Recessed Lighting Small circular lights that are installed in the ceiling Direct lighting downward or angle it toward an area or object

Cornice Mounted at the intersection of a ceiling and a wall, washing the wall in light to provide a reflected light to the room

Task Lighting Helps people perform specific tasks Bright but not harsh, free from distracting glare Soffit Lights- effective task lights, the underside of the soffit is sometimes covered with a diffusing panel
