Reviewed by Darren - 5th Apr, 2021 Bright, light and easy to use, rechargeable Petzl headtorch. This Petzl Actik Core hybrid headtorch is bright, lightweight, comfortable and easy to use. It has a lock off option, so it doesn't get switched by accident/drains, in your pocket or rucksack and works, when you need it to work! It has several brightness levels (up to 450 lumens bursts) broad and/or narrow beam, and red night vision option. It comes with a USB rechargeable Core Battery, but can also accept 3 AAA batteries too. A reliable main or simple, back-up headtorch, to keep safe, for when you need it, when a walk or run is longer than you planned/or for early/late starts/dark nights.
