  • Diffuser filter

  • Headstrap


Headstrap Dimensions

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.
