A high PAR maintenance rate type high pressure sodium lamp with an auxiliary starting switch is provided with an external glass tube and a discharge tube which is arranged at the center in the external glass tube and coaxial with the external glass tube. The surface of the discharge tube is provided with a metal lead. The left and right ends of an external glass shell are provided with pressure sealing plates which are fused and sealed through high temperature. The pressure sealing plates are internally provided with conductive sheets. One end of the discharge tube is connected with the conductive sheet of the left end through a left internal conductive support, and the other end is connected with the conductive sheet of the right end through an auxiliary starting switch component. According to the high pressure sodium lamp, the high pressure sodium lamp can be quickly lit up through a temperature controlled switch so that the high pressure sodium lamp has the advantages of being great in starting performance, great in lighting effect, high in stability, long in the service life, great in high temperature resistance and high pressure resistance and safe and reliable and is not liable to crack.

A series (e.g., string) of flashing lights can temporarily blind animals that view the lights within about 25 feet of the lights, deterring them from even approaching the series of flashing lights. The series of flashing lights is placed about the perimeter of an area to be protected. In one embodiment, the flashing lights are gas discharge bulbs connected in series and driven by an electric fence charger.
