[[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.  

'''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.

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).  

'''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 OTF lumens in addition to flashing modes. In December 2010, a limited run of satin finish (bead blasted) titanium 123² Turbo's with XP-G S3 bin LED's was introduced (also MiNI 123's).

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.
