NEMA Releases New Standard for Street and Area Lighting

The National Electrical Manufacturers Association (NEMA) published American National Standard for Roadway and Area Lighting Equipment—Metering Performance Requirements for LED Drivers with Integral Energy Measurement (ANSI C136.52-2021). This new standard establishes acceptable metering performance criteria for LED drivers with built-in (integral to the driver) energy consumption measurement functionality for use in outdoor luminaire applications. It describes two metering device performance levels for roadway and area lighting applications: 2% Accuracy Class and 5% Accuracy Class.

This standard is written for use by roadway and area lighting component manufacturers, municipal and regional governments specifying outdoor lighting solutions, and street lighting offices/bureaus. ANSI C136.52-2021 is available on the NEMA website for $70.
