The world renowned Lighting Research & Technology journal will be celebrating its 50th anniversary in 2018. Whilst celebratory events are in the pipeline for 2018, the Society of Light and Lighting is delighted to announce that Christopher (Kit) Cuttle will be delivering a warm up lecture on 10 October 2017 at University College London. Kit Cuttle's lecture will be entitled A Fresh Approach to Interior Lighting Design: An Exitance-based Procedure. A novel lighting design procedure is proposed based on how lighting influences the appearance of indoor spaces and their contents. Exitance is the measure of the density of luminous flux (lm/m2) exiting, or emerging from, a surface, and provides an effective basis for relating the quantity and distribution of lighting to peoples’ assessments of its visual effects. The procedure guides users from identifying selected lighting design objectives relating to how peoples’ assessments of appearance are affected by lighting, to developing a specification for the direct flux distribution that will optimally achieve those objectives. Applications can range from basic to complex, and a downloadable interactive spreadsheet may be accessed to facilitate operation of the procedure. Kit Cuttle has had a long and varied career in lighting. He has worked on daylighting at Pilkington Bros in the UK, taught illuminating engineering and, more lately, lighting design at the University of Wellington, New Zealand, the Lighting Research Center in Troy, NY, and the University of Auckland, New Zealand, as well as writing several books on the subject. Throughout his career he has been known for his willingness to push the boundaries of lighting metrics. This process is evident in his current attempts to convert people away from photometry to perception-based metrics.
