High pressure sodium lights – High pressure sodium light is a specific type of light that creates a valued golden glow with only a fraction of the energy of other lights take. These lights has a number of uses, and the work due to the properties inherent in the sodium gas. Low pressure lights take several minutes to charge up and cool down before they can be turned on again, but high light react faster.
Sodium light functions in a very similar method for the fluorescent, mercury vapor, and metal halide light. The primary difference between sodium lights and fluorescent tubes is the absence of deposits in the high pressure sodium lights. Fluorescent light produce light by activating an internal coating on the bulb through the gas, while the sodium light energy actually sodium trapped gas inside the bulb to produce light.

Sodium light has a component inside the bulb, which allows an electric current to circulate through the lighting system. This stream is carefully controlled by a ballast that reduces tension and current cycles to the appropriate levels. When this current passes through the gas, it gives some of its energy to the high pressure sodium lights. The electrons of atoms increase in energy levels and the current cycle passes they fall back again, releasing their excess energy in the form of light photons.
