The Ledlenser K4R is a stylish and compact rechargeable key ring torch that has a maximum output of 60 lumens from a COB LED.
The battery is charged using the included USB cable that plugs into the circular charging port on the base of the light. Simply plug the cable into the torch and connect the other end to a USB power source, then the charging indicator next to the port will illuminate red to show charging is in progress and will turn green once charging is complete.
A single push-button operates the torch, with one press turning it on to provide wide-angle illumination and a second press turning it off again. The K4R also has an SOS function that can be activated by holding the button down for 3 seconds.
For easy carry, the light features a small carabiner clip to attach it to your keys, so it is always to hand when you need it.
Please note that the K4R is not protected against water ingress, so it is not advised to use the torch in wet conditions or in areas where it can be potentially dropped in water.
