light emitting diode bulb How Much Do Energy Efficient Bulbs Save?
In the total energy consumption of most households, bulbs are a simple and often overlooked factor.The Environmental Protection Agency reported that if every household in the United States uses only one standard incandescent lamp instead of an energy bulb,The country will save about $0.6 billion a year on energy costs--One year is enough to supply power to 3 million households (see ref 1 ).The compact fluorescent bulb (CFL) is the first alternative bulb to be widely used.They are more expensive than incandescent lamps, but pay for themselves during the life of the bulbs.CFLs have a wide variety of shapes and brightness to suit the needs of most homes.Most people know about spiral coils, but CFLs also have Flood, bulb and chandelier shapes (see ref 2 ).About energy saving lampFourth, the energy of standard incandescent lamps.This, combined with their longer service life, can significantly save costs.For example, the life of the CFL bulb is about 10,000 hours.During this period, it will use the electricity at 140 KW.At 20 cents per kilowatt hour, the CFL has a lifetime electricity bill of $28.In contrast, incandescent lamps last only 1,200 to 2,500 hours.If measured above 10,000-The service life of incandescent lamps is about 600 KW, which will cost US $120.The CFL will save $92 and $460 KW in energy during its service life (see ref 3 ).Light-LEDs or LED lights are newer options for residential lighting.They have much more energy.More efficient than incandescent or CFL bulbs.LED technology is nothing new.It has been used for Christmas lights, electronic panels and fancy pens for decades.LED bulbs are clusters of up to 180 individual LED bulbs encapsulated in diffuser (see ref 2 ).The biggest benefit of LED lighting is its life.LED bulbs will last about 50,000 hours--Five times longer than the CFL bulb.If the bulb is kept for eight hours a day, it will last for more than 17 years.During the service life, the LED bulb will use 300 KW of the power.20 cents per kilowatt hour, the life of the LED bulb is $60.In contrast, you need five CFLs to match 50,000-Hours life of LED.The five CFLs will use 700 KW hours of electricity at a cost of $140.Compared with CFL, LED bulbs save 400 KW mAh of power and 2,700 KW mAh compared to incandescent lamps.This saves $80 more than the CFL bulb and $540 more than the incandescent lamp (see ref 3 ).
