The Ledlenser K2 is a high-quality LED Mini Key-Light made from strong aircraft-grade aluminium. Though compact, it is a touch larger than some other micro-sized lights and this extra size equates with bigger output: a beam distance up to 20 metres with a maximum 20 lumens brightness. The torch is a helpful source of everyday short-distance light, which is useful for finding things hidden under the bed, for lighting up keyholes or even checking footing in slippery conditions. Turn it on with a deliberate twist-action, a feature which makes it less likely to come on by accident in a pocket. Even if it does the generous 4 hour run time should keep this mini key-light going for longer than others. One-year warranty.
