The Institution of Lighting Professionals

The Institution of Lighting Professionals is an open and collaborative organisation that works proactively with architects, interior designers and specifiers to integrate quality lighting into the built environment.

We promote best practice by uniting the skills of engineering, design and technology to deliver great spaces for people. Visit www.theilp.org.uk for more information.

The Society of Light and Lighting

The Society of Light and Lighting (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. The SLL is recognised worldwide as an authority on lighting and its applications.

Although the SLL was launched in 1999, the Society builds on over 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.

Benefits of membership include free online access and download of all SLL and CIBSE publications, free online access to the world-renowned peer reviewed Lighting Research & Technology Journal, SLL Newsletter and CIBSE Journal. Individual and company membership is available.

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.
