The lighting fixture which comprises an elongated housing having a top wall and a bottom wall. The width of the top wall is greater than the width of the bottom wall, which has a free edge located below the top wall providing an opening for the emission of light from at least one light bulb mounted in the housing and projecting beyond the free edge of the bottom wall. A reflector is mounted in the housing and has a reflector wall located between the top wall and the at least one bulb. The reflector has a plurality of air vents formed in it and the top wall of the housing also has a plurality of vents formed therein, offset from the air vents in the reflector wall, whereby air below the reflector wall heated by the bulb flows through the air vents in the reflector, and out the air vents in the top wall, but the emission of light through the top wall is blocked.
