A lighting fixture includes a solid-state lighting source, such as an LED light source. A control module of the lighting fixture uses temperature sensing circuitry to determine a relative ambient temperature. When the ambient temperature is above a defined ambient temperature threshold, a drive signal is provided to the solid-state light source at a target drive level that corresponds to a normal light output level. When the ambient temperature is below the ambient temperature threshold, the drive signal is provided to the solid-state light source at a reduced drive level, which is lower than the target drive level.
