The 4-inch and 6-inch Recessed Adjustable Accent
The recessed adjustable accent is simply a downlight that can be aimed. Its versatility makes it one of the preferred workhorses of the lighting designer. This luminaire can be used like a theatrical lighting device to direct a defined piece of light onto any surface at which it is aimed. For many applications, the recessed adjustable luminaire can act as an accent, a wall-wash, or simply as a general downlight. They can be diffused with lens media to provide light that varies from dramatic and harsh to soft and flattering. These luminaires are particularly useful for “painting” pieces of light onto the specific objects and surfaces that we have identified on our light maps (see ch.17). Some simple project spaces can be lighted almost entirely with recessed adjustable luminaires. It is well worth specifying an adjustable luminaire that has the aiming mechanism recessed above the ceiling plane, rather than the all-too common “eyeball.” Some well-known manufacturers of adjustable accents include Erco, Zumtobel, and RSA, as well as those brands mentioned in the downlight family.
