What is a discharge lamp used for?
A discharge lamp is a ‘Lamp that produces light by discharging an electric current through a gas (neon, argon, krypton) or a gas / metal vapour mixture (mercury, sodium).
What kind of light does an LED give off?
A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.

What are the types of discharge fluorescent lamp?
Discharge lamp types include low pressure mercury (fluorescent), induction, high pressure mercury vapour, mercury-blended, metal halide, low pressure sodium and high pressure sodium.
What gas is in a UV bulb?
UVC bulbs are filled with either Argon gas or a mixture of rare gases including Argon, Neon and/or other gases depending on the germicidal requirements for your application. They are constructed similarly to fluorescent lamps and operate the same with a similar discharge device.
