Surefire M640DF Turbo

 The M640DFT-PRO is roughly the same size as their non-Turbo counterparts. It securely mounts to M-Lok or Picatinny rails and delivers 1,000 lumens and 100,000 candela of high-intensity light. Dual Fuel allows you to use a rechargeable 18650 battery or CR123 lithium batteries.
