The Ledlenser K2, with up to 20 lm1 and a lighting distance of up to 20 m1 , is the most powerful model in the K-Series.

However, this 5.2 cm light only weighs 20 g. And while we're at it with impressive figures: its 4 button cells last up to 4 hours1.

To ensure that the battery lasts this long, a twist mechanism prevents it from being unintentionally switched on in your trouser pocket.
