Lighting businesses supply products and services for illuminating homes, workplaces and outdoor spaces. Retailers typically offer ceiling lights, wall lights, table and floor lamps, pendant fittings, spotlights, bulbs and replacement components. Products may include LED and traditional lamps, dimmable fittings, decorative lighting, task lighting and exterior lights. Staff may help customers choose fittings for a room, check compatibility with existing bulbs or controls, and advise on brightness, colour temperature and energy use. Some businesses also provide lighting design, supply and installation for domestic, commercial or industrial premises. Services can include planning light positions, fitting new luminaires, replacing existing fittings, installing controls such as dimmers or sensors, and maintaining or repairing lighting systems. Outdoor and specialist work may cover security lighting, garden illumination, emergency lighting or display lighting.
