Which kind of light bulb is more efficient? Which kind of light bulb produces more light?

Here we have a complete light bulb buying guide which helps you to understand what is your requirement and what kind of light bulb is more suitable for you. There are different factors you need to consider before buying a light bulb. In this light bulb buying guide, we will tell you about different types and their advantages and disadvantages in detail. By knowing these light bulb buying details, you won’t need to worry about buying a light bulb as you can choose the best type which meets your requirements.

Different types of light bulbs

The first thing you need to know before buying a light bulb is types of light bulbs and their advantages and disadvantages. By knowing different types of light bulbs, you can easily which one is the best for you. Each one of these types of light bulbs has their own characteristics and benefits.

There are four main types of light bulbs: Incandescent, Halogen, CFL, and LED. We are going to tell you about each type advantages and disadvantages along with explaining.

Incandescent bulbs

As the name indicates. Incandescent light bulbs are working by a function called incandescence. This means this type of light bulb produces light by heating a filament and that’s why incandescent bulbs are also known as filament light bulbs. This type of light bulb has been in use for a long time, maybe more than 100 years.

It’s been told that Thomas Edison was the inventor of this type of the light bulb, but some people believe that the tungsten bulb was invented before Thomas Edison. The Incandescent light bulb is made from a glass enclosure and there is a filament in it. The electric current heats up the filament by passing through it and this will produce heat and light.

Advantages of incandescent bulbs

Incandescent light bulbs come in a wide range of shapes and models and you can choose among them based on your house or workplace design. The most important thing about filament light bulbs is the low manufacturing cost and their adaptability to different types of electric current and it works on both alternating and direct current. It also works with common control devices such as a timer and dimmer.

Disadvantages of incandescent bulbs

The most important disadvantage of the tungsten bulb is energy efficiency issue. Incandescent bulbs consume high amounts of energy to produce light and this makes them not so nature-friendly and based on some new rules in most of the countries around the world manufacturers are not allowed to produce this type of light bulb anymore.

Halogen bulbs

Halogen light bulbs are a type of incandescent bulb with one difference, they get filled with halogen gas in the glass enclosure and Halogen light is warmer and you can choose among different halogen bulb types.

The gas inside the halogen lamp increases the amount of light and energy as it can get hotter and halogen flood light becomes more and warmer. You can get a lot of light from small halogen bulbs. The gas inside halogen lamp bulb reacts chemically with tungsten and that makes tungsten halogen lamp become more durable as it won’t be like incandescent bulbs.

Advantages of halogen bulbs

You can choose among different halogen light bulbs types and halogen globes. Halogen light bulbs are more durable and more energy efficient. They use less energy while producing more light. The halogen gas inside the enclosure returns tungsten to the filament and that makes it more durable. Halogen bulbs are used in headlights of the cars as they produce more light and they are more durable.

Disadvantages of halogen bulbs

Halogen light bulbs are costlier in comparison with incandescent light bulbs, especially linear halogen bulb and another problem of this type of light bulb is that they become very hot and you can’t touch them with hand. Pressurized gas inside the lamp also makes it a little more dangerous in case it shatters and extra precaution is needed.

CFL bulbs

CFL light bulbs or compact fluorescent light bulbs are known with different names such as compact fluorescent bulbs, CFL tube or fluorescent tubes. These lamps come in different shapes and sizes and are quite an energy efficient in comparison with other light bulbs, especially the incandescent bulb.

Fluorescent bulbs use one-third to one-fifth energy to produce the same amount of light. Fluorescent light bulbs are up to fifteen times more durable than incandescent bulbs but you have to know that you must pay up to five times more for fluorescent tube light. Although you have to pay more for buying a CFL lamp we can assure you having a fluorescent lamp will reduce your lighting costs up to times.

They can come in various shapes and sizes and you can even buy CFL candelabra bulbs to have more beautiful CFL bulb. You can use them almost anywhere you want and they are very energy efficient.

Disadvantages of CFL bulbs

It’s better to not use them with dimmer or timer and if you want to change the light intensity, it’s better to buy dimmable CFL. They are costlier and you need to pay much more than regular bulbs for them, but after a short time, you can save much more than you paid as they use less energy in comparison with other bulbs.

LED bulbs

LED lights or LED bulb, is producing light through the light emitting diode and is one of the best light bulbs when it comes to energy efficiency. The LED light is clear and everyone can tell the difference between LED lighting and other types of lamps.

Light bulb efficiency

Before explaining light bulb efficiency, you have to be familiar with some words and terminology in this section. There are some words used about light bulb efficiencies like lumens and watts. Lumens means the amount of light produced by the bulb and watts means the amount of energy that light bulb consumes.

Light bulb efficiency is directly related to these two words. An efficient light bulb converts more amount of energy it consumes to light and generates less heat. Among common types of light bulbs, incandescent, halogen, LED, and CFL, the most efficient one is LED and the worst one is incandescent.

Light bulb efficiency has a great importance as energy consumption is one of the biggest issues of people in the world. Although you have to pay more for buying a more efficient light bulb, you will save a lot of energy and money while using these types of bulbs. Light bulb efficiency is directly proportional to the technology used in the production of the lamp.

More efficient light bulbs convert most of the energy they consume into a light and they generate less heat, and that’s why when you touch LED or CFL light bulbs they are much cooler than incandescent light bulbs.

Incandescent bulb efficiency

When it comes to efficiency, incandescent light bulbs are the worst among different types of light bulbs. Incandescent bulbs are much cheaper than other types of light bulb as their manufacturing costs less in comparison with other types but instead, they consume high amounts of energy.

The light they produce is much less in comparison with the amount of energy they consume. This type of lamp generates a high amount of heat while efficient light bulb should convert all the energy it consumes into light and amount of heat must be negligible. We can say that the efficiency of incandescent light bulbs is about 10 percent.

Halogen bulb efficiency

Halogen light bulbs are more efficient than incandescent light bulbs, but they are not as efficient as CFL lamps. Also, Halogen light bulbs convert more amount of energy they consume into the light and they generate less heat in comparison with incandescent light bulbs, but still, there is a long distance between Halogen and CFL light bulbs when it comes to efficiency. We can say that halogen light bulbs are between 30 to 50 percent efficient.

CFL bulb efficiency

Compact fluorescent light is more efficient than halogen light bulbs and they consume less energy to produce the same amount of light. But still CFL light bulbs are less efficient than LED light bulbs and they require more amount of energy in comparison with them.

Of course, you have to pay more for buying a compact fluorescent bulb, but instead, you will save a lot of money as they consume much less energy in comparison to incandescent and halogen light bulbs. We can measure the efficiency of compact fluorescent efficiency as 68 to 80 percent.

LED light bulb efficiency

LED light bulb is the most efficient as it converts 90 to 95 percent of the energy it consumes into the light. As it generates less heat, you can easily touch this type of light bulb with a naked hand and this shows how efficient LED light bulbs are. It’s right that you have to pay more to buy LED light bulb but in future, you have to pay much less for your electricity bill. They also have a longer lifespan and are more durable than other types of light bulb.

In this buying guide, we tried to explain light bulbs from every aspect and point of view. by using this light bulb buying guide, you can compare different types of light bulbs and choose the best one which is most suitable for you. It’s always better to buy light bulbs from reliable suppliers like Dragon Mart Shop Dubai which is the best place for buying everything related to house construction and decoration.
