Fluorescent Lamp

Fluorescent lamps are a type of electric lamp that falls under the supply class Electric Lamps in the supply group Lighting Fixtures And Lamps. These lamps are commonly used for general lighting purposes in various settings such as homes, offices, schools, and commercial buildings.

Fluorescent lamps work by passing an electric current through a tube filled with low-pressure mercury vapor and a phosphor coating on the inside of the tube. When the electric current flows, it excites the mercury vapor, which then emits ultraviolet (UV) light. The phosphor coating on the tube absorbs the UV light and re-emits it as visible light.

One of the main advantages of fluorescent lamps is their energy efficiency. They consume significantly less energy compared to traditional incandescent lamps, making them a popular choice for lighting applications where energy savings are important. Fluorescent lamps also have a longer lifespan, typically lasting up to 10,000 hours or more.

Fluorescent lamps come in various shapes and sizes, including linear tubes, compact fluorescent lamps (CFLs), and circular tubes. They are available in different color temperatures, ranging from warm white to cool white, allowing users to choose the desired lighting ambiance.

It's worth noting that with the advancement of LED technology, LED lamps have become increasingly popular as a more energy-efficient alternative to fluorescent lamps. However, fluorescent lamps still have their place in many lighting applications due to their affordability and widespread availability.

Overall, fluorescent lamps are a type of electric lamp that provides energy-efficient and long-lasting lighting solutions for a wide range of settings.
