The death of the light bulb

RIP light bulbThe incandescent light bulb has been with us for over one hundred years and, at last it seems that their days may be numbered thanks to the much more energy efficient LED (light emitting diode) bulbs that are now finding their way into homes and offices around the country.

For many families up and down the country the last couple of years have been a real financial challenge. The cost of living has increased whilst wages have struggled to keep pace. As a result many households have looked at ways of saving money.

During the winter our consumption of energy in the UK increases dramatically. The days get much colder and much shorter. As a result more people will heat and light their homes for longer periods which lead to bigger energy bills.

Unfortunately this has become much more expensive as the price of oil and natural gas has increased which is then passed on to you, the customer. Therefore being efficient as possible with your energy consumption is sure way of reducing bills.

Because LED bulbs are so much more efficient, governments and businesses around the world are increasingly turning to LEDs in order to save taxpayer money or increase profitability. In fact, Brazil and Venezuela started to phase-out using incandescent bulbs in 2005.

In 2009 the European Union, Switzerland and Australia started to phase them out. In 2012 Argentina, Russia and Canada will start to phase them out and finally in 2014 the United States and Malaysia will do the same. It is also hoped that China will by October 2016 all incandescent light bulbs will be banned in China.

The big question is why? Why are governments around the world abandoning incandescent bulbs and turning to LED lighting. The answer can be found in a Wikipedia which shows the following table:-

Incandescent Halogen Fluorescent LED
Purchase price $2 $4 $4 $20
Electricity usage 60 W 42 W 13 W 9 W
Lumen 660 570 825 900
Lumens/Watt 11 13.6 63.5 100
Lifespan (hours) 2000 3500 8000 25000
Bulb cost over 10 years $22 $28 $12 $20
Energy cost over 10 years – @15cents/kWhr $197.10 137.97 $42.70 $29.57
Total $219.1 165.97 $54.71 $49.57

*Comparison based on 6 hours use per day

The table above clearly demonstrates that over the course of an LED bulb’s lifetime it is much more efficient than fluorescent bulbs, halogen bulbs and incandescent bulbs. Governments, business and individuals have a fantastic opportunity to become much more energy efficient with their lighting.

The sooner governments, businesses and individuals adopt LED lighting the more money they will be able to save. Soon enough incandescent light bulbs will be a thing of the past, in the same way that cathode ray TV’s have largely been replaced  by LCD TV’s.

LED bulbs also have the advantage of being much more effective at lighting a room and creates different shades of light as seen in the picture below. Istoria LED is one such company offering a fantastic range of LEDs perfect for homes and businesses.
