An arc lamp or arc light is a lamp that produces light by an electric arc (also called a voltaic arc). The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the first decade of the 1800s, was the first practical electric light .

The arc then continues to burn, gradually consuming the carbon electrodes and the intervening plaster, which melts at the same pace. The first candles were powered by a Gramme machine . The drawback of using direct current was that one of the rods would burn at twice the rate of the other.
Stanley lit 23 businesses along a 4000 feet length of main street stepping a 500 AC volt current at the street down to 100 volts to power incandescent lamps at each location. [8] 1893 GE introduces first commercial fully enclosed carbon arc lamp. Sealed in glass globes, it lasts 100h and therefore 10 times longer than hitherto carbon arc lamps ...
In the late 1960s German television producers requested lamp developer OSRAM to create a safer and cleaner replacement for carbon arc lighting used by the film industry. Osram developed and began producing HMI lamps at their request. [2] Philips produced a variation on the HMI, a single-ended version called MSR (medium source rare-earth). It ...
ATS officers-in-training crew a 90 cm searchlight in Western Command, 1944. A searchlight (or spotlight) is an apparatus that combines an extremely bright source (traditionally a carbon arc lamp) with a mirrored parabolic reflector to project a powerful beam of light of approximately parallel rays in a particular direction.
