Foursevens

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.

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 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.

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, 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 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 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 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 is 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 MiNi

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.

MiNi 123 - 1xCR123A XP-G R5 twisty with output levels of 3, 40, and 189 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 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 123²'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. Review: Lumens Review, Light Reviews, Light Reviews (titanium)
