Lighting products provide illumination and ambiance by emitting, managing, and regulating light. Lamps are lighting devices that produce light in various shapes, sizes, and styles. Used with lighting fixtures, lamps illuminate indoor and outdoor spaces. Indoor fixtures offer general, task, or accent lighting. Outdoor fixtures are designed to withstand weather. Ballasts and drivers give fluorescent and HID lamps the proper voltage and current. Controls like dimmers, sensors, and timers regulate light levels. Exit and emergency systems guide people out of buildings during emergencies or power losses. Hazardous location lighting works safely where flammable materials are present.
