In 2002, the Committee for European Standardisation (CEN) took on the tasks of harmonising the lighting recommendations. The result of this is a range of European Standards in place (BS EN series in the UK) that specify the lighting requirements for a wide range of applications.

The role of the SLL Code for Lighting has therefore changed from being the only source for quantitative lighting recommendations to now being a guide on how to interpret the BS EN recommendations and how to put them into practice.

Updates to the code.

The new 2022 edition of the SLL Code for Lighting acknowledges the dominance of the LED technology and the non visual effects of lighting.

This edition of the SLL Code for Lighting covers:

  • The effects of lighting on task performance, behaviour, safety and health, as well as the financial and environmental cost

  • How the UK recommendations should be interpreted and what the CIBSE recommended lux levels are

  • Detailed description of all calculations required for quantitative lighting design

  • The standard covers all aspects of lighting, including Road lighting. In our overview, we will focus on workplace lighting and CIBSE recommended lighting levels
