Abstract
A luminaire includes a housing, a luminous zone coupled with the housing, and one or more transition zones coupled with the housing and disposed adjacent to the luminous zone. The luminous zone provides a first light to an illuminated area, and the one or more transition zones provide a second light to the illuminated area. The first light is harsher than the second light. A method of illuminating an area includes providing a first light to the area from a luminous zone of a luminaire and providing a second light to the area from one or more transition zones disposed adjacent to the luminous zone within the luminaire. The first light is a harsher light than the second light.
