When you flip a switch to light up a room, do you ever stop to consider the small piece of technology that makes it all possible? That seemingly insignificant light bulb results from centuries of scientific discovery and technological advancement, and the type of bulb you choose can have far-reaching implications. From energy efficiency and cost to environmental impact and even the overall mood of your space, the decision between LED and incandescent bulbs is more significant than you might think.

In Australia, as in many parts of the world, we’re shifting from traditional incandescent bulbs to LEDs, driven by a growing awareness of energy conservation and sustainability. However, many homes and businesses continue to use incandescent bulbs due to a need for more information or an appreciation for their classic, warm light.

In this blog post, we’re here to shed light on the key differences between LED and incandescent bulbs. By comparing their energy use, cost, environmental impact, and more, we aim to help you decide on the best lighting solution for your needs. Whether you’re outfitting your home or your business, understanding the pros and cons of these two types of bulbs can help you save money, reduce your carbon footprint, and even enhance the look and feel of your spaces. Ready to flip the switch? Read on!

What are Incandescent Bulbs?

Incandescent bulbs have a long history, not only in Australia but across the globe. Invented by Thomas Edison in the 19th century, these bulbs produce light by heating a wire filament until it glows. They’re the traditional bulbs many of us grew up with that give off a warm, inviting glow.

Incandescent bulbs are widely used for a variety of applications, like residential lighting, decorative lighting, and large-area lighting. They’re widely loved for their warm light and low upfront cost. However, they’re less efficient than some of the more modern options available today.


What are LED Bulbs?

LED stands for Light Emitting Diode. Instead of using heat to produce light like incandescent bulbs, LEDs emit light when an electrical current passes through them. They’ve been around since the 1960s but have seen a surge in popularity in recent years due to their increased efficiency and longevity.

LEDs are used in numerous applications, from household lighting to electronics and even in traffic signals. They’re more expensive upfront compared to incandescent bulbs, but they make up for it with their energy efficiency and lifespan.

Comparing LED and Incandescent Bulbs

Energy Efficiency

LED bulbs are the clear champions in terms of energy efficiency. They consume up to 75% less energy than incandescent bulbs. To put this into perspective, a 60-watt incandescent bulb can be replaced with a 10-watt LED bulb. 

Despite the vast difference in power usage, both bulbs will deliver the same amount of light. This energy efficiency is due to the different mechanisms by which these bulbs produce light: incandescent bulbs heat a filament to produce light (much of the energy is wasted as heat).

At the same time, LEDs emit light through the movement of electrons in a semiconductor material. Over the years, this efficiency can lead to significant energy and cost savings for both households and businesses.


When considering the cost, you need to look beyond the initial purchase price. Yes, incandescent bulbs are usually cheaper to buy, but they also have a shorter lifespan and higher energy consumption. 

These factors mean you’ll replace them more frequently, increasing your energy bills. Although pricier upfront, LED bulbs last up to 25 times longer than incandescent bulbs and consume far less energy. So, over time, you’ll spend less on replacements and energy bills, making LEDs a more cost-effective choice in the long run.


Environmental Impact

The environmental impact of your lighting choice is another critical aspect to consider. LEDs, with their lower energy consumption, are the more eco-friendly option. They contribute less to greenhouse gas emissions since less power is required to operate them. 

Plus, their longer lifespan means less waste ends up in landfills. Conversely, with their higher energy use and shorter lifespan, incandescent bulbs emit more CO2 and contribute to more waste.

Brightness and Colour

When it comes to brightness and colour, both LEDs and incandescent bulbs offer a range. You can choose from soft, warm light to cool, daylight-like illumination. However, LEDs have an edge in terms of versatility. They provide options like dimmable lights and smart bulbs that can change colours at the tap of a smartphone app, allowing you to customise your lighting to suit your mood or the time of day.

Heat Emission

Have you ever accidentally touched an incandescent bulb that’s been on for a while? It could be a more pleasant experience. 

Incandescent bulbs can get quite hot because they waste a significant portion of their energy as heat. This can be a safety concern, especially in areas where heat build-up can be an issue. LEDs, on the other hand, run much cooler. 

They emit very little heat because they’re much more efficient at converting energy into light. This makes LEDs safer, particularly in environments where temperature control is crucial.

Which Is The (B)Right Choice?

It’s clear that LEDs offer numerous advantages when comparing LED and incandescent bulbs. They’re more energy-efficient, cost-effective over the long term, and environmentally friendly. Plus, they offer a level of versatility and safety that incandescent bulbs can’t match.

While the warm glow of incandescent bulbs has its charm, the long-term benefits of LED bulbs – both to your wallet and the planet – simply can’t be ignored. Switching to LED lighting is a bright idea that illuminates your spaces, lightens your energy usage, reduces costs, and lowers your environmental impact. It’s a small change that can make a big difference.

What makes LED bulbs more energy-efficient than incandescent bulbs?

LED bulbs are more energy-efficient because they convert a higher percentage of electricity into light. Unlike incandescent bulbs, which waste a lot of energy as heat, LEDs use almost all their energy to produce light, making them much more efficient.

Are LED bulbs more expensive than incandescent bulbs?

While the upfront cost of LED bulbs is typically higher than that of incandescent bulbs, the total cost of ownership can be lower. This is due to the longer lifespan and lower energy consumption of LED bulbs, which result in lower replacement and energy costs over time.

How much longer do LED bulbs last compared to incandescent bulbs?

On average, LED bulbs can last up to 25 times longer than incandescent bulbs. While an incandescent bulb might last about 1,000 hours, an LED bulb can last for 25,000 hours or more.

Are LED bulbs better for the environment?

Yes, LED bulbs are generally better for the environment. They consume less energy, which reduces greenhouse gas emissions from power plants. They also have a longer lifespan, which leads to less waste because they need to be replaced less often.

Can I use LED bulbs in fixtures that currently have incandescent bulbs?

In most cases, yes. LED bulbs come in various shapes and sizes and are designed to fit into existing fixtures. However, it’s always a good idea to check the fixture’s specifications to ensure compatibility. If you’re unsure, reach out to a professional like Your Electrical Experts for advice.
