Lighting, now in its sixth edition, is the standard text on the principles and practice of lighting interiors and exteriors. The book introduces all the main principles of light and colour, along with the design of general lighting schemes. It complies with the CIBSE lighting code and guides, covers the main calculations that a lighting designer needs to do and includes worked examples. The book starts with the theory of light and how it is perceived by the eye. It looks at the units used and the subjective effect of colour. The characteristics of various types of lamp are described along with luminaires (the equipment that contains the lamps). The effects of daylight on light levels indoors are described before going on to look at the design of general lighting schemes. The book concludes with chapters looking at lighting for specific applications including roadway lighting, floodlighting, and the interior of specific building types.
