An innovative system providing flat, indirect lighting. The light from the high-power floodlight is redirected by a square top reflector, producing particularly soft and uniform light distribution and optimum glare suppression. The floodlight and top reflector are exactly set to one another. The entire system can be infinitely adjusted in the bearings of the pole cap. Symmetrical light distribution is produced when the top reflector is set in a horizontal position, and asymmetrical light distribution when the top reflector is swivelled 0°-65°.
