Return on Investment for LED Lights compared to Incandescent & CFL

Labels: , ,

As we all know LED Lights are becoming popular due to various benefits it can offer. There has been lot of emails and questions regarding how much electricity can be saved and what will be the payback when compared to CFL and Incandescent lights.


Comparing 60 Watts of Incandescent Lights with CFL/LED that can produce same amount of light (Lumens):

Global Warming & LED Lights

Labels: , , ,

Global Warming is defined as the increase of the average temperature on Earth. As the Earth is get hotter, disasters like hurricanes, droughts and floods will be frequent as per the research.

As per the research, global warming proportionately increases with increase in green house gases like

  • Carbon dioxide
  • Methane
  • Nitrous oxide

Some of the major cause of global warming is

  • The major source of carbon dioxide is the power plants. These power plants emit large amounts of carbon dioxide produced from burning of fossil fuels for the purpose of electricity generation.
  • About twenty percent of carbon dioxide emitted in the atmosphere comes from burning of gasoline in the engines of the vehicles.
  • Buildings, both commercial and residential represent a larger source of global warming pollution than cars and trucks. Building of these structures requires a lot of fuel to be burnt which emits a large amount of carbon dioxide in the atmosphere.
  • Deforestation kills the lungs of the earth

Tips on reducing global warming

Easiest and fast way of reducing the use of electricity is to move to high energy efficient lights like CFL’s. It uses very less energy compared to incandescent bulb. To reduce the power consumption even further we can use LED based lighting.

LED lamps can be used in
  • Office Lighting
  • Shop Lighting
  • Industrial Lighting
  • Hospitality Lighting
Advantages of using LED Lights

  • It lasts Longer than compact fluorescent lamp and much more longer than incandescent lamps.
  • LED are solid state devices, so they do not have filament. They are not damaged as easily as the other type of lamps and can withstand jarring and bumping.
  • They produce very less heat when compared to incandescent lamp. LED produces 3.4 btu’s/hourcompared to incandescent lamp producing 85 btu’s/hour
  • Mercury and Lead Free, No mercury is used in LED’s
  • LED lights are more efficient because it uses less electricity and gives more power. During this time of writing the article LED’s where able to give 140 Lumens per watt when compared to 13.8 Lumens/watt Incandescent lamp.
  • Cost of Ownership for LED is less compared to other lights. A 100-watt Incandescent light bulb uses 101.5 watts of electricity. Over a period 50,000 hours it will use 5,075 kilowatt-hours of electricity in addition to replacing it 50 times with a new bulb. To get the same lumens LED lamp will use 540 kilowatt-hours of electricity. Even though the upfront cost of LED is high but the cost of ownership is less.
  • LED Lamps are best suited for remote areas as it takes up less electricity so it can be used with solar panels replacing generators or running long electric lines.
