A light fixture with self-test ability of sealing includes a light head with a head housing, a light source for emitting light and generating heat, and a temperature sensor and an air pressure sensor for respectively detecting the temperature and air pressure inside the head housing are provided in the head housing. A controller is further included for determining the sealing performance of the head housing based on the detection results of the temperature sensor and the air pressure sensor. The head housing is provided with a waterproof breathable valve allowing the internal space of the head housing in air communication with the external space of the light fixture. A switch is configured which is capable of switching between two states by unblocking/blocking the waterproof breathable valve to make the internal space of the head housing in air communication with the external space of the light fixture or not.
