Alternatively the light can be powered using 2 x CR123 or RCR123 cells with the included battery magazine.

A compact, palm-sized torch, the E4K offers fantastic performance, making high power and excellent specifications possible for everyday carry as well as specific applications, such as trekking and camping.

The E4K is constructed with a CNC machined unibody, making it lightweight, solid and offering excellent heat dissipation. The torch features anti-skid knurling for comfortable grip and cooling fins at the head of the light to reduce weight and for fast heat dissipation.
