The Powertac E9RG4 is perhaps the best all-around “duty” light on the market today. It features a one-handed operation to control four brightness levels and has a direct-to-strobe function. The 2500-lumen output is blinding and the beam is wide enough for superior situational awareness. For convenience, the E9RG4 is USB-rechargeable via magnetic cable. Small size, superior performance and long runtime makes the E9RG4 a favorite of police officers.
