Energy Efficient Lighting and Why You Need It

According to Which, a leading research lead consumer magazine in the UK, lighting accounts for 18% of a typical household electricity bill, and if your electricity bill is anything like mine - around £1000/$1400 per year, then it is perfectly possible to reduce this bill by around 50% which could lead to savings of around £100 - and of course bigger houses could potentially make bigger savings

If you want to reduce your lighting costs there are a number of ways you can do it - the simplest way is by using your existing lighting more efficiently (by turning lights off for instance when you don't need them) or by implementing energy efficient lighting

What is Energy Efficient Lighting?

I have been doing some research on energy efficient lighting both for my own household purposes and also for the purposes of this blog, so here is what I have

Efficient lighting, or energy efficient lighting, is a term to describe lighting technology that lets you get the most out of your energy consumption

You can also say that you will achieve the same lighting comfort or brightness while using much less energy than you consume with your traditional lighting.

Imagine lighting up your house like you always do, but using less than half of your usual energy consumption for lighting.

Using energy efficient lighting alone throughout your house could save you around 50% of your overall lighting bills - and the good news is that energy efficient light bulbs last much longer than your traditional lightbuld

So Why Don’t Most People Use It Energy Efficient Lighting?

So if you can save this much, why is it that most people are not using efficient lighting?

The answer is simple: it’s because of the initial cost of acquiring energy efficient lighting bulbs.
Since efficient lighting technology is still in its early stages, efficient bulbs are more expensive than traditional bulbs.

But just because energy efficient lighting is expensive, it doesn’t mean using traditional bulbs is cheaper. There are lots of advantages to using efficient lighting that will make your initial investment look like a small price to pay.

For a start they much longer -energy efficient bulbs can provide lighting for an amount of time equivalent to at least 2-3 traditional bulbs, and some around 10 years - so even if efficient bulb costs around twice as much as traditional bulb, it is much cheaper considering the time and effort you can save from not purchasing and replacing traditional bulbs.

Again, from which

  • Saving: For each light bulb replaced with an energy-saving equivalent you can save around £3 per year, or £55 over the life of the bulb, according to the Energy Saving Trust.

Multiply this by the number of bulbs you have in your house and you can get to appreciate the sort of savings which are possible

Energy Efficiency

This is the main reason why efficient bulbs were developed. Efficient bulbs can illuminate your house with the same intensity as traditional bulbs by using only 1/8 of the energy. The efficiency varies, though, depending on the brand and materials.

The reason this is possible is because most of the energy the efficient bulb uses is converted to light. In contrast, traditional bulbs uses around 80% of the energy to produce heat instead of light.

There are also fewer environmental effects - since efficient lighting produces less heat, it follows that it also produces less carbon dioxide, a chemical which is bad for the environment. If you want to contribute to preventing global warming, then you can do it by simply using efficient bulbs.

Common Types of Energy Efficient Lighting

Now comes the confusing bit.

There are three common types of energy efficient light bulbs. You can choose among fluorescents, LEDs, and halogens.

  • Fluorescent lamps are considered to be the first efficient bulbs. Fluorescent lighting was discovered in the 19th century and has greatly developed since then. A fluorescent lamp contains mercury, which produces light when electricity passes through the tube. The most notable feature of the fluorescent lamp is its ability to distribute light evenly across the room due to its large light source.
  • LED, or light-emitting diode, is another type of efficient lighting. LED is a semiconductor light source. Although it was primarily used as an indicator lamp, new innovations in LED technology have made it possible for it to be a primary light source in your home. Aside from the advantages of efficient bulbs, LED is much more capable of resisting shock and frequent on-off cycling than other types of efficient bulbs. It does not contain mercury, so it is much less toxic than fluorescent lamps - and regardless of its shape, it can produce the same amount of light.
  • Halogen lamps or tungsten halogen lamps are an innovation in attempting to develop efficient incandescent lighting. They are more efficient than traditional incandescent lamps, but less energy efficient when compared to fluorescent lamps and LEDs.

These are just the basic facts about efficient lighting. If you want to know more about the types of lighting and detailed advantages of each type, you can find more details on the Internet.

However, now that you know the major advantages of efficient lighting, you should start considering this lighting technology for your home. Just find out which type is most suitable for your housing conditions and weigh up the initial costs and investment against the long term savings

With these advantages, you can save energy, save cash (and help save the earth) just by implementing energy efficient lighting
