What Is Tubelight?

Are you curious to know what is tubelight? You have come to the right place as I am going to tell you everything about tubelight in a very simple explanation. Without further discussion let’s begin to know what is tubelight?

In the realm of lighting, the tubelight stands as an enduring symbol of illumination, providing a steady and efficient source of light in various settings. This blog aims to delve into the essence of the tubelight, uncovering its mechanics, historical significance, and enduring role in illuminating spaces across the globe.

What Is Tubelight?

  1. Mechanics of a Tubelight: A tubelight is a type of fluorescent lamp that operates through the excitation of mercury vapor within a sealed glass tube. Electricity passes through the tube, stimulating the mercury vapor, which then emits ultraviolet light.
  2. Phosphor Coating and Visible Light: The ultraviolet light interacts with a phosphor coating lining the interior of the tube, causing it to fluoresce and emit visible light. This process produces the soft, diffused glow associated with tubelights.

Historical Significance And Evolution

  1. Invention and Development: The tubelight’s development traces back to the early 20th century, with significant contributions from inventors such as Peter Cooper Hewitt and later innovations by General Electric and others.
  2. Efficiency and Popularity: Tubelights gained popularity due to their energy efficiency and prolonged lifespan compared to traditional incandescent bulbs, becoming a staple in residential, commercial, and industrial lighting.

Practical Applications And Variants

  1. Versatility in Applications: Tubelights find application in various settings, from illuminating homes, offices, and public spaces to specialized uses in photography, horticulture, and industrial environments.
  2. LED Tubelights: With advancements in lighting technology, LED (light-emitting diode) tubelights have emerged, offering improved energy efficiency, longer lifespans, and environmental benefits compared to traditional fluorescent tubelights.

Cultural And Symbolic Significance

  1. Metaphorical Symbolism: Beyond its practical utility, the tubelight carries metaphorical significance, often symbolizing ideas of illumination, enlightenment, or moments of clarity in literature, art, and popular culture.
  2. Cultural Impact: In various cultures, tubelights feature in rituals, festivals, or as iconic elements in cinematic settings, representing illumination, hope, or a guiding light in narratives.


The tubelight, with its efficient and reliable illumination, transcends mere functionality, embodying a symbol of light, innovation, and practicality. From its invention to modern iterations, the tubelight continues to play a pivotal role in illuminating our homes, workspaces, and diverse environments. Its metaphorical resonance and cultural significance further reinforce its enduring presence as more than a source of light, but as an emblem of illumination that brightens both physical spaces and metaphorical realms of thought and imagination.


What Is The Tubelight?

Tube light is a fluorescent lamp that consists of a cylindrical tube. Dissolution of low-pressure mercury vapor converts ultraviolet rays into visible rays using coated phosphor inside the tube light. The fluorescent coating on the tube enhances the conversion of an external source of light to visible light.

What Is A Light Tube Called?

The fluorescent tube, also referred to as the fluorescent strip or tube light, is a low-pressure mercury vapour gas-discharge tube that converts fluorescence into visible light.

What Makes Tubelight Glow?

A fluorescent lamp generates light from collisions in a hot gas (‘plasma’) of free accelerated electrons with atoms– typically mercury – in which electrons are bumped up to higher energy levels and then fall back while emitting at two UV emission lines (254 nm and 185 nm).

What Is Tube Light Wiring?

We need tube light, ballast, starter and fluorescent light holders to make wiring connection. The fluorescent tube has two filaments with four terminals the starter is connected between two filaments, the ballast is connected between main Ac supply and one filament in tube light.
