Task lighting

Recessed downlights, in particular the directional type, often serve double-duty as task lighting. Task lighting is a fundamental component of a layered lighting design, as it provides sufficient illuminance for users to perform visual tasks safety, efficiently and accurately. Task luminaires fall into two groups: localized task lights and overhead luminaires, Localized task lights include table lamps, floor lamps, undercabinet lights, and shelf lights. Overhead luminaires such as ceiling lights, pendants, troffers, track lights, and downlights, can also be used to illuminate a task. In commercial and hospitality applications where the architectural lighting design concept is embraced, recessed directional luminaires are the predominant choice to provide targeted illumination for accomplishing tasks. These luminaires provide architectural integration and reduce visual clutter that comes with the installation of localized task lights. In open plan spaces and buildings with tall or vaulted ceilings, task lighting is often provided by downlights because other overhead luminaires are very likely to compromise the architectural aesthetics and functionality of the space, while in such spaces table- or furniture-mounted task luminaires are simply not included in the design. The focused, localized beam of light delivered by directional downlights provides task visibility for a specific area, which helps define the spaces, consolidates the layered design, and eliminates the discomfort glare accompanying other overhead luminaires.
