A flush-mounted outdoor light works well attached to the ceiling of a porch or covered entry. They can also be used for a covered patio or deck area. The light is hardwired electrically to the ceiling and operated by a wall switch. It provides good ambient downward light to flood the local area, especially useful above a doorway or entrance. Being close to the ceiling/roof they allow amply head-room for people coming in and out. You may need more than one for a larger porch or wraparound deck.
The Arts and Crafts movement gave rise to the popularity of Craftsman design, in addition to Mission revival and the Prairie architecture of Frank Lloyd Wright. Mission Style Lighting is defined by the use of art glass with geometric shapes, solid materials, natural woods, and understated design elements that radiate substance and tranquility.
For outdoor use, ceiling lights should be mounted underneath the overhang of a porch or covered deck. They could also potentially be installed in a garage.
A ceiling-mounted outdoor light fixture will shine its light downward and outward over the local area. At night this light may well spread out over a fairly large area, centered on the porch. But it may not reach to the further reaches of a yard without additional lights. You may want to pair it with some wall/garage lights.
An electrician or person with electrical installation knowledge will need to permanently wire the ceiling light into the building's electrical supply.
