[[File:Quark-123-2.jpg|thumb|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.
