DESIGN AWARD Winner 2024 The Kalkhoff Light Series has been honored with a prestigious iF DESIGN AWARD. Its straightforward design and well-thought-out product concept impressed the expert jury. With minimal weight (starting at 20 kg) and practical features, the Light Series offers the best of both worlds. The powerful Bosch Performance Line SX drive (55 Nm) with an integrated 400 Wh Bosch CompactTube battery provides all-day power – the optional Range Extender adds an additional 250 Wh of battery capacity.
