Petzl Reactik

Price: £65.00


New for Autumn 2016 -

The all new Reactik is here - a torch that reacts to ambient light as you explore, meaning that battery life is preserved as the torch adjusts itself according to the conditions.  Stare down at a map up close - light is reduced until you look ahead once more.  Among other runners, each with their own lights, the Reactik dims intuitively and preserves burn time.

The built-in sensor can be overridden, for times when you know it's full power all the way, so it won't let you down.  And it'll resort to a safe level of light for an emergency walk, if you're unfortunate enough to burn through the entire battery before calling it quits.  Though after an available 12hrs burn time, a walk would likely be welcome!

Petzl say:

Compact, rechargeable and intelligent headlamp with REACTIVE LIGHTING technology that automatically adjusts brightness to the needs of the user. 220 lumens

With 220 lumens of power, the REACTIK headlamp is ideal for dynamic, intense activities. With REACTIK, the user wears a compact, rechargeable headlamp that is above all intelligent, with REACTIVE LIGHTING technology. During activity, thanks to a sensor, REACTIK analyzes the ambient light and adjusts the brightness instantly to user requirements. Battery life is optimized and the manipulations are reduced to a minimum!

Available in Blue (pictured).
