The Quark series offers a staggering array of options, accessories and interchangeability. With a wide range of LED, battery and clip choices, you get the features you want without compromise. Available in a Pro multi-mode interface or a Tactical interface with programmable primary and secondary outputs, these lights can be used in a wide variety of settings and applications. Waterproof and constructed with aircraft-grade aluminum and impact-resistant lenses, Quark lights are tough enough to meet any challenge.

The Quark Tactical QTLC does not have a clip.

Note: Orders for this Gen2 light will occasionally ship in the Gen1 packaging, but will be designated by a silver "XP-G Gen2" sticker next to the barcode. In such instances, the product specifications on this webpage take precedence over the specifications on the packaging.

Quark Prism Kit

Included Parts

  • Optical prism enclosed in rubber case

  • Diffuser filter

  • Headstrap


Headstrap Dimensions

"Relaxed" - 23 inches, circumference

"Stretched" - 36 inches, circumference



The Prism attaches to any standard Quark bezel (does not fit the Quark Mini or Quark Turbo). It effectively angles your light 90-degrees, allowing you to use your flashlight hands-free from your belt, vest, or the included Prism headband.

The Prism kit includes a diffuser filter. This glass lens snaps into your Prism (look for the small rubber 'teeth') and diffuses the light into a spotless, even spread.
