The price/performance ratio of LED lights and energy-saving lamps

If our 3W LED lamp cup is 120 yuan, the 12W energy-saving price on the market is about 20 yuan.

If you light up 8 hours a day, energy-saving lamps 12W is 0.096 kWh per day, and 8 hours our 3W LED lights are only 0.024 kWh, which is 0.072 degrees per day and 26.28 degrees per year.

LED lamp cup life is greater than 50,000 hours. Energy-saving lamps are only about 5,000 hours (only 10% of China's products can achieve this effect). In comparison, 1 year 12W energy-saving lamps probably have to use two.

Then a 3W LED lamp cup saves 26.28 degrees *1 yuan / degree + 2 * 20 yuan / branch = 66.28 yuan per year than the 12W energy-saving lamps used by everyone.

Earn the cost of using the 8-hour LED lamp cup for two years. LED lamp cup life is more than 50,000 hours, the home can be used for about 10 years. Then the electricity and the cost of the lamp for the next 8 years is earned.

Think about how much the toll and lost time spent on buying 2 12W energy-saving lamps every year. There are many harmful heavy metals in the ordinary energy-saving lamps.
