This means that your regular incandescent light bulb will use 4.6 times the amount of electricity than a CFL bulbCFL bulb, which means the CFLCFL will save you 4.6 times the amount of money to use it! These CFL bulbsCFL bulbs are very energy efficient!

Why are CFL Bulbs more Efficient than Incandescent Bulbs

CFL bulbsCFL bulbs use a different technology to produce visible light. Your average incandescent light uses a small wire,known as a filament, to cross the negative – and positive + electrodes which cause the filament to heat up, so hot that the metal turns a bright white. Which also produces a large amount of heat! So in the summer you run your air conditioner to cool your home, yet your incandescent lights are heating your home causing the air conditioner to run longer and harder, which uses more electricity.

CFL bulbsCFL bulbs use a different technology to produce light. CFL bulbsCFL bulbs use a ballast to make electrical current flow through mercury vapour gases in the glass tubes. When electric current flows through the mercury vapour it causes the gases to produce pour ultraviolet light, or UV light, which is invisible to the human eye. The glass tubes have a phosphor coating on the inside, which the ultraviolet light emitted by the mercury vapour gases cause the phosphor coating to emit visible light. This method uses a lot less electricity to produce the light and also does not create a lot of heat!

How Does a CFL Bulb Compare to an Incandescent Bulb

    That very well maybe correct, but I show the math above, CFL bulbs still save you money using CFL instead of incandescent lights. Saves you in cost of replacement bulbs and in electric bill.

  2. Art Says:

    Here’s the kicker. The Great Light Bulb Controversy/Phase Out has nothing to with being green and is based on primarily on BS.

    Light bulbs were/are being phased out for one reason only, profit. The majors (GE,Phillips) fully admitted it was about money.

    You smugly pre-suppose I am one of the bad high income people to create a us good guys against the bad guy projection. I am not! The truth is I was the director of a City and County Building Inspection dept. and served on many code committees, to include one of the longest serving writers of the International Building Code. All of your arguement is based on a static population and light bulb companies and electricity providers will not allow population control(thats real green). Cfl (mercurydisposal is or will be secondary tax incometo greedy local gov’ts. CFL “Snake Oil” for the 21 Century!

    If you save energy you will pay less. If you want to pay to use more energy then that’s fine, but us average income people need to save money. If you look at the math above you will see these light bulbs are not high priced, they actually are cheaper. You replace them less often and they use less electric which makes your monthly electric bill lower, so you actually are saving money on buying less bulbs and less electric.

  7. Bull Exposed Says:

    Why save energy if I pay for it! The car dealer’s lot on the highway burns more energy in one night than My house burns in a month and resid. use subsidizes him.
    THIS IS NOT GREEN. It’s to sell high priced light bulbs
    The ignorant like being deceived.

    I think I already have an example on this page above that you can go off of. But if you like, let me know amount of bulbs you plan to replace and average usage and I can give you the information. Thanks.

    How would I calculate the return on investment on the example above ?


  10. Go Green In Your Home Says:

    If you read through the CFL bulb information above you will know what the difference is. What is special about CFL is that CFL bulbs are filled with gasses which burn, where regular bulbs short out a thin piece of metal heat it up so much where it glows white.
