Cove lighting
Cove lighting is a form of indirect lighting built into ledges, recesses, or valences in a ceiling or high on the walls of a room. It directs light up towards the ceiling and down adjacent walls.〔http://www.lrc.rpi.edu/resources/publications/lpbh/074Architectural.pdf〕 It may be used as primary lighting, or for aesthetic accent, especially to highlight decorative ceilings. Cove lighting is valued because it hides the fixtures, and because it provides a very even, warm light.
== Types of cove lights==
One method of installing cove lighting is by using T5 fluorescent tubes. T5 luminaires are an energy-efficient alternative to larger luminaires (such as T8 lamps) because they save on materials.〔http://www.lrc.rpi.edu/programs/nlpip/lightingAnswers/lat5/pc12.asp〕 An even better energy-efficient alternative is to use LED strips, mounted on an aluminium profiles for optimum heat dissipation, with prismatic covers. With a dimming controller (either analog 1..10V controls or digital, DALI based), the cove lighting can be dimmed. A wide range of LEDs are available, from warm white, daylight and even colour changing RGB modules.
