SMALL PROFILE LUMINAIRE HAVING ADJUSTABLE PHOTOMETRIC DISTRIBUTION

摘要

A horticultural luminaire is described in which a lamp is contained within a first compartment and a ballast unit is contained in a second compartment. The ballast unit is in heat-conducting contact with the top of the unit and a plate member also covers the ballast unit to act as an additional heat sink. The top of the luminaire housing may be provided with bracket members to facilitate mounting of the luminaire on a structural I-beam.
