B. Functional (cont)
Different forms of functional lighting to suit all requirements.
1. General or ambient lighting This provides a uniform spread of light over a large area. This is usually achieved through a variety of ceiling light fittings. Examples are in open plan offices, corridors and sports halls. There are guidelines for recommended lighting levels in different spaces - usually measured in Lux at floor level unless stated.
2. Task lighting Task lighting sheds light on a task at hand; food preparation, laboratory work or reading for which a brighter light is required for a smaller point of focus. If there is enough general light a task light is not required.
As a word of warning, Halogen bulbs can get very hot so a compact fluorescent bulb or LED bulb should be considered as these are cooler to the touch. 3. Accent lighting Accent light is often used to highlight features such as a paintings in a gallery or a museumdisplay.
