Background on Incandescent Bulbs 

Incandescent bulbs come in one of the oldest lighting techniques. The first inventor of the incandescent bulb was ”Thomas Edison” in the 1800s. These bulbs work on one of the oldest methods of lighting which is the incandescence phenomenon which means light emission can be caused by heating filament. These have been used widely with slight modifications ever since.

Explanation of Incandescent Bulb Technology

Incandescent lighting is known as the original form of lighting. Incandescence term is usually used for the light produced by heat radiations. Incandescent light bulbs are glass or metal devices that contain an electric wire tungsten filament that produces lumination when heated by a passing current. The current is supplied to the filament through terminal wires embedded in a glass case which is attached through a metal base. The current used is high in resistance so it causes the bulb’s filament to heat up and glow with light. These bulbs contain a glass mount attached to the metal base, which is then attached to the fixture for current flow. The glass mount contains metal filament it that produces lumination to protect this filament from damage and evaporation. The outer glass case contains inert gasses or a vacuum.

Advantages and Disadvantages of Incandescent Bulbs

It is a universal truth whenever, there is any invention that will have many advantages along with disadvantages, such is the case with incandescent bulbs as they were widely used in the past for lumination purposes. They are one of the forms of lighting that were used 100 years ago. Incandescent bulbs work on heating techniques of filament through current flow.

In the past, these bulbs were widely used with slight modification with the passage of time. In that era, they were cheaper and economical for use in household and commercial areas. The incandescent bulb is a fairly simple device manufactured in a wide range of design sizes and voltage output ratings. They don’t require any regulating equipment and have low manufacturing costs, so incandescent bulbs are pocket-friendly to be purchased.

Along with that, there are many other advantages of incandescent bulbs, such as

  • They provide you with warm and natural light that makes your place’s ambiance more authentic and vibrant as they produce light that is very close to sunlight.
  • They are also heat-producing so can be safely used in bathrooms, incubators, lava lamps, heating lamps, or in food warming lamps.
  • They are also cheaper in price due to low-cost manufacturing 

While incandescent light bulbs’ design has been improved over time still they have many drawbacks to be used nowadays.

They are less efficient than other lighting sources and they consume more energy and give less output. Less than 5% of the overall energy consumed by incandescent bulbs is converted into visible light and the rest of that is lost as heat which is a major drawback. More power voltage is required to run an incandescent bulb as compared to an LED bulb and in return, it gives less lumination than an LED bulb.

Along with this, there are many other disadvantages of incandescent bulbs.

  • They have a shorter lifespan and they will provide service of just 750-2000 hours. And require replacement every 3 to 4 months which causes inconvenience.
  • They heat up so much that there is a chance of damage to electric fixtures due to overheating and can even pose a fire which is an alarming condition.
  • They are highly  fragile and can be damaged with little shock as compared to LED bulbs
  • The use of incandescent bulbs is not a pocket-friendly choice as they are meant to be replaced after some time which makes them expensive to use.
  • They have a major drawback of getting expired without any indication of dimmer light which may leave you in darkness when you are in the middle of work.
  • Emitted light from incandescent bulbs is not perfectly white so it may not work for many places where bright light is required.
