Abstract: A lighting fixture includes a fixture housing. A circuit board is positioned in the fixture housing. The circuit board includes a driver circuit. A plurality of light emitters are disposed on the circuit board. The light emitters are operatively connected to the driver circuit to produce a light output. A temperature sensor is disposed on the circuit board, the temperature sensor configured to measure a temperature of the circuit board and output a signal. The driver circuit is configured to reduce the light output in response to the signal from the temperature sensor.

Abstract: A recessed luminaire includes a housing supporting a light emitter, an intumescent material coupled to an outer surface of the housing, and a plate coupled to the housing and to the intumescent material. The housing configured to be positioned at least partially through a ceiling. The housing also includes a stepped surface. The intumescent material has a shape complementary to a shape of the housing. The plate is positioned adjacent to the stepped surface and to an upper surface of the intumescent material.

Abstract: A light fixture includes a housing for supporting a light source and an enclosure for supporting a driver in electrical communication with the light source. The enclosure is selectively supported in one of a first position and a second position while maintaining electrical communication between the driver and the light source in both positions. The enclosure is directly coupled to the housing in the first position, and the enclosure is supported separately from the housing in the second position.
