High Pressure Sodium (HPS) street lights are one of the most common street lights you can see today. They produce a distinctively yellow-orange, monochromatic glow.
You can still see many HPS lights for lighting large areas, manufacturing sites, roadways, parks, and parking lots. They are also commonly used as grow lights for plants. But today, HPS street lights are quickly being retrofitted with more efficient and eco-friendly LED lights.
Best Uses of HPS Street Lights
Since HPS street lights have high intensity lights, they are best for tall mounting applications like for industrial lighting and security lighting. They are the best options when you need to mount street lights with 15 feet and above heights.
They are not suitable for applications needing high color rendition accuracy, like in retail and commercialize lighting. HPS lights would do poorly on projecting the colors of objects with high precision. If street lights are to be switched on and off frequently, HPS lights are also not appropriate for the job. This is where LED street lights are best at.
