SLL launches revised LG14 guide for control of electric lighting

Updated publication covers internal and external controls

A new publication offering updates on internal and external electric lighting control has been published by the Society of Light and Lighting (SLL).

The second edition of LG14: Control of electric lighting, originally published in 2016, sets out a logical approach for the professional designer to consider the consultation, design, specification, commissioning and handover of a lighting installation incorporating controls.

The guide has been updated to inform what is meant by controls for electric light relative to project specification and design in the 21st century. It covers internal and external electric lighting control, but does not cover solar blind and shutter control, or theatre and advertising electric lighting control.

Luminaire technology, energy efficiency legislation and rising energy costs are common drivers for incorporating lighting controls into a project. This means they are increasingly becoming essential, rather than an optional extra or ‘nice to have’.

‘Lighting controls are now an integral part of all lighting installations. LG14 guides the designer through the processes required to make informed decisions about how and why to add lighting controls to a lighting design,’ said author Sophie Parry, of Trilux, who is Technical & Publications chair for the SLL.

Case studies were contributed by the late David Holmes and Simon Robinson, WSP Consulting.
