Ever since the invention of the incandescent light bulb, manufacturers have worked to develop an increasingly varied choice of light sources - from miniature filament bulbs to speciality fluorescent sign lamps. Recent technological advances have brought about smart lighting control systems and the prioritisation of lighting efficiency, economy and aesthetics, with cost-effective light-emitting diodes and a choice of lighting colour temperatures. LED lamps in sealed units are popular in shop windows and corridor lighting systems, while lighting strips can be used to illuminate display cabinets or to provide diffuse, ambient wall wash lighting. The choice of light sources and styles for industrial and business applications is immense, whether for retail, offices or hotels. In commercial or production areas, fluorescent lamps with magnetic starters and electronic ballast units are reasonably energy-efficient - though long-lasting LED bay lighting luminaries offer even lower consumption. Halogen lamps vary from standard mains voltage bulb units with reflectors to low voltage lighting systems featuring mains to DC transformers. Indicator lamps include bayonet cap bulbs, glow lamps and LED signal lamps in red, green and blue, as well as laser pointers for presentations. Finally, the category of light sources also covers lamp holders, sockets and replacement automotive bulbs for car headlamps, sidelights and dual filament stop/taillights.
