Full title and description

IEC 63403-2:2024 — Horticultural lighting - LED packages for horticultural lighting - Part 2: Binning. This international standard specifies the binning method for LED packages intended for horticultural lighting applications (bilingual English/French edition).

Abstract

IEC 63403-2:2024 defines measurement conditions and a standardized binning procedure for LED packages used in horticultural lighting. The document covers pre-conditioning and test currents, measurement of electrical and optical parameters, and binning criteria including forward voltage, photon flux and chromaticity (with separate guidance for narrow-band and achromatic emitters). The part is intended to support consistent specification, procurement and quality control of horticultural LED packages.

Scope

IEC 63403-2:2024 specifies the binning method for LED packages for horticultural lighting, establishing uniform measurement conditions (temperature, test currents, pre-conditioning), required measurements and the binning categories to be used for electrical and optical parameters. The standard addresses binning by forward voltage, by photon flux and by chromaticity, and includes separate provisions for narrow‑band and achromatic emitters. It is intended to be used together with the related specification-sheet part of the series.

Key topics and requirements

• Defined measurement conditions: reference temperatures, recommended test currents and pre‑conditioning procedures prior to measurement.
• Measurement procedures for electrical and optical parameters relevant to horticultural LED packages (including forward voltage and photon flux).
• Binning schemes and limits for forward voltage, photon flux (output) and chromaticity; separate chromaticity binning guidance for narrow‑band and achromatic emitters.
• Tables of recommended binning currents and normative terms/definitions to ensure consistent exchange of data between manufacturers, test labs and purchasers.
• Normative references and cross‑references to the specification sheet (Part 1) and established colorimetry standards where applicable.

Typical use and users

Primary users include LED package and module manufacturers, component test laboratories, horticultural lighting system designers, growers and procurement specialists who require consistent product information for specification and quality control. Standards bodies and certification organizations will use the standard as a reference for national adoption and for harmonizing test/labeling practices.
