Tubes & Bulbs

Tubelights and bulbs are two common types of electric lighting devices used in homes, offices, and other buildings.

A bulb, also known as an incandescent bulb, is a small glass bulb containing a filament made of tungsten wire. When an electric current is passed through the filament, it heats up and produces light. Bulbs are typically available in different wattage ratings and are commonly used for household lighting.

A tubelight, on the other hand, is a type of fluorescent lamp that consists of a long, narrow tube filled with a gas such as mercury vapor. The tube is coated with a fluorescent material that emits light when excited by ultraviolet radiation produced by the gas. A tubelight requires a ballast to regulate the electric current flowing through it. Tubelights are commonly used in offices, commercial buildings, and other large spaces.

In terms of energy efficiency, tubelights are generally more energy-efficient than bulbs, as they produce more light per watt of electricity consumed. However, bulbs are often preferred for their warm and cozy glow, which can create a more comfortable and relaxing atmosphere.
