What are the lighting standards for a library?

The lighting standards for libraries are established to ensure that the lighting in these spaces supports the primary activities that take place, such as reading, studying, and research.

Several sources provide guidance on the recommended lighting levels and other factors to consider when designing the lighting for libraries. Here are some of the key standards and recommendations:

IS 2672 (1966): 

Code of Practice for Library Lighting: This Indian standard provides recommendations for the levels of illumination to be achieved by general principles of lighting for both public and institutional libraries.

Adequate Lighting Levels: 

It is recommended that luminaires in libraries provide 200 lux at bookshelves and 500 lux in reading areas, with a uniformity ratio of 0.60. This ensures that the lighting is sufficient for reading and studying, with a good balance of light across the space.

Color Rendering Index:

The color rendering index (CRI) of the light sources should be 80 and above. This is important for accurately rendering the colors of book covers and other materials, enhancing the visual appeal of the space, and preserving the integrity of valuable literary resources.

Unified Glare Rating: 

The unified glare rating (UGR) should be taken as 19 or less. This ensures that the lighting is soft and glare-free, creating better visual conditions for reading and studying.

EU Standard UNE 12464.1: 

This European standard on indoor lighting applies to libraries and recommends both quantitative and qualitative compliance with two important aspects: visual comfort and color rendering. It also covers maintenance, the lifespan of materials and devices, and even cleaning
