Choose The Best Lighting For Your Home

Did you ever think that changing the type of light bulbs you use in your home can give you a good saving of electricity? Here I am just going to focus on three types of bulbs.

The incandescent light bulb: 

These are the cheapest bulbs available costing around,$0.50 a bulb. They have a life time of 1000 hrs.

The CFL light bulbs: 

These bulbs are a bit more expensive at around , $1.20 a bulb (13 watts CFL bulb = 60 Watt incandescent light bulb)., these bulbs have a stated average lifetime of 8,000 hours.

The Led Type Light bulbs:

 These are bulbs using LED’S . since this is quite new it is a bit more expensive and it costs around $15.00 for a single bulb (7 watts LED bulb = 60 Watt incandescent light bulb). these bulbs have a stated average lifetime of 25,000 hours!

we know that we cannot estimate that the CFL and LED lights work for their stated hours so lets half the stated lifetime.

Therefore if we calculate the amount of money used to buy the bulbs alone for a 120,000 hr. period. We will need:

120 incandescent lights (considering 1000 hr. life span)= $0.5 *120= $60

30 CFL lights (considering an 4000 hr. life span) = $1.2 * 30= $36

10 LED lights (considering a lifespan of 12500 hr.) = &15.0 *10 =$150

Also consider the time you will spend in changing the bulbs. Time is Money.

Now let’s consider the energy utilized, assume the electric bill at a price of $0.12 per KW.

Therefore an incandescent bulb of 60w will use 7,200 kWh, i.e. $864 for 120000 hrs.

A CFL Light bulb of 13w will use 1569kwh, i.e.  $187.20 for 120000 hrs.

 A led Light bulb of 13w will use 840kwh, i.e.  $100.80 for 120000 hrs.

Let us conclude the total money required for a period of 120000 hrs:

Incandescent bulb will require $60 for the bulbs + $864 for electricity = $924

CFL bulb will require $36 for the bulbs + $187.2 for electricity = $223.2

LED bulb will require $150 for the bulbs + $100.8 for electricity = $250.8

There you go, until LED bulbs are available for a much lower price, use CFLS and enjoy a greater savings. If you like the yellow light of incandescent bulbs buy the warm white type of CFLS, I am really surprised to know that many guys did not know that the CFLS are available which gives yellow light.
