SIST EN IEC 63545:2026

Overview

SIST EN IEC 63545:2026 – Horticultural lighting – Luminaires for horticultural lighting – Safety is a European standard developed by CLC, adopting the international IEC 63545:2026 standard. This document specifies comprehensive safety requirements for horticultural luminaires operating at supply voltages up to 1,000 V. Focusing on horticultural lighting, the standard addresses the unique operational and environmental demands of equipment used to promote plant growth both indoors and in greenhouses, as well as other controlled environments. By implementing these safety requirements, manufacturers and users can minimize risks related to electric shock, photobiological hazards, dust and moisture ingress, and other specific concerns in horticultural applications.

Key Topics

• Safety Requirements for Horticultural Luminaires
  • Defines additional and deviated requirements compared to general-purpose luminaires.
  • Addresses protection against dust, moisture, and saline environments common in horticulture.
• Photobiological Safety
  • Specifies assessment procedures for photobiological risks such as UV and blue-light hazards.
  • Requires classification and marking of luminaires based on photobiological risk groups.
• Marking and Labelling
  • Details mandatory labels for risk groups, including required safety symbols and warning statements.
  • Ensures visibility and comprehension for installation and maintenance personnel.
• Instruction Manuals
  • Outlines essential information for safe operation, installation, and maintenance.
  • Emphasizes photobiological hazards and provides operational guidance for daily exposure limits.
• Environmental Resistance
  • Sets minimum Ingress Protection (IP) ratings for luminaires depending on their intended use:
    • At least IP65 for industrial/professional use; IP66 for inter-plant lighting; IP44 for household use.
  • Includes resistance to salt mist and requirements for withstanding high-humidity or corrosive environments.
• Electrical and Construction Provisions
  • Requirements for earthing, insulation resistance, protection against electric shock, and safe electrical connections.
  • Endurance and thermal tests to ensure safe operation, including temperature limitations for external surfaces.

Applications

SIST EN IEC 63545:2026 is applicable in various horticultural lighting scenarios, where luminaires are designed to directly influence plant biology through artificial lighting. Typical applications include:

• Greenhouses: Ensures that luminaires installed in humid, potentially corrosive environments meet stringent safety and durability standards.
• Plant Factories and Indoor Farms: Addresses the needs of high-density plant production with rigorous protection against dust, water, and human exposure.
• Research Institutions: Supplies standardized safety guidelines for controlled studies on plant growth and photobiological effects.
• Home and Consumer Horticulture: Provides a safety baseline for luminaires used in residential settings, ensuring minimal risk to ordinary users.
• Industrial and Professional Installations: Mandates higher IP ratings and professional supervision for luminaires used in large-scale or technically demanding settings.

This standard supports manufacturers, facility managers, and safety engineers in designing, selecting, and installing safe horticultural lighting systems.

Related Standards

To achieve full compliance, SIST EN IEC 63545:2026 is used alongside several related international standards, including:

• IEC 60598-1: Luminaires - General requirements and tests.
• IEC 60598-2 Series: Particular requirements for various luminaire types (fixed, recessed, portable, floodlights, rope lights, lighting chains).
• IEC 62471 and IEC 62471-7: Photobiological safety of lamps and lamp systems.
• IEC 60068-2-11: Environmental testing - Salt mist resistance.
• IEC 60730-1: Automatic electrical controls – General requirements.

SIST EN IEC 63545:2026 ensures that horticultural luminaires are safe, reliable, and suitable for the demanding conditions unique to plant cultivation. Adhering to this standard not only helps with regulatory compliance but also promotes user and plant safety and supports robust product performance in the fast-growing horticultural lighting market.
