Up- and Downlight - Telesto LED outdoor wall light The flat Telesto LED outdoor wall light has warm white LEDs that emit upward and downward light and not only provide adequate brightness, but also an interesting light effect on the house façade. The wide LED outdoor wall light is characterised by energy-efficient illumination as well as its self-cleaning function. The nano surface coating of the light results in the so-called lotus effect. Water trickles down the light in the form of drops and carries along smallest dirt particles and thus cleans the light automatically. Energy efficiency class:A+
