1500 Lumen Dual Fuel Surefire Scout Weapon Light

The Surefire Scout 640DF puts out 1500 lumens of white light with 16,000 candela. This high output weapon light features a hybrid beam shape, with a clearly defined hot spot that throws out to 250 meters, with enough ambient spill to illuminate your surroundings. The 640DF also includes mounts for Picatinny and M-LOK rails, as well as a reliable click tailcap and rechargable SF18650B battery.

Rechargeable Surefire Scout Light

The biggest advantage of this light is how it feeds – from a single rechargeable battery, or from two reliable 123A batteries. The 640DF includes a SF18650B lithium ion battery, which you can recharge with an included micro USB cable. No dedicated chargers needed, just plug the cable into the battery and let it charge up.

Features

  • Dual fuel light — can be powered by an SF18650B lithium-ion rechargeable battery or two 123A lithium batteries
  • Generates up to 1,500 lumens of TIR-focused light with included SF18650B or 1,200 lumens with 123A batteries
  • Versatile Low-Profile Mount (LPM) allows the user to optimize the light’s position relative to the rail
  • Virtually indestructible ultra-high-output LED
  • TIR lens shapes beam with defined hot spot, with enough reach and surround light for close-to longer-range operations
  • Activation via Z68 momentary or constant pushbutton switching with protective shroud
  • O-ring seals keep out moisture; the Scout Light Pro is IPX7 rated
  • Includes mounting hardware for Picatinny and M-LOK rails, and (1) SF18650B rechargeable lithium-ion battery
