The Nitecore P18 torch has a maximum output of 1800 lumens from the Cree XHP35 HD LED and is powered by an included 1 x IMR 18650 battery. 

The innovative flashlight has a unibody, die-case design with a silent tactical switch and an independently controlled red LED. Constructed from aero-grade aluminium alloy, the P18 is lightweight and extremely durable. 

The silent tactical tail switch operates the five brightness levels, three special modes and momentary on and the side switch controls the auxiliary red LED. The red light is ideal for protecting night vision, making it suitable for outdoor, tactical and law enforcement applications such as equipment checks and map reading. In addition, the red LED is able to indicate the remaining battery power.
