European foreword
This document (prEN 16163:2023) has been prepared by Technical Committee CEN/TC 346
“Conservation of Cultural Heritage”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
This document will supersede CEN/TS 16163:2014.
prEN 16163:2023 includes the following significant technical changes with respect to
CEN/TS 16163:2014:
since the publication of the CEN/TS 16163 in 2014, the technology of lighting has evolved considerably
and an update of the content has proven to be necessary. In addition to taking into account
technological advances and new calculation methods in the field of lighting in recent years, the present
version of prEN 16163 contains the elements of good practices for the exhibition lighting design, in its
subjective form, as an element of museography, which had not found its place in the previous version.

Introduction
Lighting is needed for many specific functions in museums and other cultural heritage buildings, such as
research, conservation and permanent or temporary exhibitions. Lighting is one of the most important
factors enabling visitors to fully enjoy works of art and other cultural property. In fact, lighting is a key
medium in which visitors interpret and appreciate cultural heritage. Light is needed to see well but this
may present a challenge when what is being viewed will deteriorate in the presence of light. When
displaying exhibits as a part of Cultural Heritage, it is essential to consider a controlled use of light, to
preserve them for the future generations. Indeed, light is an environmental factor, which is a threat to
many objects. Alone or in combination with other environmental factors (temperature, humidity,
pollution, etc.) light causes fading, discoloration and embrittlement of a wide range of materials. This
damage is cumulative and irreversible: no conservation treatment can restore original appearance of
colours and the material characteristics. Therefore, the challenge of museum exhibition lighting is to
find an appropriate compromise between the long term preservation of the object and the needs of
visitors to view them within a suitable exhibition design. As an integral part of exhibition lighting, the
following aspects should be considered, mentioned below without priority:
— the conservation aspect, related to the sensitivity of the exhibit at different wavelengths of the
incident radiant energy, the spectral composition of the light source and the total luminous
exposure,
— the visual aspect, related to the impact of lighting on the visitor experience: lighting has to allow
visitors to see exhibits on display, with the correct colour perceptions without glare, reflections or
insufficient illumination.
— the design aspect related to the concept and position of the exhibition architecture, the point of
view of the curator and all others involved in the purpose and/or didactic objectives of the
exhibition.
This document uses terms defined in European and International (CIE International lighting
vocabulary) terminology standards, but their definitions have been adapted to the intended users of
this specification.

1 Scope
This document defines the procedures as well as the means to implement adequate lighting, with regard
to the exhibition lighting and the conservation policy. This also includes security and cleaning lighting.
It takes visual, exhibition and conservation aspects into account and it also discusses the implications of
the lighting design on the safeguarding of cultural heritage. This document gives recommendations on
luminous exposure values. It aims to provide a tool for setting up a common European policy and a
guide to help curators, conservators and project managers to assess the correct lighting that can ensure
the safeguarding of the objects. This document covers indoor lighting for heritage objects on exhibition
in both public and private sites and does not consider lighting in other cultural heritage contexts such
as open-air collections, etc.
This document does not cover back of house activities such as conservation-restoration, storage,
emergency lighting and research.
