4Sevens

An Atlanta-based flashlight dealer that formerly had separate websites like www.fenix-store.com and www.eagletac-store.com before consolidating the websites under www.4sevens.com. They have since added their own line of flashlights listed below. 4Sevens has sister stores in Poland and Canada.

4 Sevens has a very good reputation as a dealer and as a builder of lights (their lights are actually manufactured in China) 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

Maelstrom

Tactical series of lights. Announced in January 2010, but will not come out for several months.

G5 - 2xCR123A or 1x18650 4-mode thrower with Cree XP-G R5 and a maximum output of 350 lumens. Two different mode groups available: H-M-L-Moonlight or Turbo-Strobe-SOS-Beacon. Modes are selected by turning the head. Introduced in July 2010. Review: Selfbuilt

S12 - The "S" is probably for a Luminus SST LED.

S18 - Another possible SST light.

Preon

Preon 1 - 1xAAA 7-mode twisty with Cree XP-G R5 LED. Regular operation cycles through 1.8, 8.5, and 70 lumens, 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 November 2009.

Preon 2 - 2xAAA 7-mode clicky with XP-G R5 LED. Regular operation cycles through 2.2, 22, and 160 lumens, 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. Introduced in November 2009.

Preon ReVO - 1xAAA 7-mode twisty with XP-E R2 LED. Regular operation cycles through 1.8, 20, and 82 lumens, but if you cycle quickly through all the modes twice, you also get strobe, SOS, and high and low beacon modes. Power is current regulated instead of PWM of the other Preons which should be more efficient. Available in black or stainless steel and has more traditional knurling instead of a smooth finish. Not to be used with a lithium-ion battery whereas the Preon 1 can be, but is not recommended. Introduced in August 2010. Review by Selfbuilt.

Quark

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 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.

Limited Editions 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. In October 2010, S2 editions were introduced across the entire product line for November delivery (including Maelstrom, Preon and Quark MiNi) with Cree XP-G S2 emitters which are about 7% brighter than R5 bin emitters.

Quark 123 - 1xCR123A light with 0.2, 3.5, 18, and 70, and 170 lumens in addition to flashing modes. The XP-G R5 output is 0.2, 4, 22, 85, and 206 lumens.

Quark 123² - 2xCR123A light with 0.2, 3.5, 18, 70, and 190 lumens in addition to flashing modes. The XP-G R5 output is 0.2, 4, 22, 85, and 230 lumens. This body will not accept 18650 cells, but a separate body tube is offered that will. 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.

Quark 123² Turbo - Similar to the 123² but has a larger, deeper head for more throw and a Cree XP-G R5 emitter. Offered only with a tactical user interface, the output levels are 0.2, 4, 22, 85, and 230 lumens in addition to flashing modes.

Quark AA - 1xAA light with 0.2, 3.5, 18, 70, and 90 lumens in addition to flashing modes. The XP-G R5 output is 0.2, 4, 22, 85, and 109 lumens.

Quark AA² - 2xAA light with 0.2, 3.5, 18, 70, and 170 lumens in addition to flashing modes. The XP-G R5 output is 0.2, 4, 22, 85, and 206 lumens.

Quark AA² Turbo - Comes with a larger, deeper head for more throw and Cree XP-G R5 emitter. Offered only with a tactical user interface, the output levels are 0.2, 4, 22, 85, and 206 lumens in addition to flashing modes.

Quark RGB - 2xCR123A MCE head with 4 different color LED dies built in to give white, red, green, or blue output (emits from only one die at a time). Uses the regular Quark 123² body with modes controlled by twisting head loose and tight. Available in versions with regular or neutral white light in one of the dies. Announced in November 2009.

*Nominal S2 output is lower because it is measured using the ANSI/NEMA FL-1 standard. Actual output is 7% higher than R5 output.
