The earliest practical electric lamp was incandescent lamp, but before the birth of incandescent lamp, an Englishman Humphrey David made an arc lamp with 2000 batteries and two carbon rods, but this kind of arc lamp was too bright, generated too much heat and was not durable, so it could not be used in ordinary places.
