LED lighting – the new revolution

LED lighting – the new revolution

In the past few years, lighting has come a far way. From the simple incandescent bulb, we have now reached LED lighting, and a revolution in lighting has suddenly hit us.

We all know the incandescent bulb that blew every few weeks and then had to cool down before you could swap it out or it would burn your hands. These bulbs were typically 60 or 100 Watt bulbs, and almost gave off more heat than light. As energy wasters they received a lot of bad press lately, but they were the first lights that we had in our homes, and they lit the way for decades.

With the advent of the fluorescent light however, I must say I was only too glad to bid the incandescent light goodbye. Suddenly a bulb did not need to be changed every few weeks. Instead they would burn for months or even years at a time. And of course they used only a quarter of the power, and less than that. A 14 Watt fluorescent globe gives off a lot of light, much more than a 60 Watt incandescent globe. They are also much cooler, meaning that less energy is wasted.

Writing this without diving into the world of mathematics to explain how much power is saved is difficult, but let’s keep it simple, shall we?
Even though the Fluorescent globe has only been with us for a few years, we are suddenly hit by a new phenomenon, the LED.
The acronym LED stands for Light Emitting Diode. They are the same thing as those little red or green lights on your TV which tell you whether the TV is on or off. These lights first made their appearance in hand held torches, and were loved because they gave off a massive amount of light, while using very little battery power, so now the batteries in a torch would last a long time. For a long time though, they were not used for indoor lighting because of the poor quality of the light they gave off. The light from the LED had a strange blue shine, and was not considered to be good for household use.
Now, however, all that has changed. The lighting companies have cracked the LED secrets, and you can now have LED lighting in your house. Although the initial installation costs of LED lights are huge, you will probably never have to replace them.
On top of all these good things, the LED uses a fraction of the power that a fluorescent bulb uses, so you get an immediate saving on your electricity bill. And the good news does not stop there.
Because LEDs uses so little power, they are a viable option of alternative energy. With incandescent or fluorescent lights, backup battery systems would soon run down if the main power source was lost, meaning that power had to be used sparingly.
LEDs use very little power, meaning that even if the power is down for hours at a time, you will still have a lot of light.
The LED lighting technology, like all new technologies, is still quite expensive. Like new technologies however, the price will keep on coming down until it stabilizes at an affordable level. But now is the time to start doing your homework, and be one of the first ones to make use of this great new technology.
