Tactical series of higher output lights.
 
'''MMS''' - 2xCR123A or 1x18650 4-mode thrower with Cree XP-G and output levels of 0.2, 28, 200, and 350 lumens introduced in May 2012. Two different mode groups available: H-M-L-Moonlight or Turbo-Strobe-SOS-Beacon. Modes are selected by turning the head to 4 different positions. This light was formerly the 4Sevens G5.


'''MMS''' - 2xCR123A or 1x18650 4-mode thrower with Cree XP-G and output levels of 0.2, 28, 200, and 350 lumens introduced in May 2012. Two different mode groups available: H-M-L-Moonlight or Turbo-Strobe-SOS-Beacon. Modes are selected by turning the head to 4 different positions.
'''MMU''' - 1x26650 2-mode light with [[Luminus]] SST-90 LED and maximum output of 800 (Low is 120 lumens). The light memorizes the last mode used. Similar to [[SureFire]] lights, the tail clicky is for momentary On only when the tailcap is loosened a half turn. To keep the light on, the tailcap must be fully tightened. Foursevens sells a special 26650 battery for this light that has higher current capacity. Introduced in May 2012. This light was formerly the 4Sevens S12.


'''MM-X''' - 2xCR123A or 1x18650 4-mode thrower with Cree XM-L and a maximum output of 480 lumens introduced in May 2012. Two different mode groups available: H-M-L-Moonlight or Turbo-Strobe-SOS-Beacon. Output levels are 0.3, 30, 270, and 480 lumens. Modes are selected by turning to 4 different positions. This light is available cool white or neutral LED tints. The neutral has slightly less output. This light was formerly the 4Sevens X7
'''MMU-HD''' - 6xCR123A 5-mode light with a Luminus SST-90 LED and maximum output of 1200 lumens (Low is 80 lumens). Modes are selected by rotating the tail of the light. This light does not accept 17670 or 18650 batteries but can handle 16340's. Each set of 2 batteries in the holder is in parallel, so the operating voltage is 4.5-8.4V. Introduced in May 2012. This light was formerly the 4Sevens S18.


'''MMU-X''' - 1x26650 2-mode light with Cree XM-L and output levels of 100 and 640 lumens. This light features a lock-out tailcap, mode memory, and thermal regulation. The MMU-X uses a lower current type of 26650 battery than the one for the MMU. So you can use the MMU's battery in the MMU-X, but shouldn't use the MMU-X's battery in the MMU. Introduced in May 2012. This light was formerly the 4Sevens X12.

'''S12''' - 1x26650 2-mode light with [[Luminus]] SST-90 LED and maximum output of 800 (Low is 120 lumens). The light memorizes the last mode used. Similar to [[SureFire]] lights, the tail clicky is for momentary On only when the tailcap is loosened a half turn. To keep the light on, the tailcap must be fully tightened. The 26650 is a special size lithium-ion battery. 4Sevens sells the battery and charger separately. At 3900mAh capacity, it has more capacity than a typical 2400mAh 18650 and is driven at up to 5 amps. First available in February 2011. There was also a limited edition copper version with a copper head for better heat sinking and gold plating to prevent tarnishing.

'''Preon P0''' - 1xAAA 2-mode stainless steel twisty with a Cree XP-E LED. Output is 0.24 or 25 lumens. Modes are selected by turning the light off and back on again quickly. The light comes on in Low. Introduced in May 2012.
 
'''Preon P1''' - 1xAAA 7-mode twisty with Cree XP-G LED. Has a pocket clip and matte finish (no knurling) and is available in black, blue, red, yellow, and satin titanium. Regular operation cycles through 2, 13, and 70 [[ANSI-NEMA FL-1|ANSI]] lumens (40m throw), but if you cycle quickly through all the modes twice, you also get strobe, SOS, and high and low beacon modes. Parts are interchangeable with Preon 2, which allows use of a clicky tail. Introduced in May 2012. This light was formerly the 4Sevens Preon 1.
 
'''Preon P2''' - 2xAAA 7-mode clicky with Cree XP-G LED. Has a pocket clip and matte finish (no knurling) and is available in black, blue, red, yellow, satin titanium, and titanium black (with titanium head and tail but black body). Regular operation cycles through 3, 26, and 120 ANSI lumens (59m throw), but if you cycle quickly through all the modes twice, you also get strobe, SOS, and high and low beacon modes. Parts are interchangeable with Preon 1, which allows use of a flat tail and using the light as a twisty. A warm white high CRI version is available in black or titanium black which has less output. Introduced in May 2012.


'''S18''' - 6xCR123A 5-mode light with a Luminus SST-90 LED and maximum output of 1200 lumens (Low is 80 lumens). Has the same switch as other Maelstroms and modes are selected by rotating the tail of the light. This light does not accept 17670 or 18650 batteries but can handle 16340's. Each set of 2 batteries in the holder is in parallel, so the operating voltage is 4.5-8.4V. Introduced in August 2011. Review: [http://www.candlepowerforums.com/vb/showthread.php?319505 Selfbuilt]
'''Preon PenLight''' - 2xAAA 3-mode reverse clicky light with Cree XP-G2 LED. Modes are 5, 50, and 180 lumens. Has mode memory. Designed to look more like a real pen than the other Preons and is available in black, orange, mocha, and blue. Introduced in April 2013.


=== Quark Pro ===


Quark Pro flashlights lights have a reverse clicky on the tail and feature 8 modes. With the head tightened, the modes are Max and Strobe. With the head loosened the modes are Moonlight, Low, Medium, High, SOS, and Beacon. They feature a Cree XP-G LED in cool white (currently XP-G2), but some models are also available with a warm white high CRI LED that offers better color rendering at the expense of about 30% of the output. Some have neutral versions which typically have about 7% less output. For the most part, the heads are interchangeable except the QP2L which has an operating voltage of 3-9V while the rest of the series has a voltage range of 0.9-4.2V. The Quark Pro series can tailstand.


'''Quark QP2A''' - 2xAA light with output of 0.2, 4, 22, 85, or 206 OTF lumens in addition to flashing modes. This light was formerly the 4Sevens Quark AA² Regular.


'''Quark QP2A-X''' The Quark QP2A with Cree XM-L LED (currently XM-L2) provides 0.3, 2.7, 24, 115, or 280 lumens.


=== Preon ===
'''Quark QP2L''' - 2xCR123A light with output of 0.2, 4, 22, 85, and 230 OTF lumens. In addition to the standard cool white tint LED, this light is also available with a high CRI or neutral tint LED. This body will not accept 18650 cells. The head of the 123² lights can accept up to 9V. They will also run fine on a single lithium-ion battery (17670) but will not be regulated the entire time. This light was formerly the 4Sevens Quark 123² Regular.


'''Preon 1''' - 1xAAA 7-mode twisty with Cree XP-G S2 LED introduced in November 2010. Has a pocket clip and matte finish (no knurling) and is available in black, blue, red, yellow, and titanium. Regular operation cycles through 2, 13, and 70 [[ANSI-NEMA FL-1|ANSI]] lumens (40m throw), but if you cycle quickly through all the modes twice, you also get strobe, SOS, and high and low beacon modes. Parts are interchangeable with Preon 2, which allows use of a clicky tail. Original version introduced in November 2009 with 1.8, 8.5, and 70 OTF lumens. A high CRI version in black was released in November 2011.  
'''Quark QP2L-X''' The Quark QP2L with a Cree XM-L LED (currently XM-L2) has output of 0.3, 3, 65, 160, and 360 lumens. It is also available with a neutral tint LED.


'''Preon 2''' - 2xAAA 7-mode clicky with XP-G S2 LED introduced in November 2010. Has a pocket clip and matte finish (no knurling) and is available in black, blue, red, yellow, titanium and titanium black (with titanium head and tail but black body). Regular operation cycles through 3, 26, and 120 ANSI lumens (59m throw), but if you cycle quickly through all the modes twice, you also get strobe, SOS, and high and low beacon modes. Parts are interchangeable with Preon 1, which allows use of a flat tail and using the light as a twisty. Original version, introduced in November 2009, used a XP-G R5 and had modes of 2.2, 22, and 160 OTF lumens. In May 2010, a limited edition with warm white XP-G Q5 LED was introduced. In June 2010, a limited edition with neutral white XP-G R4 was introduced. In October 2011, there was another run of neutral XP-G Preon 2's. A high CRI version in black was released in November 2011.  
'''Quark QPA''' - 1xAA light with output of 0.2, 4, 22, 85, and 109 OTF lumens. This light was formerly the 4Sevens Quark AA Regular.


=== Quark ===
'''Quark QPL''' 1xCR123A light with output of 0.2, 4, 22, 85, and 205 OTF lumens. The '''QPLC''' seems to be the same light only without a clip (the clip can be removed with the other lights of the series). The QPLC is available in a high CRI version. This light was formerly the 4Sevens Quark 123 Regular.


[[File:Quark-123-2.jpg|thumb|300px|Quark 123² Tactical]]Quark lights were introduced in May 2009 with '''Cree XP-E R2''' LED's. Models are available in Regular or Tactical version. The power switch on the Tactical version is a forward clicky that protrudes from the back of the light and prevents tailstanding. The Regular version has a reverse clicky that does not protrude and can tailstand. The Regular version has max and strobe available with the bezel tightened while with a loosened bezel you use the reverse clicky to cycle through moonlight, low, medium, high, SOS, and beacon modes. The Tactical version has only two modes (tightened or loosened), but can have any of the 8 modes programmed in. The tactical models suffer from [[Terminology#preflash|preflash]] where sometimes if the light is set to come on in low it will flash very bright when turned on. All of the Quarks have a mild preflash in Moonlight mode where the light flashes to Low before going to Moonlight. Parts are generally interchangeable but only the head of the 123² and 123² Turbo can handle the higher voltage of 2 CR123A or 2 lithium-ion batteries. All Quarks have orange peel reflectors. The clip is reversible in the sense that the body tube is reversible (the head and tail threads are identical), therefore the light can be assembled for a bezel-up clip or bezel-down. All of the main Quarks were updated to '''Cree XP-G R5''' emitters in December 2009. In September 2011 '''Quark X''' versions of the AA² and 123² were introduced in both regular and tactical versions. For thermal protection on maximum brightness, the Quark X lights drop output to about 70% after 3 minutes.
===Quark Tactical===


'''Limited Editions''' In November 2011, the regular interface versions of the Quark 123 and 123² were available with '''high [[Terminology#CRI|CRI]]''' Cree XP-G LED's (CRI value 85+). These lights have a warm white tint and less output (4Sevens did not release output measurements, but Cree literature indicates the highest bin of 85 CRI XP-G's is Q3) than the standard XP-G R5. In October 2011, neutral versions of the four Quark X lights as well as neutral XP-G versions of the 123² and AA² regular and tactical Quarks were introduced. [[File:Ledtints.jpg|thumb|300px|Side-by-side comparison of a number of 4Sevens and other flashlights showing tint differences. Click for full caption.]]The entire line was available with '''Cree XP-G S2''' emitters in November 2010. In May 2010, '''warm white''' (tint 7A3 or 7B4) XP-G Q5 LED's were shipped after a pre-order period (Preon2, 123² Tactical, AA² Tactical, MiNi 123, MiNi AA, MiNi CR2, 123² Turbo, and AA² Turbo). In June 2010, '''neutral white''' (tint 4C0 or 4D0) XP-G R4 versions were introduced (Preon2, 123² Regular and Tactical, AA² Regular and Tactical, MiNi 123, MiNi AA, and MiNi CR2). Both of the 2010 limited editions featured "green packaging" (a ziplock bag) instead of coming in a box and were reduced in price by $2. When the standard LED was the XP-E R2, a limited edition '''neutral white''' (tint 5A) XP-E Q3 was available. A limited edition '''titanium version''' of all of the main lights came out in September 2009 featuring a Cree XP-G R4 emitter (the first 1000 were numbered).  
The Quark Tactical series is very similar to the Quark Pro series, but features a forward clicky and a different user interface. The tactical version has only two modes (tightened or loosened), but can have any of the 8 modes of the Pro programmed into those. The tactical models suffer from preflash where sometimes if the light is set to come on in low it will flash very bright when turned on. All of the Quarks have a mild preflash in Moonlight mode where the light flashes to Low before going to Moonlight.

=== Quark MiNi ===
'''QB2L''' 2xCR123A light with a Cree XP-G LED. The output levels are 0.2, 4, 22, 85, or 230 OTF lumens in addition to flashing modes. This light was formerly the 4Sevens Quark 123&sup2; Turbo.


The MiNi was first introduced in November 2009 with Cree XP-G R5 LED's and was updated to the XP-G S2 in November 2010. These lights are more compact due to the absence of a clicky switch. All are twisty. By default they are 3-mode lights, but if you cycle through the modes twice by twisting the head on and off quickly, it becomes a 7-mode light with the addition of strobe, SOS, and high and low beacon modes.
'''QB2L-X''' 2xCR123A  light is similar to the QB2L but with an even a larger head (39mm vs. 30mm) and a Cree XM-L LED. Has same tactical interface, but uses a new driver that does not exhibit preflash. Output is 0.3, 8, 60, 260, or 450 lumens along with Strobe, SOS, and Beacon. This light is also available with a neutral tint XM-L that will have about 7% less output.


'''MiNi 123''' - 1xCR123A XP-G R5 twisty with output levels of  3, 40, and 189 [[Terminology#OTF|OTF]]. A limited edition neutral white version with a Q3 5A emitter was released in December 2009. A titanium version started shipping in January 2010 (cool or neutral). A limited edition XP-G S2 version, introduced in November 2010, had output levels of lumens 8, 43, and 135 [[ANSI-NEMA FL-1|ANSI]] lumens. In December 2010, a very limited edition (100 units) titanium version with XP-G S3 was introduced (there was no S2 version in titanium) which should have output of 144 ANSI lumens (though it was not tested). Also in December 2010, S3's were put in limited edition satin finish (bead blasted) titanium 123's (also Quark Turbo 123&sup2;'s). A version with a Cree XM-L LED (called a '''MiNi X 123''') with 210 OTF lumens of output was announced in December 2010 (their first light to use this LED). In February 2011, a satin finish titanium version with XP-G S2 was introduced. In October 2011 neutral versions of the MiNi 123 and Mini X 123 were introduced. A high CRI version of the MiNi 123 was released in November 2011.

=== Quark Mini ===


'''MiNi AA''' - 1xAA XP-G S2 version has output levels of 4, 21, and 66 ANSI lumens (51m throw). The original XP-G R5 version had output levels of 2.7, 25, and 90 OTF lumens. A limited edition neutral white version with a Q3 5A emitter was released in December 2009. A titanium version started shipping in January 2010 (cool or neutral). A limited edition XP-G S2 edition was introduced in November 2010 with maximum output of 70 ANSI lumens and 51m throw. A high CRI version was released in November 2011.

An Atlanta-based flashlight manufacturer. Originally an online store selling other brands, they made their own lights under the 4Sevens label before separating the store and the brand.

Foursevens has a very good reputation as a builder of lights (their lights are actually manufactured in China with close ties to Olight) in the CPF forums. They often announce new products in the CPF Marketplace before they are listed on their website and post special discount codes for sales in addition to CPF member discount codes.

Flashlights

Many of the older lights and variations were branded under the original 4Sevens label and are still available on that page. This page starts with the lights with the Foursevens branding.

Limited Editions: In August 2012, all of the lights with Cree XP-G LEDs were made available with Cree XP-G2 LEDs, promising 20% more output, but no actual lumen figures were provided. The LEDs all came from the same cool white bin.

Maelstrom

Tactical series of higher output lights.

MMS - 2xCR123A or 1x18650 4-mode thrower with Cree XP-G and output levels of 0.2, 28, 200, and 350 lumens introduced in May 2012. Two different mode groups available: H-M-L-Moonlight or Turbo-Strobe-SOS-Beacon. Modes are selected by turning the head to 4 different positions. This light was formerly the 4Sevens G5.

MMU - 1x26650 2-mode light with Luminus SST-90 LED and maximum output of 800 (Low is 120 lumens). The light memorizes the last mode used. Similar to SureFire lights, the tail clicky is for momentary On only when the tailcap is loosened a half turn. To keep the light on, the tailcap must be fully tightened. Foursevens sells a special 26650 battery for this light that has higher current capacity. Introduced in May 2012. This light was formerly the 4Sevens S12.

MMU-HD - 6xCR123A 5-mode light with a Luminus SST-90 LED and maximum output of 1200 lumens (Low is 80 lumens). Modes are selected by rotating the tail of the light. This light does not accept 17670 or 18650 batteries but can handle 16340's. Each set of 2 batteries in the holder is in parallel, so the operating voltage is 4.5-8.4V. Introduced in May 2012. This light was formerly the 4Sevens S18.

MMU-X - 1x26650 2-mode light with Cree XM-L and output levels of 100 and 640 lumens. This light features a lock-out tailcap, mode memory, and thermal regulation. The MMU-X uses a lower current type of 26650 battery than the one for the MMU. So you can use the MMU's battery in the MMU-X, but shouldn't use the MMU-X's battery in the MMU. Introduced in May 2012. This light was formerly the 4Sevens X12.

MM-X - 2xCR123A or 1x18650 4-mode thrower with Cree XM-L and a maximum output of 480 lumens introduced in May 2012. Two different mode groups available: H-M-L-Moonlight or Turbo-Strobe-SOS-Beacon. Output levels are 0.3, 30, 270, and 480 lumens. Modes are selected by turning to 4 different positions. This light is available cool white or neutral LED tints. The neutral has slightly less output. This light was formerly the 4Sevens X7.

Preon

Preon P0 - 1xAAA 2-mode stainless steel twisty with a Cree XP-E LED. Output is 0.24 or 25 lumens. Modes are selected by turning the light off and back on again quickly. The light comes on in Low. Introduced in May 2012.

Preon P1 - 1xAAA 7-mode twisty with Cree XP-G LED. Has a pocket clip and matte finish (no knurling) and is available in black, blue, red, yellow, and satin titanium. Regular operation cycles through 2, 13, and 70 ANSI lumens (40m throw), but if you cycle quickly through all the modes twice, you also get strobe, SOS, and high and low beacon modes. Parts are interchangeable with Preon 2, which allows use of a clicky tail. Introduced in May 2012. This light was formerly the 4Sevens Preon 1.

Preon P2 - 2xAAA 7-mode clicky with Cree XP-G LED. Has a pocket clip and matte finish (no knurling) and is available in black, blue, red, yellow, satin titanium, and titanium black (with titanium head and tail but black body). Regular operation cycles through 3, 26, and 120 ANSI lumens (59m throw), but if you cycle quickly through all the modes twice, you also get strobe, SOS, and high and low beacon modes. Parts are interchangeable with Preon 1, which allows use of a flat tail and using the light as a twisty. A warm white high CRI version is available in black or titanium black which has less output. Introduced in May 2012.

Preon PenLight - 2xAAA 3-mode reverse clicky light with Cree XP-G2 LED. Modes are 5, 50, and 180 lumens. Has mode memory. Designed to look more like a real pen than the other Preons and is available in black, orange, mocha, and blue. Introduced in April 2013.

Quark Pro

Quark Pro flashlights lights have a reverse clicky on the tail and feature 8 modes. With the head tightened, the modes are Max and Strobe. With the head loosened the modes are Moonlight, Low, Medium, High, SOS, and Beacon. They feature a Cree XP-G LED in cool white (currently XP-G2), but some models are also available with a warm white high CRI LED that offers better color rendering at the expense of about 30% of the output. Some have neutral versions which typically have about 7% less output. For the most part, the heads are interchangeable except the QP2L which has an operating voltage of 3-9V while the rest of the series has a voltage range of 0.9-4.2V. The Quark Pro series can tailstand.

Quark QP2A - 2xAA light with output of 0.2, 4, 22, 85, or 206 OTF lumens in addition to flashing modes. This light was formerly the 4Sevens Quark AA² Regular.

Quark QP2A-X The Quark QP2A with Cree XM-L LED (currently XM-L2) provides 0.3, 2.7, 24, 115, or 280 lumens.

Quark QP2L - 2xCR123A light with output of 0.2, 4, 22, 85, and 230 OTF lumens. In addition to the standard cool white tint LED, this light is also available with a high CRI or neutral tint LED. This body will not accept 18650 cells. The head of the 123² lights can accept up to 9V. They will also run fine on a single lithium-ion battery (17670) but will not be regulated the entire time. This light was formerly the 4Sevens Quark 123² Regular.

Quark QP2L-X The Quark QP2L with a Cree XM-L LED (currently XM-L2) has output of 0.3, 3, 65, 160, and 360 lumens. It is also available with a neutral tint LED.

Quark QPA - 1xAA light with output of 0.2, 4, 22, 85, and 109 OTF lumens. This light was formerly the 4Sevens Quark AA Regular.

Quark QPL 1xCR123A light with output of 0.2, 4, 22, 85, and 205 OTF lumens. The QPLC seems to be the same light only without a clip (the clip can be removed with the other lights of the series). The QPLC is available in a high CRI version. This light was formerly the 4Sevens Quark 123 Regular.

Quark Tactical

The Quark Tactical series is very similar to the Quark Pro series, but features a forward clicky and a different user interface. The tactical version has only two modes (tightened or loosened), but can have any of the 8 modes of the Pro programmed into those. The tactical models suffer from preflash where sometimes if the light is set to come on in low it will flash very bright when turned on. All of the Quarks have a mild preflash in Moonlight mode where the light flashes to Low before going to Moonlight.

Quark QT2A - 2xAA light with output of 0.2, 4, 22, 85, or 206 OTF lumens in addition to flashing modes. Also available with a neutral tint LED. This light was formerly the 4Sevens Quark AA² Tactical.

Quark Turbo

The Turbo series is similar to the Tactical series except that the lights have a larger diameter head for better throw. The user interface and forward clicky are the same as the Tactical series.

QB2A 2xAA light with a Cree XP-G LED. The output levels are 0.2, 4, 22, 85, and 230 OTF lumens in addition to flashing modes. This light was formerly the 4Sevens Quark AA² Turbo.

QB2L-X 2xCR123A light is similar to the QB2L but with an even a larger head (39mm vs. 30mm) and a Cree XM-L LED. Has same tactical interface, but uses a new driver that does not exhibit preflash. Output is 0.3, 8, 60, 260, or 450 lumens along with Strobe, SOS, and Beacon. This light is also available with a neutral tint XM-L that will have about 7% less output.

Quark Mini

The Quark Mini series lights are more compact due to the absence of a clicky switch. All are twisty. By default they are 3-mode lights, but if you cycle through the modes twice by twisting the head on and off quickly, it becomes a 7-mode light with the addition of strobe, SOS, and high and low beacon modes. With exception of the Mini ML-X, all have Cree XP-G LEDs (currently XP-G2).

Mini M2A - 2xAA light has output levels of 3, 36, and 180 OTF lumens. Unlike other MiNis, the AA2 includes a clip. This light was originally the 4Sevens MiNi AA².
