Low Pressure SOX Lamps
Operating at a wavelength close to the peak sensitivity of the human eye, these Low Pressure Sodium lamps provide the highest luminous efficiency of any general purpose lamp. SOX lamps emit a yellowish-orange light and are consequently only suitable for use where good colour discrimination is not required. They are particularly suitable for use where long operating hours are required. SOX lamps are generally employed in amenity applications, primarily because they are the most efficient light sources available - they deliver more lumens of light for each watt of power consumed than any other type of lamp.
