switch is on at the same time. The lights are a little pricey, for their size, but very much worth it, in my opinion.
