LED Light Bulb: The basics, Pros and Cons And Cost

An LED light bulb is a ‘solid-state technology’ (SSL) and works in a different way to an incandescent bulb (the usual pear shaped bulb we have had for many years).

These old-fashioned bulbs emit light through a vacuum.

An LED bulb emits light from a piece of ‘solid material’ which in the case of a traditional LED this is a semi conductor.

Put simply, an LED bulb produces light when electrons move about within its semiconductor structure.

What has been a problem with LED bulbs is that a lot of light got trapped within the structure of the bulb and so LEDs were traditionally dimmer that the incandescent light bulb; most people want a fair level of brightness from their light fittings.

However, advances in technology means that LEDs have brightened with most LED bulbs emitting light equivalent to an incandescent 60w bulb; their use around the home is now far more viable.

The advantages of LED light bulbs

There are many benefits to using LED bulbs around the home and office, or anywhere that bright electrical light is required.

 1.They use far less energy

In this day and age where energy prices are increasing month on month, efficient energy use around the home and workplace is on everyone’s mind.

These LED bulbs are far more efficient – around 85% more efficient that the traditional incandescent bulb.

LEDs do not leak energy in the form of heat.

A single light fixture with an incandescent 60w bulb would use 525 kWh of electricity annually; using a LED bulb in the same way is estimated to use as little as 65 kWh per year, a massive saving.


Imagine not changing a light bulb for 20 years!

It’s estimated that LEDs last for around 20 years and are far more stable than the traditional incandescent bulbs.

The traditional light bulb lasts for around 750 hours with LED bulbs lasting around 30,000 hours (some LED bulb manufacturers have estimated their bulbs last 50,000 hours).


Things can get a little muddled here.

The traditional light bulb can cost as little as 60p but with the incandescent light bulb only lasting a relatively short period of time compared to the LED bulb, it would seem that spending 10 times as much on an LED bulb is far more cost effective, considering you might not need to buy another one for a number of years.

 4.Light colour

The early examples of LED bulbs had a bluish tinge to the light colour that they emitted, but with technology moving as fast as it does, the most modern LED bulbs now emit a soft, white light.

Are there any disadvantages?

Technology is a great thing that moves so fast, it can be hard to keep up.

What was sparkling new and top of the range today can be a sorry second the next day.

LEDs bulbs and technology is a fast moving technology with some famous brand names putting their money and resources into LED technology as opposed to other technologies. 

It would seem that the future for LED technology is looking good.

This will hopefully mean that prices within the sector will decrease, making the LED bulbs open to more people.

However a few issues remain:

  • Bulb design has meant that some light is still lost within the casing. Some manufacturers have attempted to solve this by making incredibly small holes in the casing but, this adds to the price as more technology and time is required to do this.
  • Supply issues can also push up the price but various scientists are now looking at new, exciting semi conductor materials. These materials are cheaper and, if they can be mass produced and used in the LED bulb design then this will help with the pricing. There is also a possibility that these new semi conductor materials will make the LED bulbs even more efficient, with some research from America suggesting they could last as long as 100,000 hours.

LED technology is an exciting place, with some many changes happening they are almost daily occurrences.

The current advantages of LED technology far outweigh any disadvantages.

It is a technology that everyone should, at some point, invest in.

LED Bulbs Keep Energy Emissions And Costs Down

LED bulbs can have a huge influence on how much a business or household spends on energy costs, especially if they use a lot of light.

Factories, stores and even schools or hospitals are taking advantage of energy efficient benefits, and maybe you should consider them as well.

You can simply replace existing bulbs with LED as they burn out, and you will be amazed at their efficiency, consistent brightness and overall performance.

Not only that, but the quality of the light is great and easier on the eyes. 

Best of all, operating costs on your back pocket and the environment are very low.

You can always see a huge decrease in your monthly electric bill as soon as you swap to LED lights.

LED light bulb use about 90% less energy than traditional bulb, and they last about 25 times longer.

This is no joke, and as technology improves, so do these numbers.

Consider the aggregate savings you can experience over the course of time from reduced energy costs as well from not having to replace bulbs as frequently.

Think about the positive environmental effects you can achieve just by swapping over the light bulbs you use.

They are easy to install and maintain, and it only takes about two or three months to recover from the initial investment in most cases.

You don’t need to invest in a lot of retrofitting or other expensive modifications, and the transition can begin as soon as new bulbs are installed.

Working with the right consultant, vendor, supplier or retailer can connect users with more savings as well.

This is definitely a winning opportunity that any property owner should consider, and the annual savings can be remarkable.

As people and businesses look for ways to help save the environment, this is an easy solution that requires minimal investment or time.

LED light bulbs are being installed in buildings around the world, and their quality is identical, if not better than traditional bulbs.

Investing now can begin to introduce savings that can span decades. 

Factories, schools and public buildings have all been introducing LED systems over the last few years and the proof is in the pudding, so to speak.

This is a reliable and efficient option that is saving people tons of money while creating a more comfortable environment to work, study and live in.

Let not forget the massive impact on carbon emissions you can make just by swapping light bulbs.

Take the first step and discover how you can find the perfect LED light bulbs for your particular needs for prices that are surprisingly reasonable.

You can stop replacing bulbs and throwing money out the window simply by upgrading your lights to include LED.

This technology is here to stay, and it will only get better over the course of time.

Whether you want to replace home lighting, ceiling or lobby lights or you want to upgrade your elevators, entry, stairwell or emergency systems, using LED bulbs provides better light for less money, and at a smaller environmental cost.

Do your research to make sure you are getting the best prices available by going to your local hardware store as well as searching the internet for the best deals.

Make sure to work with a retailer who can provide your home or building with the best solutions, and you can save more money and get started on this project today.

Whether you are going to change bulbs one by one or do everything at one time, each old bulb you discard and replace will lead to more comfort, money in the bank and a better future for your children.
