An electronic bulb is a small and simple light source that uses a wire filament to glow on the application of electricity. The structure of incandescent light bulbs is shown in the figure below. The filament, which is a coiled thin wire, is made of tungsten.

An incandescent bulb works on the principle of incandescence, a general term meaning light produced by heat. In an incandescent type of bulb, an electric current is passed through a thin metal filament, heating the filament until it glows and produces light.

tungsten filament An incandescent bulb typically consists of a glass enclosure containing a tungsten filament. An electric current passes through the filament, heating it to a temperature that produces light.

The three metrics you should know that relate to light bulbs are lumens, wattage, and light color. Lumens are the measure of brightness, wattage is the amount of power it takes to light the bulb, and light color (measured on the Kelvin scale) determines whether the light takes on a yellowish or whitish hue.

There are three basic kinds of light bulbs on the market: incandescent, halogen, and CFL (compact fluorescent light). Mark Candido, co-owner of The Accessory Store in Stamford, Connecticut, explains the differences in terms of aesthetics and energy usage.

There are four popular types of lightbulbs: incandescent, compact fluorescent (CFL), halogen, and light-emitting diode (LED). Light-Emitting Diode (LED): One of the most energy-efficient lightbulb types, it gives off no heat, contains no mercury, and emits a bright light.

A series of flames evaporates moisture and bakes off any impurities. As the two production lines merge a bulb goes over each mount.

The light bulb was invented for the purpose of giving off light. It was designed to produce a more consistent, longer-lasting, higher quality light than that produced by oil or gas lamps (which were the standard means of lighting before electric light).

5 facts about Light Bulbs you probably didn't know

• The worlds longest lasting light bulb has been used for over a century.
• The process of inventing the lightbulb did not start with Edison.
• Incandescent lightbulbs can affect concentration.
• The human brain runs on a fifth of the wattage of a standard lightbulb.

Your Best Light Bulb Choice General-purpose LED bulbs fit standard light sockets and are the most energy-efficient option. LED bulbs have a lower wattage than incandescent bulbs - meaning they use less energy - but still have the same light output. LED bulbs can last more than 20 years and don't contain mercury.

Today, the longest-lasting light bulbs are primarily light-emitting diode (LED) bulbs. General-purpose LED bulbs fit standard light sockets and are the most energy-efficient option. LED bulbs have a lower wattage than incandescent bulbs - meaning they use less energy - but still have the same light output.

There are three basic kinds of light bulbs on the market: incandescent, halogen, and CFL (compact fluorescent light).

There are four main types of lighting – ambient, task, accent, and decorative.

Since most consumers look to purchase a cheaper light bulb, most light bulbs are manufactured over seas in China where it is more cost effective for companies to do so.

The LED manufacturing process First, the semiconductor material is grown in a high-pressure, high-temperature chamber, where elements (gallium, arsenic, phosphor) are purified, mixed, and liquified into a concentrated solution. Once combined, a rod is placed into the solution and slowly pulled out.
