Reviewed by Darren, Shrewsbury. - 11th Nov, 2020 A lightweight, easy to use, hybrid 3xAAA or Core headtorch This lightweight, comfortable, easy to use, hybrid head torch from Petzl uses 3xAAA batteries or a usb rechargeable Petzl Core battery block. It is reasonably bright and lasts a reasonable time. Ideal for an evening walk, at dusk or just for an early morning dog walk. Always useful, in your rucksack, if you are later out on the hill, than planned, but would be even better, if it was able to be locked off, so not accidentally switched on in your rucksack, unless you carry spare batteries, or as a back up to a Petzl Actik Core!
