What is Fluorescent Light?

Fluorescent lighting is a popular choice for many homes and businesses. Known for its energy efficiency and long lifespan, it offers bright, consistent illumination. These lights work by passing an electric current through a tube filled with mercury vapor, which then emits ultraviolet light.

This light is then converted into visible light by the phosphor coating on the tube. With its environmental benefits and cost-effective qualities, fluorescent lighting is a top choice for many lighting needs.

How Does Fluorescent Light Work?

Fluorescent light bulbs consist of several key components that work together to produce illumination. The main parts include the glass tube, the electrodes, the mercury vapor, and the phosphor coating.

When the electrical current is applied, it excites the electrons within the electrodes, causing them to emit electrons into the tube. These electrons collide with the mercury vapor, causing it to release UV light. The UV light then interacts with the phosphor coating, stimulating it to emit visible light.

The color of the light emitted depends on the composition of the phosphor coating.

Fluorescent light bulbs also contain a ballast, which regulates the electrical current flowing through the bulb. Ballasts are necessary to ensure the correct amount of energy is supplied to the bulb and to prevent flickering and premature failure.
