The Olight Valkyrie uses two side by side CR123A batteries in common form factor to the industry for a known and comfortable feel. The light features a TIR optic lens providing a 245-meter-long focused beam that is still wide enough to see all around you to eliminate any blind spots in the dark. The heavy duty quick attach and release mounting system allows the light to have a tight hold on any firearm with a Picatinny or Glock style rail.
The PL-2 Valkyrie is a highly powerful light offering an extremely long distance that is suitable for use on rifles like the AR-15. Moreover, there is no need for additional cables and switches. It works wonderfully like it is.
