Task lighting is employed to illuminate an area where a specific task takes place. Task lighting ensures ample, focused light to support visual performance. It's a fundamental component of a layered lighting design in which lighting is composed of ambient, task and accent layers. Task lighting may come from furniture or ceiling mounted luminaires such as pendants, troffers, downlights, track lights, and under cabinet lights, or can be provided by portable floor and desk lamps. Task lighting should be provided without distracting glare and shadows. Task lighting should also be free of flicker and render colors of various objects accurately.
