The reduced form factor of the Tungsten is made possible by a revolutionary new light engine. ASP research developed a unique technology which produces brilliant white pre-focused light. A constant current driver is combined with a mathematically precise collimating cone to achieve unparalleled output. Advanced optics are coupled with precise machined high strength aerospace aluminum. All surfaces are then anodized with a proprietary Type III matte black hardcoat finish.
Powered by two high density, leak proof CR123A Lithium power cells, Tungsten lights have a glass lens, aluminum reflector and three position switch. A center locking position guards against accidental activation. Turned to the right, the switch provides constant illumination. To the left it is intermittent. A clip groove is machined into both the lens and switch end of the light. The included Snap-Loc Clip snaps into either groove.
