ANSIlumensid

ANSIlumensid is a technical specification that defines a standardized identifier and metadata schema for light-emitting devices and luminaires. The format is intended to encode key photometric and product attributes—such as luminous flux, color characteristics, beam geometry, power consumption, and manufacturer information—into a compact, machine-readable identifier. It is used to facilitate inventory management, performance comparisons, and automated lighting control in commercial and industrial settings.

The specification organizes data into a hierarchical code and an associated metadata payload. The code portion provides a human-readable shorthand for core parameters (for example, lumen class, color temperature band, and delivery form), while the metadata payload uses a structured format to carry detailed measurements, test conditions, and certification references. Optional fields accommodate accessory compatibility, dimming profiles, and end-of-life recycling information.

ANSIlumensid was developed to address interoperability challenges across lighting products and software systems. Implementations typically integrate the identifier into product labels, digital catalogs, and building management systems, enabling filtering, compliance checks, and more accurate energy modeling. Several lighting manufacturers and software vendors have published draft mappings to the schema to support supply-chain transparency and automated procurement.

Critics note that widespread utility depends on consistent measurement procedures and industry adoption; discrepancies in test methods or voluntary compliance can limit the identifier’s effectiveness. Ongoing work focuses on aligning the schema with international photometric standards and developing tools for validation, translation, and secure distribution of identifier records.
