Overview

prEN IEC 63116:2025 - Lighting systems - General requirements is a European draft standard developed by the International Electrotechnical Commission (IEC) and the European Committee for Electrotechnical Standardization (CLC). It establishes the general requirements for the design, installation, and maintenance of both indoor and outdoor electric lighting systems. As the lighting sector advances toward integrated and intelligent solutions, this standard addresses fundamental aspects necessary to ensure safe, functional, and interoperable lighting systems suitable for various applications.

Adhering to prEN IEC 63116:2025 enables manufacturers, designers, installers, and facility managers to ensure compliance with up-to-date best practices and regulatory requirements in lighting technology. The standard is applicable to a wide array of lighting installations, except those used for stage and studio environments.

Key Topics

prEN IEC 63116:2025 covers essential aspects that underpin reliable lighting system performance and safety:

• System Definition: Clarifies what constitutes a lighting system, including luminaires, controls, interfaces, software, user interfaces, and networking elements.
• Product Compliance: Emphasizes that components used in lighting systems must comply with relevant product standards for safety, performance, and compatibility.
• Classifications of Lighting Systems:
  • Standalone luminaires
  • Autonomous lighting systems
  • Centrally controllable lighting systems
• Safety:
  • Electrical safety: Protection against electrical hazards during operation and maintenance.
  • Functional safety: Ensures correct system response to normal and abnormal inputs.
• Information and Cyber Security: Requirements for protecting lighting systems from unauthorized access, tampering, or data breaches.
• Installation and Maintenance: Guidance on proper setup, use, and ongoing care to maintain lighting system integrity.
• Performance and Functionality: Covers adaptive characteristics such as sensor integration, adjustable light output, and spectrum, as well as communication protocols.
• Instructions for Use: Ensures users are informed about safe operation, system interfaces, and maintenance needs.

Applications

prEN IEC 63116:2025 is designed to add value across a broad spectrum of lighting system applications:

• Commercial Buildings: Ensures reliable, energy-efficient, and safe lighting for offices, retail spaces, and public buildings.
• Industrial Facilities: Facilitates robust lighting systems for manufacturing, warehousing, and logistics centers, supporting occupational safety and process efficiency.
• Public Infrastructure: Applicable to street lighting, transportation hubs, and outdoor public spaces, enhancing security and visibility.
• Smart Lighting and IoT: Addresses integration with intelligent control systems, supporting automation, adaptive lighting, and remote management.
• Educational and Healthcare Environments: Promotes lighting quality and compliance in schools, universities, hospitals, and laboratories.

Following the standard supports interoperability, lowers maintenance costs, and mitigates operational risks. It also aids in meeting sustainability goals by addressing efficient system design and operation.

Related Standards

For comprehensive lighting system compliance and enhanced functionality, prEN IEC 63116:2025 references and aligns with several other key standards:

• IEC 62504: General lighting – LED products and related equipment – Terms and definitions
• IEC TS 63105: Lighting systems and related equipment – Vocabulary
• IEC TS 63117: General requirements for lighting systems – Safety

These referenced documents ensure consistent terminology, safety benchmarks, and performance criteria across all lighting system projects.

50 LIGHTING SYSTEMS – GENERAL REQUIREMENTS
52 FOREWORD
53 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
54 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
55 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
56 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
57 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
58 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
59 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
60 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
61 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
62 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
63 consensus of opinion on the relevant subjects since each technical committee has representation from all
64 interested IEC National Committees.
65 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
66 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
67 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
68 misinterpretation by any end user.
69 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
70 transparently to the maximum extent possible in their national and regional publications. Any divergence between
71 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
72 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
73 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
74 services carried out by independent certification bodies.
75 6) All users should ensure that they have the latest edition of this publication.
76 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
77 members of its technical committees and IEC National Committees for any personal injury, property damage or
78 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
79 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
80 Publications.
81 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
82 indispensable for the correct application of this publication.
83 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
84 rights. IEC shall not be held responsible for identifying any or all such patent rights.
85 IEC 63116 ED1 has been prepared by IEC technical committee 34: Lighting. It is based on IEC
86 TS 63116 ED1.1 with following major changes:
87 – Clarifying applicability of this document for outdoor and indoor lighting systems in scope;
88 – Reordering of clauses, placing clause 11 “Classification of lighting systems” at #5 and
89 shifting all other clauses 5 to 10 one position to clauses 6 to 11;
90 – Renaming clause 8 “Information security” into ”Information security and cyber security”
91 and amending its contents;
92 – Adding informative Annex A “Published documents for evaluating information security
93 and cyber security needs”; add the listed publications to the Bibliography
94 – Shifting the original Annex A to become Annex B.
95 The text of this International Standard is based on the following documents:
Draft Report on voting
34/xxx/FDIS 34/xxx/RVD
