As well as high efficiency, LEDs offer the advantage of generating light that can be very precisely directed. Modern floods, spots and LED light lines can thus cast architecturally interesting buildings in the right light with virtually
no light radiating into the night sky.
Additional savings potential can also be tapped in exterior lighting by lighting management. For example, street lights can be conveniently maintained by telemanagement. And when traffic volumes are low, luminous flux along arterial roads can be lowered
– within the limits set out in standards
– and thus adapted to actual requirements.
