SOX Low Pressure Sodium Lamps

Since these lamps produce light at only one wavelength in the yellow region of the spectrum, they are used where energy efficiency and long life are the only requirements.

SYLVANIA SOX low pressure sodium lamps as very energy efficient , have an average rated life of 18,000 hours. They emit a characteristic yellow light that is ideal for certain street and area lighting, such as tunnels and viaducts. Since they product light at only one wavelength in the color spectrum, they have virtually no significant color rendering capabilities.
