10 facts to know about Mercury lamp spectrum

Mercury lamp spectrum is a high power discharge lamp. It utilizes an arc through vaporized mercury in a high-pressure tube to create splendid spectrum of light specifically from its own particular arc.

It’s not similar to fluorescents which use the mercury vapor arc to create a weaker light that primarily produces UV light to energize the phosphors. The mercury lamp as it is known has been a workhorse for society by lighting lanes, processing plants, and extensive zones for more than 100 years.


The first mercury lamp spectrum was in a lower pressure tube. One would tilt the lamp, and electrical touches on each side of the lamp would send power through a liquid mercury which lit the lamp.

After that, the lamp would warm fast, and mercury will be turned into steam. The light would increase as the arc grew bigger in the tube.


Mercury lamp spectrum begins with a little arc between the starting electrode and the principle electrode. This arc experiences argon gas which effortlessly strikes, even in icy weather.

This little arc warms the tube, and more than a few minutes the tube gets hot enough to vaporize the strong mercury stuck to the sides. The mercury evaporated creates an intense spectrum light between the two first electrodes.
