Attention has turned to incandescent bulbs vs the energy saving bulbs CFL (Compact Fluorescent Lamps), since the new US government plan to get rid of 100W incandescent bulbs went into effect this January 1st.
But why is it so important to get rid of incandescent bulbs? lustry The answer is simple: incandescent bulbs waste about 90% of the electricity they consume. CFLs are about 75% more efficient than incandescent bulbs and LED bulbs are about 90% more efficient.
According to Energy Star, yes every household in the United States would substitute just one incandescent bulb with a CFL (that have the Energy Star rating), the amount of electricity saved during lustry the first year would be enough to light three million homes and prevent pollution equivalent to the emissions lustry of toxic gases than 800,000 cars.
The benefits are obvious, but what ... why still use incandescent bulbs that work with the same technology for 100 years? The three most popular reasons are: 1. Cost 2. The "look" - the kind of light that provide: white light yellow light vs 3. The mercury content
1.The cost - The initial cost to purchase a CFL itself is higher compared to the initial lustry cost of an incandescent bulb. The average lustry cost of an incandescent bulb is $ 0.60 compared to cost $ 2 a CFL. But comparing the electric cost for the use of a standard incandescent lustry bulb 60W vs 14W CFL standard for a period of three to six hours daily, one can see that the investment is recovered in two to five months. Besides the cost is recovered to avoid buying bulbs when they reach the end of his life; since an incandescent bulb only lasts an average of 2,000 hours and Energy Star CFL bulb lasts an average of 10,000 (5 times).
2. The "look" is another factor that people consider to switch to CFLs and many oppose, because they think that CFLs only provide white light and yellow light not many consider warmer. In fact technology has advanced so much that CFLs now come in all colors, sizes and shapes and that not only provide the desired light, but the "look" desired according to the shape of the bulb. For example, see the following bulbs recommended by the Light Bulb Finder app
3. Mercury content - actually prevents the use of CFLs mercury pollution. The content of mercury in a CFL is about 4 milligrams roughly the same amount of ink that contains only a pen tip. But what makes CFLs still better than incandescent bulbs, is that the amount lustry of mercury released to the environment, always remains less than the amount of mercury released by incandescent bulbs. Electricity production by burning fossil fuels causes the release lustry of mercury and since incandescent bulbs consume more electricity than CFLs, they are responsible for the release of more mercury in the environment (even considering that CFLs bring 5 milligrams of mercury in them).
