High Pressure Sodium Lamp (Twin-ARC Tube)
Sodium Lamp (HPS) is a version of a LPS light, came nearly 30 years after the development of the LPS and is a result of development of an arc tube to that can withstand sodium at high pressures. Most HPS lights need an igniter to provide a starting voltage of 2.5kV or more to start up. Our high pressure sodium lamp products contain additional elements to standard mercury lamps, and the size of the product is even smaller than regular mercury lamps. It has various color transformations, which make colors of objects under to become more distinguished.
Sodium lamp products have become extremely popular everywhere because of its 90-140 Lumen per Watt efficiency. A standard HPS light products a golden colored light with a CRI around 20 and a color temperature of 1900-2100K. Modern HPS lights are manufactured with a higher color temperature and an improved CRI. The high pressure sodium lamp is often preferred over standard mercury lamps for general indoor lighting due to wide color-temperature range produced and remarkable effect on cost saving by reducing the turnovers of the lights.
In addition to the advantages above, the high pressure sodium lamp products are very efficient lighting elements that have also been broadly used for outdoor lighting like streetlights and security lighting. The product is always a brilliant light solution. Please contact us today for specifications and quotes on our products.
