An English Tubelight is a common term for a fluorescent tube lamp in South Asia. It is a type of electric light that uses a gas-filled tube to produce visible light by fluorescence. Fluorescence is the process of emitting light when a substance is exposed to ultraviolet radiation. Fluorescent lights are more energy-efficient and last longer than incandescent bulbs, which use a heated filament to produce light.
In this article, we will explain what an English Tubelight is, how it works, and how to use it in your home or office. We will also compare it with other types of lighting and give you some tips on how to choose the best one for your needs.
How Does an English Tubelight Work?
An English Tubelight consists of a glass tube filled with a low-pressure mixture of mercury vapor and argon gas. The tube has electrodes at both ends that are connected to an electric current. When the current passes through the gas, it excites the mercury atoms and causes them to emit ultraviolet photons. These photons then hit the phosphor coating on the inside of the tube, which absorbs them and re-emits them as visible light of different colors depending on the composition of the phosphor.
The color temperature of an English Tubelight can range from warm white (2700K) to cool white (6500K), depending on the type of phosphor used. The color rendering index (CRI) of an English Tubelight measures how well it reproduces the colors of objects under its light. The higher the CRI, the more natural and accurate the colors appear. The CRI of an English Tubelight can vary from 50 to 90, depending on the quality and brand of the lamp.
How to Use an English Tubelight?
An English Tubelight can be used for various purposes, such as general lighting, task lighting, accent lighting, or decorative lighting. It can be installed in different fixtures, such as ceiling lights, wall lights, floor lamps, table lamps, or pendant lights. It can also be linked together to form long strips or arrays of lights.
To use an English Tubelight, you need a compatible ballast and starter. A ballast is a device that regulates the current and voltage in the lamp circuit. A starter is a device that provides a brief surge of current to ignite the gas in the tube. Some English Tubelights have an integrated ballast and starter, while others require separate ones. You also need a suitable socket and wiring to connect the lamp to the power source.
To install an English Tubelight, you need to follow these steps:
Turn off the power supply and remove any existing lamp from the fixture.
Attach the ballast and starter (if needed) to the fixture according to the manufacturers instructions.
Insert one end of the English Tubelight into one socket and twist it slightly until it locks into place.
Repeat with the other end of the lamp and the other socket.
Turn on the power supply and enjoy your new light.
How to Choose an English Tubelight?
When choosing an English Tubelight, you need to consider several factors, such as:
The size and shape of the lamp. English Tubelights come in various lengths, diameters, and shapes. You need to choose one that fits your fixture and space.
The color temperature and CRI of the lamp. You need to choose one that suits your preference and purpose. For example, warm white lights are more cozy and relaxing, while cool white lights are more bright and stimulating. High CRI lights are more suitable for tasks that require color accuracy, such as painting or sewing.
The wattage and lumens of the lamp. You need to choose one that provides enough light for your needs without wasting energy. Wattage measures how much power the lamp consumes, while lumens measure how much light it produces. The higher the lumens per watt ratio, the more efficient the lamp is.
The lifespan and warranty of the lamp. You need to choose one that lasts long and has a good warranty period. The average lifespan of an English Tubelight is 04f6b60f66
