Low Pressure Sodium Lamp

Low Pressure Sodium Lamp: 1.Solar energy powered 2.High light efficency & little attenuation 3 Maintanence free gel battery

Low Pressure Sodium Lamp

The birth of low pressure sodium lamp is a revolution for outdoor lighting, especially for solar street lighting. Comparing with the same intensity routine light sources, Low-pressure sodium lamp can save up 50% electricity .Because of its tube is sealed and in a vacuum class shell coated with infrared reflection film, the lighting effect is not affected by ambient temperature. The characteristic perform pure radiation spectrum, stable ray. The wavelength has a strong penetrability in mist. With electronic ballast, the LPS Lamp is suitable for solar street lighting, channel lighting etc.
