The Klarus A2 Pro torch has a maximum output of 1450 lumens from the LED and is powered by an included 21700 li-ion which is rechargeable via the USB-C port. Alternatively, the light can use 1 x 18650 or 3 x AAA cells in an emergency, but please do not recharge the torch unless using a 21700.

The A2 Pro can be adjusted between floodlight and spotlight, with a maximum beam distance of 420 meters. Ideal for a range of applications, the flashlight has three brightness levels and a strobe output.

To switch between the flood and spot modes, simply extend and retrace the head of the light. The side switch allows selection between the brightness levels. Built-in to the side switch is a battery indicator which shows the remaining capacity at a glance:

• Green = between 30% and 100%
• Red = between 10% and 30%
• Flashing Red = lower than 10%
