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.
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. Read this guide for some tips and advice on low energy lights.
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’.
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The modern incandescent light bulb that has been around since the 1920’s has largely been replaced by LED technology (Light Emitting Diodes).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.
