Powerful and yet economical LED luminaires providing rotationally symmetrical illumination of ground surfaces. The lighting concept of these new bollards is based on built-in LEDs and a BEGA precision reflector module. Product design and construction of the luminaires are the result of the consistent practical realization of this new lighting development. The ultimate lighting and design quality of these luminaires make new lighting concepts possible. These new luminaires are defined by their high luminous efficiency, extremely long life and uniformity of illuminance.
