Also (rare) figurative.The light was first produced either by causing an electric arc to form between two electrodes, or by passing an electric current through a wire so as to heat it to incandescence; it was the latter method that gave rise to widespread electric lighting following the development of the light bulb in the late 19th cent. Later other sources of electric light were developed, such as fluorescent lamps and light-emitting diodes.Although Humphry Davy ( Jrnls. Royal Inst. (1802) 1 188) observed the ‘dazzling brightness’ of a spark between brass electrodes, and the ‘vivid whiteness’ when the electrodes were of charcoal, this was merely incidental to his researches into electricity.Also in 1802, V. V. Popov in Russia is reported to have observed a continuous arc discharge and to have suggested its use for illumination (see A. Anders in IEEE Trans. Plasma Sci. (2003) 31 1064).
