[1] It may be used as primary lighting, or for aesthetic accent, especially to highlight decorative ceilings.
Cove lighting is usually installed with LED strips, which have energy-efficiency benefits.
They are mounted on an aluminium profile for optimum heat dissipation, with prismatic covers.
A wide range of LEDs are available, from warm white, daylight and even ones that can change colour.
Luminaire strips should overlap the tubes to reduce the shadow effect at the lamp ends.
