Ledlenser K4R
Small light, big power: The K4R is a rechargeable keychain light with up to 120 lumens of light output, making it significantly brighter than most smartphone torch functions. No more messing with annoying cables as the light can be conveniently charged using the integrated fold-out USB-A interface. With its compacted brushed aluminum housing, the K4R combines a high-quality look and feel, making it an elegant and practical accessory for your key ring.

1Measured values according to ANSI/PLATO FL 1 at the respective setting. If no setting is explicitly named, the values for luminous flux (lumen/lm) and luminous range (metres/m) refer to the brightest setting and the values for luminous duration (hours/h) to the lowest setting. A boost function (if available) can be used several times, but is only available for a short time at a time. In case the lamp is equipped with coloured LEDs, the measured values are given with white light or the white LED. If the lamp has different energy modes, the "energy saving mode" is the basis for the measurement
