The revolutionary creation!! ¨C the development of the low pressure sodium lamp is a revolution among the outdoor lighting field, especially in the solar-energy lighting field. Compare with the ordinary light sources with the same luminous flux and light efficiency, the low pressure sodium lamp could save at least 50% of the electricity-energy. Because the arc tube of the low pressure sodium lamps is sealed inside the glass shells with the high vacuum and the reflection film of the infrared ray, so the lamp¡¯s light efficiency is not almost not affected by the outside environment temperature, its radialization spectrum is pure, smooth, no variedness light, the ray under such wavelength could penetrate through brume easily, if use such low pressure sodium lamp with the high quality electronic ballast, then this low pressure sodium lamp system could be used under the different power condition, especially be suitable for the use on solar-energy street light, tunnel lighting fixtures, and some special area like frigid zone and tableland etc.

Low Pressure Sodium Lamps

The Specification for Low Pressure Sodium Lamp

Note:: 18 to 55W low pressure sodium lamps could be used with our XH-1A street light fixture, and 60W to 135W could be used with our XH-1B street light fixture.
