Overview
SIST EN IEC 63356-1:2026 – LED Light Source Characteristics – Part 1: Data Sheets is a CENELEC (CLC) European adoption of the IEC standard for the specification of data sheets for LED lamps and LED modules. This third edition standardizes the essential parameters that must be included in LED light source data sheets, facilitating product interchangeability between manufacturers and supporting harmonization in the lighting industry. SIST EN IEC 63356-1:2026 replaces the previous 2023 edition, introducing notable technical updates, such as the addition of data sheets for GJ6.6d-2-x capped LED lamps.
By defining a structured format with specified parameters for each sheet, the standard delivers clarity and consistency within product information. It is designed to complement related safety and performance requirements by referencing IEC 62031, IEC 63554, and IEC 63555 for compliance criteria.
Key Topics
-
Standardized LED Data Sheets:
SIST EN IEC 63356-1:2026 details which product parameters must be provided on the data sheet for each type of LED lamp or LED module. Parameters cover mechanical, electrical, and optical characteristics.
-
Data Sheet Numbering System:
The standard defines a clear numbering convention. Data sheets are grouped by lamp/module type (e.g. single-capped, double-capped; non-integrated, semi-integrated, integrated), ensuring easy identification and traceability.
-
Product Interchangeability:
By harmonizing key data sheet parameters, the standard enables LED light sources from various manufacturers to be used interchangeably in luminaires and systems, supporting market flexibility.
-
Updates with New Cap Types:
This edition includes significant updates, including new data sheets for GJ6.6d-2-x capped LED lamps, broadening product coverage in transport and general lighting.
Applications
SIST EN IEC 63356-1:2026 offers direct practical value by:
- Supporting Manufacturers: Provides a clear template for manufacturers to present technical data for LED lamps and modules, ensuring product information meets harmonized industry expectations.
- Facilitating Procurement: Simplifies the process for specifiers, buyers, and lighting professionals to compare products from different providers, as all products list the same required parameters.
- Enabling System Design: Ensures controlgear and luminaire designers have the standardized data needed for safe and effective system integration.
- Enhancing Quality Assurance: Helps ensure that products meet minimum interoperability requirements, supporting reliability in installations ranging from residential to commercial and transport environments.
- Promoting Interchangeability: Reduces risk of supply chain issues by making it practical to substitute equivalent LED light sources without technical barriers.
Common settings where this standard is applied include:
- General lighting for commercial, residential, and street applications
- Transport lighting, including specification of double-capped lamp data for rail, automotive, and aviation
- Product catalogs and technical datasheet management
Related Standards
SIST EN IEC 63356-1:2026 works in coordination with several other international standards tailored to LED lighting safety and performance:
- IEC 63554 – Compliance criteria for safety related to data sheet parameters
- IEC 62031 – Safety requirements for LED modules
- IEC 63555 – Compliance criteria for performance requirements
- EN IEC 63356-2 – Design parameters and values for LED light sources (complements Part 1 by specifying design aspects)
- IEC 62931 – Previous technical references for specific LED lamp types
Adhering to SIST EN IEC 63356-1:2026 enhances transparency, safety, and market access in the rapidly evolving field of LED lighting technology by providing a common reference for technical product specification. This standard forms a foundation for further digitalization and quality management in the lighting industry.
