About SLL

The Society of Light and Lighting (SLL) is recognised as an authority on lighting and welcomes all who are interested in any aspect of the world of light, lighting and its design or application.

The SLL welcomes all those who are interested in any aspect of the world of light, lighting, and its applications. Lighting designers, consulting engineers, researchers, students, professors, manufacturers, sales staff; all contribute and all are members of the SLL.

Although the SLL was launched in 1999, the Society builds on 100 years of history. Its origins go back to the formation, in 1909, of the Illuminating Engineering Society, which had the aim of considering all applications of natural and artificial light.

The Society is part of the Chartered Institution of Building Services Engineers and offers the strength of a chartered professional institution with the freedom to serve the world of light and lighting without being restricted solely to engineering.

The aims of the Society are:

  • To be a at the forefront of utilising and developing light as an integral part of a healthy, ergonomic and sustainable future.

  • To promote the benefits of a good lighting, especially in the built environment.

  • To provide professional recognition to all those active in the field of light and lighting, including designers, engineers, academics and those in the supply chain.

  • To establish and promote good practice in lighting design and engineering, including daylight, in all their facets.

  • To provide a forum where people interested in all aspects of light and lighting can come together.

  • To set and maintain standards in education and competence for light and lighting.

  • To assist and advise government and other authoritative bodies on the best use of and application of light and lighting.
