ABSTRACT:
A fitting for horticultural illumination includes a reflector and a housing for auxiliary equipment, the reflector being attached to the housing by a universal coupling so that the reflector can be exchanged for a reflector with other properties, thereby reducing investments when crops are changed. According to a preferred embodiment the reflector includes a collar adapting it for coupling with the housing. Both the collar including the reflector and the housing are suspended by a profile, thus forming a pre-assembled unit which is suspended by hooks from a rail provided in the greenhouse to be illuminated.
