Lighting . Acetylene lighting was one of AB Gasaccumulator’s first products at the start in 1904. Lighting in meeting halls and railway carriages, lamps for vehicles and military use were major products before 1910. During the first world war a major upswing for acetylene lighting occurred in many countries cut off from petroleum supplies. The transfer from acetylene to electricity as a source of light led to the re-design of AGA’s lamps for various civil and military applications at the end of the 1920s. But gas lamps were also to prove a valuable reserve during the second world war, when electric power stations were destroyed or where easy-to-transport lamps were required. The early AGA manufactured a wide range of lamps: for acetylene/oxygen or electric power, for civil or military use, signal lamps, hand lamps, torches, etc.
