Most of the lighting schemes concentrated on illuminating individual rooms and providing good task lighting for the various activities carried out in them. However, lighting can also be used as a means of decorating rooms and highlighting their best features. Spotlights offer great flexibility here. They are available as single, double and triple spot units for wall or ceiling mounting, as individual spotlights that is designed to fit on a lighting track, or as recessed ‘eyeball’ ceiling fittings. The beam direction can be adjusted to ‘wash’ walls, curtains (drapes) or ceilings with light, which may be coloured instead of white; or to illuminate an individual area of the room such as a fireplace, an arch, anal cove, a display unit (cabinet) or some other feature.
Small spotlights, especially the recessed eyeball types, can be used to illuminate individual pictures or picture groups. Alternatively, a traditional picture light – a small strip light in a wall-mounted holder maybe set or below the picture.
Shelves or closed cabinets displaying china, glass or other objects can be arranged in several ways. Spotlighting is one, but this can look harsh. What often works better is either backlighting via small tungsten filament strip lights fined beneath the shelves or, where glass shelves are used, a lamp behind a frosted glass panel at the top or bottom of the unit.
The last area of lighting that needs to be considered is indoor security lighting. It is well known that intruders are deterred by good lighting outside the house and this also applies indoors. If a would-be intruder sees an indoor light, he or she can never be sure whether the house is occupied or nor, especially if the curtains are drawn. Even if the owners are out, an intruder will be less keen to break in and risk being seen from outside.
There are several types of programmable controls which can be used to switch on both fixed lighting and plug-in lights, either at preset times or are sternest. Some can then mimic human behaviour by turning lights on and off at random during the night.
