1. A lighting fixture comprising:
a fixture housing;
a circuit board positioned in the fixture housing, the circuit board including a driver circuit;
a plurality of light emitters disposed on the circuit board, the light emitters operatively connected to the driver circuit to produce a light output;
a temperature sensor having a sensor body, the temperature sensor connected the circuit board and configured to measure a temperature of the circuit board and output a signal; and
a reflector having a reflector body and a sensor opening, wherein at least a portion of the temperature sensor extends through the sensor opening and at least a portion of the sensor body is separated from the circuit board by the reflector,
wherein the driver circuit is configured to reduce the light output in response to the signal from the temperature sensor.
