The Arc Lamp is the first commercially successful form of electric lamp. It changed the world of lighting by setting the trend on carbon electric lights.
Humphry Davy
No, Xenon arc lamps usually contain Mercury, and other dangerous chemicals and gases, usually under extremely high pressures too, even when the lamp is cold.
The 'arc' in arc welding is not an acronym but in turn is a reference to the electric arc that is being generated during the welding process.
An arc-second is equivalent to one sixtieth (1/60) of one arc-minute. An arc-minute is equivalent to one sixtieth (1/60) of one degree.
0.01 arc second is one hundredth of an arc-second.An arc-second is one sixtieth of an arc-minute. (There are about 30 arc-seconds across the visible diameter of the Sun or Moon).An arc-minute is one sixtieth of a degree.A degree is one three hundred and sixtieth of a circle.So a hundredth of an arc-second is a good resolution for a fine telescope.If you have an image of the Moon where the moon is 3000 pixels wide (probably twice the width of your computer screen) then 0.01 arc-second is one pixel.
An arc lamp is a lamp that produces light by an electric arc. The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the early 1800s, was the first practical electric light.
An arc lamp is a general term for a class of lamps that uses an electric arc or voltage arc to create light. You've seen the bright light given off by electric arc welding, and the idea of the electric arc is the principle behind an arc lamp.
The function of any ballast in a lighting fixture is to raise the voltage high enough to strike an arc through the bulb or tube.
A combination of neon, argon, xenon, krypton, sodium, metal halide, and mercury. The common fluorescent lamp is a low pressure mercury arc lamp.

An arc floor lamp can not only make your room attractive, but it can help shed light on something that you are reading or something you are doing on your computer. This reduces eye strain.
Sir Humphrey Davy invented the electric carbon arc lamp in 1801. Goerges Claude invented the neon lamp in 1911.
