High power in a small housing! The K4R is a key ring lamp raising performance, technology and design up to a new level. The small everyday helper in a high-quality and well-designed aluminium case reaches up to 60 lumens and provides wide area illumination. Being the first lamp in the K series, the K4R is rechargeable as well as equipped with an additional safety feature emitting an SOS (hold switch for 3 seconds) distress signal if necessary.
