Introduction
Formally titled Recommended Practice for Lighting Roadway and Parking Facilities, the RP-8-18 version represented a massive shift in how lighting standards were organized. Unlike previous editions that focused on individual segments of infrastructure, RP-8-18 is an aggregation of 12 previously distinct standards into one "comprehensive tome". ansi ies rp-8-18 pdf

- Lighting criteria: The guide provides information on how to determine the appropriate lighting levels for different types of roadways, based on factors such as traffic volume, speed, and road geometry.
- Luminaire selection: It offers guidance on selecting the right type of luminaire (light fixture) for a particular application, including considerations for energy efficiency, maintenance, and glare control.
- Installation and maintenance: The guide provides recommendations for the installation, operation, and maintenance of roadway lighting systems, including pole spacing, mounting heights, and aiming angles.
- Glare control: It discusses methods for minimizing glare from roadway lighting systems, which is essential for reducing visual discomfort and distractions for drivers.
- Horizontal illuminance: 2 – 10 fc (depending on activity level)
- Uniformity ratio (Avg/Min) ≤ 4:1
- Veiling luminance limits for entrance/exit transitions.
Finally, the day of the retrofit arrived. The team worked through the night, installing the new lighting system. And when the sun rose the next morning, the parking lot was transformed. The light was brighter, more even, and more energy-efficient.
