HPS or high-pressure sodium lamps are the most efficient part of the HID where a few degrees of color performance are important. Standard HPS lamps make a golden white light if they reach complete brightness. Many recognize them as the familiar golden light from street lights, one of their principal applications. There are many HPS lamps made for indoor utilization with improved color compared to standard HPS lamps, but the improvements come at the cost of shorter lamp life, as well as lower efficacy. These lights are nowadays an accepted source of light in industrial plants, as well as being utilized in many institutional and commercial applications.

Benefits
- Most well-organized member of the family of HID light, seven times as methodical as incandescent, as well as over two times as structured as mercury vapor.
- The warm-up time is 3 to 4 minutes, which is somewhat less than that of mercury vapor or metal halide lamps.
- Long lamp life- 24,000 hours.
- Excellent lumen maintenance.
- Wide range of light types with wats ranging from 35-1000 watts.
- Many HPS lamps are able to function in any position.
Disadvantages
- The light produced is a golden white color, which may not be appropriate for certain applications.
- Requires a ballast.
- Once started can take from five to ten minutes to reach the full light output. They also require at least a one-minute cool-down to re-strike.
- End-of-life gets characterized by off-on cycling, as well as continued operations are able to damage the lamp ballast when not replaced quickly.
Applications
High-Pressure Sodium lamps are recommended in a wide variety of applications including industrial, commercial, street, as well as security lighting. The lamps are very efficient if compared to fluorescent and incandescent and that creates them suited particularly for energy coherent applications.
The wat at which the HPS lamp function varies from its general rating based on the equipoise, the supply volt, the lamp volt, as well as the fixture style. When strategizing an HPS setup, it’s vital to take these changeable into account since the lumen result of the lamp differs from the wattage.
Anyways of operating function, High-Pressure Sodium lights produce similar lumen output. The location also has no effect on other lamp operating characteristics.
With the right loads, High-Pressure Sodium lights can begin at surrounding temperatures around -40F, as well as even lower. The HPS lamps get designed so that, once the arc gets established, they are going to warm up into full wat, and light output at any temperature.
