Energy Reporting Requirements for Lighting Devices
This Standard specifies the minimum performance requirements for lighting devices that report energy data. These requirements include the specific energy data types to be reported, the nominal and statistical accuracy performance for all reported data types, and references to other Standards that define the information model for all data types. Lighting devices addressed by this Standard include AC and DC powered light sources (including both integral replacement lamps and luminaires); LED drivers and other integral or remote power sources; lighting system or device controllers; and associated user interface devices. Energy metering devices, such as sub-meters for buildings, are excluded from the scope of this Standard.
