Yablochkov's electric arc lamp 
(Yablochkov's candle) is made of two coal rods divided with a layer of 
plaster that evaporates as an effect of an electric arc discharge. 
The coal rods are connected to a source of an electric currant 
that initiates an electric arc between the rods. Yablochkov's 
candle was invented in 1876. Following mechanisms to 
regulate the brightness of the light were invented: a suspended 
electric lamp with automatic control, a desktop electric arc lamp 
of Vladimir Chikolev's system, and coal rod arc lamp control 
system.
