why people still use inefficient incandescent light bulbs
1. the United States will no longer produce or import incandescent lamps, although the products in stock can still be sold in stores.
Phasing out is the result of a shift in federal rules to more energy --Efficient bulb. Energy-
The cost of an efficient bulb is higher than that of an incandescent lamp, but lasts longer, and saves energy costs over a long period of timeterm.
So why are people still buying incandescent lamps, what does it mean to you to eliminate them?

The effective choice is mainly energy-saving lamps (
Compact fluorescent lamp)and LEDs (
An incandescent lamp costs only 70 cents.
At the same time, a CFL bulb costs at least a few dollars, and the LED starts at $10, but usually around $20.
The problem with incandescent lamps is that you end up paying more for electricity.
Incandescent lamps are inefficient-90% of the energy goes to heat and only 10% to light.
It will not last, as long as the incandescent lamp and LED light.
Typical incandescent lamps last about 1,000 hours while 15-
The Watt CFL bulb lasts 10,000 hours, 12 hours
The watt LED bulb lasts 25,000 hours.
In other words, when the CFLs can last for 10 years and the led is up to 25, the incandescent lamp can last for about a year.
All in all, your energy cost can reach 25%.
Reduced by 80% by switching to energy
Efficient bulbs, according to Energy. gov.
Despite the savings, many people still insist on using incandescent lamps because they usually don\'t spend so much money on lighting at home.
Joe Rey said: \"There is not much motivation to improve efficiency because it will not have much impact on their electricity bills --\"
Barreau, a professor of lighting design at the University of Kentucky and a consultant to the American Lighting Association, talked about why some people have not turned to more energy. Efficient bulb.
While an office building may use 21% of the electricity to light, a house uses only 13% of the electricity, according to U. S.
Energy Information Administration
Home decoration store Lowe\'s made a comparative study on the electricity charges of LED and LED
The energy cost of the LED is $30 more than the bulb\'s 22-year lifespan.
The energy cost of using incandescent lamps during the same period has increased by $165-of course, but for many homeowners it may not be enough to change their buying habits.
Colored incandescent lamps are known for their warm light, which looks particularly good in terms of skin tone, Rey-Barreau said.
On the other hand, fluorescent lamps have a high reputation for their harsh blue light. Rey-
Barreau says this belief is a \"continuation\" of the light\'s original appearance \".
\"Today, you can have a fluorescent lamp that perfectly matches the incandescent lamp,\" he said . \".
Bulb manufacturers need to indicate the color temperature of the bulb on the label so that consumers know exactly what they are buying.
Some consumers complain that the life of CFLs is not as long as advertising.
Terry McGowan, engineering director at the American Lighting Association, said that one feature of the CFL bulbs is that they are \"fairly fragile\" and may overheat.
\"These life ratings are built in test labs, not in someone\'s living room equipment,\" McGowan said . \".
\"When you put them in a fixture and put them in the glass shade to the bottom of the bottle, they get too hot and their life is shortened.
LED lights will also overheat.
McGowan recommends using these bulbs in well-ventilated lamps and lanterns.
When CFL bulbs are often turned on and off, they are also vulnerable to a shorter life span.
The bathroom may not be a good place for CFL, for example.
The desk lamp, floor lamp or corridor lamp is more likely to extend the life of the CFL bulb, McGowan said.
Another complaint about non
This is how incandescent lamps look.
CFLs, in particular, uses a curly design.
\"The spiral shape of the CFL is very troublesome for some consumers,\" said Karen Cobb, a spokesman for Lao . \".
\"We heard from our customers that they said it was just an unusual shape and didn\'t look as good as an incandescent lamp in the light fixture,\" Cobb said . \". Rey-
If you can\'t see the shape of the bulb, the CFL\'s light looks no different from the incandescent light, Barreau said.
The reason for driving the use of cheap, inefficient incandescent lamps is simple because they are familiar.
\"This is what everyone knows most of their lives, and the whole energy efficiency issue has become more important over the last five or six years,\" Rey-Barreau said.
But led is becoming more and more popular.
At Lowe\'s, the number of LED bulbs sold in its stores doubled last year, Cobb said.
She said that one of every three bulbs currently purchased at Lowe\'s is a CFL or an LED bulb.
Cobb said that the popularity of LED is partly due to consumer familiarity with LED in other products such as TV and computers.
The price of LED bulbs also fell sharply.
The first LED bulbs on the market cost $30 each.
Now, some manufacturers offer LED bulbs for $10, Rey-Barreau said.
He predicts that LED bulbs will become \"default light sources\" as costs continue to fall \".
