Do LED Bulbs Save Money?


Do LED bulbs save money? What are the best lamps to use? What does low energy mean and what are the implications for lowering your carbon footprint?

What is a low energy light, and should I use one? Does it save money to use one? A low energy light bulb for example, or a light fitting with an integrated LED typically uses lower energy than other bulbs. Modern designs and technology pull less electricity from an electricity supply, less than a standard light fitting such as a Halogen bulb.

It makes sense that in these eco-conscious times, we all do whatever we can to save energy and money, to live cleaner and greener lives. It doesn’t take a bright spark to realise that this means taking stock of the way we manage our homes, that includes thinking about the type of lightbulbs we use.

What are the best light bulbs to use? Well, there're different sort of bulbs, and some companies refer to 'lamps' rather than bulbs. So for example you'll find references online to all these common types of light:

Light Emitting Diode (LED)
Chip on board Light Emitting Diode (COB LED)
Surface mounted device Light Emitting Diode  (SMD LED)
Halogen lamps
Incandescent lamps
Neon lamps
Fluorescent tube
Compact fluorescent lamps
Metal halide Lamps
High intensity discharge lamps


But which type of lightbulb performs the best when it comes to value? Do LED bulbs save you money? 

Of course, it’s important for you to choose the right light bulb just as much as it is for you to select the right fitting or light shade. At Value Lights we’re lighting specialists and stock one of the biggest ranges of lights in the UK, so hopefully you can find something at our online store.

Here’s how LED bulbs work 

LED (Light Emitting Diodes) bulbs will save you money, but not only that, LED bulbs are also proven to last longer than the more traditional incandescent or CFL bulb designs. LED bulbs are much more efficient at turning electricity into light, so they need less energy to produce the same amount of light. This production of ‘light’ is often referred to as ‘lumens’.

Here're a couple of examples of typical LED bulbs currently in use:

What is a lumen? 

There’s a big technical explanation of what ‘lumens’ means, you’ll find plenty by just browsing the web but in short, lumen means ‘brightness’. Therefore, lumens is the amount of brightness a light source like a bulb emits. It is measured by a number system, the higher the number the brighter the lumens. There’s a chart below showing you the numbers.


The difference between lumens and wattage (promise it’s not boring) 

The modern incandescent light bulb that has been around since the 1920’s has largely been replaced by LED technology (Light Emitting Diodes). Its technology goes back even further to 1880 when the carbon filament lamps were developed.

The sales of incandescent bulbs have been in serious decline in western countries during the last 20 years and across the middle east due to their low energy efficiency. Much of the input energy ends up as heat so it’s understandable these types of bulbs are no good in warmer climates. Although there is some benefit to colder climates, these bulbs really aren’t environmentally friendly.

The wattage required to light a modern LED bulb is much lower than the old incandescent ones, which is why they save you money. The only argument against modern bulbs is that they are not as bright as the older bulbs – but this isn’t strictly true as it depends on the bulb you buy, and the style of light fitting. So therefore, wattage is the amount of electricity needed to light a bulb.

Lumens refer to the level of brightness that the bulb can achieve.

With the older incandescent light bulb, a higher wattage meant a brighter bulb but newer technologies like LED’s, use less energy (wattage) to produce the same amount of light, ultimately saving you money.

In a nutshell, to get a general understanding of how much light a bulb produces, we now use lumens to measure a level of brightness.

So for example this top seller, the MiniSun 4 Watt ES/E27 Filament Pear Shaped Bulb in Warm White, shows on its webpage the description that it produces 440 lumens of light. If you navigate to any product page on our website, every product has a description – click on the link and the description will open up and provide you with the lumens number.* See the chart below.

Remember that lumens and wattage are different – the former refers to brightness, but the latter refers to energy consumption.

Another helpful example, imagine you want to find a bulb that provides you with the same amount of brightness as an old incandescent 60W bulb. The MiniSun Thermal Plastic 7W SMD GU10 6500K provides a very bright 600 lumens but for only 7 watts of energy! You can see how the technology has developed to be more energy saving.

Use this table as a guide, while the table doesn’t tell you exactly which bulb to get you can use it as an indication of what sort of wattage is available depending on the lumens you require, which will help you calculate how to save money:

How much money could you save? 

Using LED bulbs to light your home can mean consuming just 10% of the electricity you would need if you were using regular lightbulbs. The result in terms of how much money you could save is an incredible 90% - now that’s a pretty good return on your investment!

Plus, by using LED’s, you are doing a little more to help save the environment. The New York Times recently reported that if all American households switched to LED lighting, it would be the equivalent of “taking several millions of cars off the road”.

You can now buy LED bulbs in a wide range of shades, shapes and sizes. This means that you can get an LED bulb to fit any type of ceiling light, mounted, floor or table lamp, for any room. It isn’t just a money-saving exercise, LED lighting also looks attractive, and they produce light instantly without having to warm up - they’re a welcome addition to any modern home.

Prices range from £4.99 up to £9.99. However, the design and build quality of all LED bulbs are very high. The more you pay, the more functionality or style you get.


Are there any safety concerns? 

No! Using LED lighting is a far safer way to light your home – why? Well, because LED bulbs turn almost all the electricity they use into light, they don’t get hot. In fact, they produce very little heat at all, and this makes them safer. Also, all LED lighting currently sold in the UK adheres to EU standards and regulations.
