Lighting fixtures are electrical devices that house and power light bulbs to produce light. Sometimes called luminaires, they mount to a ceiling or wall to spread light to the surrounding area. Light fixtures are designed and sized to suit specific applications and to accept specific light bulbs. Fixtures used for indoor lighting range from under cabinet fixtures for shining light onto countertops to bay lights for delivering large amounts of light from a high ceiling to the floor. Outdoor fixtures include roadway lights for lighting streets or parking lots and landscape lights for accent lighting of building exteriors and gardens.

Lighting products supply light for emergency situations, general work environments, and specific job tasks. They include industrial lighting fixtures, shop lights, garage lighting, LED lighting fixtures, emergency lighting, light bulbs, and more. Job site and task lightings, such as temporary lighting or medical lighting, or machine tool lights, provide hands-free lighting for general job-site work or specific tasks. Lamps and light bulbs can be used in permanent light fixtures while portable lamps and flashlights are handheld tools used for temporary or general lighting. Ballasts, lighting controls, and replacement parts are used to maintain and operate a lighting system.
