ABSTRACT

Lighting design is the process of developing lighting that enables the safe, productive and enjoyable use of buildings and spaces. Placing light on walls, considered best practice in contemporary lighting design, can produce two significant benefits. As ambient lighting is usually diffuse and uniform, it can be bland; for visual interest, accent or other lighting techniques can be used to create focal points or other interest. As a result, grazing is typically used as accent lighting to beautify strongly textured surfaces such as natural stone and brick as well as artwork such as carvings. Task/ambient illumination is a lighting design approach that combines a low-level direct/indirect general lighting layer providing ambient illumination and a more intensive task lighting layer providing sufficient light levels to complete critical visual tasks. The challenge is making the capital investment in dimmable ballasts worthwhile via infrequent reductions in load, particularly if daily load shedding is off the table.
