LG14: Control of Electric Lighting

07 Sep 23

The Society of Light and Lighting (SLL) has launched the latest revision of SLL Lighting Guide LG14: Control of Electric Lighting. Initially published in 2016, this is the second edition of LG14. It sets out a logical approach for the professional designer to consider the consultation, design, specification, commissioning and handover of a lighting installation incorporating controls. 

Lighting control of electric light is not a new concept — lighting control in some form is as old as lighting itself. This second edition of LG14 has been produced and updated to inform what is meant by lighting controls for electric light relative to project specification and design in the 21st century. This guide covers internal and external electric lighting control but does not cover solar blind and shutter control, theatre or advertising electric lighting control. 

Luminaire technology, energy efficiency legislation and rising energy costs are the most common drivers for the incorporation of lighting controls into a project. This means that lighting controls are increasingly becoming essential rather than an ‘optional extra/nice to have’ project consideration. 

It is therefore an important consideration that the project stakeholders and, in particular, the lighting designer are aware of the current lighting control technologies available to meet the performance objectives of a project. This approach will enable the specification of lighting control products and services that are fit for purpose and compatible with the selected luminaires and lighting design.  

“Lighting controls are now an integral part of all lighting installations. Since its inception, LG 14 has been structured to guide the designer through the processes required to make informed decisions about how and why to add lighting controls to a lighting design. The chapter structure in LG 14 follows the usual path of the initial consultation with the client, through to commissioning & handover.” Sophie Parry, Trilux – Author and Technical & Publications Chair, SLL 

The author was Sophie Parry, Trilux, with case studies contributed by the late David Holmes and Simon Robinson (WSP Consulting). 

The SLL is a division of the Chartered Institution of Building Services Engineers (CIBSE). Members of CIBSE and the SLL receive unlimited online access to guides via the CIBSE Knowledge Portal.
