The Modlite OKW-18650 Weapon Mounted Light Package contains an OKW light head, and 18650 body.  It also includes ONE 3500mAh 18650 battery and an (optional) Xtar charger  or tail cap or both. While lumen output is only 680 lumen the throw is about 400% greater than the Surefire M600DF.  This light head is best suited for situations where extreme throw is needed.

If you’re on the fence about which light head to purchase we recommend the PLH light package which is available here.


  • Hand assembled in and tested in the USA.
  • Lifetime guarantee
  • Approximately 680 out the front lumens and candela is approximately 69,000. It is an excellent overall light head good for indoor or outdoor use.
  • 6061 Series Alum bezel with Mil-Spec Hard Anodizing.
  • Ultra clear BOROFLOAT® lens allows 98-99% light transmittance.

Lithium CR123 cells are not supported and if used will cause the cells to heat up and possibly explode or catch fire. We recommend the KeepPower 18650 high drain cells which can be found here. Runtime is about 75 minutes with the supplied 18650 cells.

  1. woodruff.landon (verified owner)

    Very impressed with this light. Well made and super bright. If i purchase another (which is likely) i won’t pay extra to get the E-series tail cap and put that coin towards a unity gas cap.

  2. Heath Bratton (verified owner)

    Fantastic light, replaced a Surefire Scout Duel Fuel on my Recce set up.
