How Much Money Will a CFL Light Bulb Save Me
A single CFL light bulb will save you $28.23 every year! That’s right just changing 1 incandescent light bulb to a compact fluorescent light bulb will save you $28.23 every year! How energy efficient is that?
By switching or replacing all of your lights in your home to CFL light bulbs will greatly reduce the amount of electricity usage in your home! Some of you may think these CFL light bulbs are expensive, they are not! I will do a break down of the cost to purchase CFL light bulbs and also the cost to run these CFL light bulbs in your home so you can see a comparison between CFL light bulbs and your regular incandescent light bulbs. Scrool down to the chart comparing CFL vs. incandescent bulb.
What is a CFL Light Bulb
The term CFL stands for Compact Fluorescent Light. I’m sure you’ve seen fluorescent lights before, they are long tubes. Well these CFL bulbs are very similar, but they are a smaller diameter tube that is spiraled to take up less room, but still give off enough light, and save electricity.
How Much do CFL Light Bulbs Cost
Compact fluorescent light bulbs costs anywhere from $1 – $3 each, depending on where you buy them and what brand you buy. On average you will find them for about $1.50 in most stores. Remember to buy CFLs in packages and online, they are usually cheaper this way. Buying CFL light bulbs individually may get a little expensive, but will still pay for itself!
How Much Electricity Do CFL Bulbs Use
Your average CFL light bulbs will consume 13 watts of power and still give off the same amount of light as a standard incandescent light bulb that consumes 60 watts! This means that your regular incandescent light bulb will use 4.6 times the amount of electricity than a CFL bulb, which means the CFL will save you 4.6 times the amount of money to use it! These CFL bulbs are very energy efficient!
Why are CFL Bulbs more Efficient than Incandescent Bulbs
CFL 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 bulbs use a different technology to produce light. CFL 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
I will give you a break down of the initial cost to buy these light bulbs and how much it cost to run the light bulbs. I will give you actual numbers of measurements and prices of these bulbs so you can see how much money you will save using CFL light bulbs vs. incandescent light bulbs!
|13w CFL bulb||60w Incandescent Bulb|
|Cost to Purchase 1||$1.50||$0.50|
|Buy in Next 5 Yrs||1||10|
|Total Purchase Cost||$1.50||$5.00|
|Total Cost over 5YR||$39.564||$180.68|
Now let me break down this chart for you, CFL bulbs will last for at least 5 years! Most CFL bulbs are rated 5 – 7.5 years! So in the next 5 years you will only need to buy 1 CFL bulb, where an incandescent light bulb will last around 6 months so in the next 5 years you will have to purchase 10 of them to last as long as the CFL bulb!
The cost of electricity to run them is based on the light being on for 16 hours a day, every day for 5 years and $0.10/kWh which is average, but you can look on your electric bill and see what you are paying. Most likely this would be a kitchen, living room, or dining room light. Which actually most of you probably have a ceiling light that holds 3 – 5 lights in it not just 1!
As you can see with this chart that the CFL bulb is way cheaper in initial cost and in electricity usage! Remember this is only 1 light bulb running in your home that will save you $141.12 in 5 years, that’s $28.23 every year in savings! Now think how many lights are turned on in your home right now!
