Amazing, I have already recommended to my cmdt in my firehouse. A must have product for firefighters.


The Nitecore MT21C flashlight has a maximum output of 1000 lumens from the Cree XP-L HD V6 LED and has a selection of battery options. Choose from 1 x 18650 Li-ion battery, 2 x RCR123 Li-ion batteries or 2 x CR123 single use cells.

The MT21C features a 90º adjustable head, creating a versatile 'L' shape which suits a range of applications. Keep the head flat for a streamlined everyday carry torch or adjust to make the ideal work light. The flashlight comes with a two way pocket clip so that the MT21C can be attached to your pocket, backpack or clothing for hands-free use. 

In addition to the pocket clip, the MT21C offers a metal loop which the light can be suspended with and a magnetic base for attachment to metal surfaces.
