Experts Recommend Led lights for the high cost performance
At president, incandescent lamp is facing with the situation of dying out. energy-saving lights and LED lights are becoming the main lighting products on the market. Many people think the incandescent lights are cheap so they have the higher cost performance. Other people think energy-saving lights are of higher cost performance. Some also think Led lights are of higher cost performance. So the question now is which light has the highest cost performance.
Investigation: the similar support rate of energy-saving lights and led lights
Before experimental testing, we ask several people the question. Mrs. Green said she thought Led lights were brighter. Mr. White said he would still use incandescent lights because the price is very cheap. Miss Lee and Mr. Wood preferred Led lights.
Experimental tests: Led lights perform better in brightness and energy-saving
The experimental testing results are as follows:
Conclusion: Led lights have the highest cost performance
Generally, a family needs to open lights for about 6 hours a day. If per kw electricity needs 0.6$ (just assumption), a 40W incandescent light costs 47,98$ per year. A 10W energy saving light costs 10.69$ per year. A led light costs 9.25$ per year. Although Led lights are a little more expensive, we can still think they have the highest cost performance.
Experts Suggestion: Experts suggest students use led table lamps when studying
Incandescent use thermal effect of tungsten when lighting. Energy saving lights generate electromagnetic radiation which is harmful to children's eyes. Led lights does not contain electromagnetic radiation. So experts suggest using Led lights.
