This LG14 'Control of electric lighting' is the first edition of a wholly new SLL Lighting Guide. 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. Luminaire and controls technology is moving quickly and some forms of emerging controls technology have yet to prove themselves and become commonplace in the built environment. For this reason LG14 acknowledges the existence of these new technologies and future editions will incorporate design considerations as these technologies become proven and commonplace. As other SLL Lighting Guides, the SLL Code for Lighting and the SLL Lighting Handbook are revised, the section(s) on controls contained within these other publications will be revised to align with LG14.
