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 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.
