LIGHTING EQUIPMENT LISTING AND LABELING Most States Ruling that all electrical equipment, including light fixtures, devices, and appliances shall be LISTED AND LABELED by a nationally recognized testing laboratory (i.e. Underwriter's Laboratories, Canadian Standards Association, etc.) as having been tested and found suitable for a specific purpose. All electrical equipment shall be installed and used in accordance with the listing requirements and manufacturer's instructions. Most State Energy Codes require that all penetrations through an air barrier be sealed so that the interior air barrier is maintained. Sealing applies to all penetrations including the service entrance, conduit, cables, panels, recessed luminaires, electrical boxes, and fan housings. NATIONAL ELECTRICAL CODESNEC 210-70 At least one wall switch controlled lighting outlet shall be installed in every interior stairway, with a switch at each floor level to control the lighting outlet when the difference between floor levels is six steps or more.

NEC 410.2 Lighting Fixtures closets Closet storage space is the volume bounded by the sides and back closet walls and planes extending from the closet floor vertically to a height of 6 feet? or the highest clothes-hanging rod and parallel to the walls at a horizontal distance of 24 inches from the sides and back of the closet walls respectively, and continuing vertically to the closet ceiling parallel to the walls at a horizontal distance of 12 inch or the shelf width, whichever is greater. NEC 410-8 Lighting fixtures installed in a clothes closet shall have the following clearances from the defined storage area (see the definition below): . 12 inches for surface incandescent fixtures . 6 inches for recessed incandescent fixtures . 6 inches for fluorescent fixtures NEC NEC 410-8 Storage space, as applied to an electrical installation in a closet, is defined in the National Electrical Code as a volume bounded by the sides and back closet walls and planes extending from the closet floor vertically to a height of 6 feet (1.83m) or the highest clothes-hanging rod and parallel to the walls at a horizontal distance of 24 inches (610 mm) from the sides and back of the closet walls respectively, and continuing vertically to the closet ceiling parallel to the walls at a horizontal distance of 12 inches (305mm) or the width of the shelf, whichever is greater. NEC 410-8 Incandescent fixtures with open or partially enclosed lamps and pendant fixtures or lamp holders are not permitted in clothes closets. NEC 410.8 Wiring Methods closet lighting fixtures Luminaires (lighting fixtures) installed in clothes closets shall have the following minimum clearances from the defined storage area: 300 mm - 12 inches for surface incandescent fixtures, 150 mm 6inches for recessed incandescent fixtures , 150 mm 6 inches for fluorescent fixtures. NEC 410-8 Lighting fixtures installed in a clothes closet shall have the following clearances from the defined storage area (see the definition below): 12 inches for surface incandescent fixtures, 6 inches for recessed incandescent fixtures, 6 inches for fluorescent fixtures. NEC 410-8 Storage space, as applied to an electrical installation in a closet, is defined in the National Electrical Code as a volume bounded by the sides and back closet walls and planes extending from the closet floor vertically to a height of 6 feet (1.83m) or the highest clothes-hanging rod and parallel to the walls at a horizontal distance of 24 inches (610 mm) from the sides and back of the closet walls respectively, and continuing vertically to the closet ceiling parallel to the walls at a horizontal distance of 12 inches (305mm) or the width of the shelf, whichever is greater.

Surface mounted fluorescent or LED luminaires listed for installation in storage space shall be permitted. NEC 410-66 Recessed lighting fixtures installed in insulated ceilings or installed within one half inch of combustible material shall be labeled as Type IC (insulation contact). In addition, your state Energy Code requires recessed lighting fixtures in insulated ceilings to be sealed to prevent leakage of airborne moisture.
