LED lights compared to energy-saving lamps in the end who is more economical?

Our 3W LED lamp is 120 yuan, and the commonly used 12W energy saving price in the market is about 20 yuan.

If we turn on 8 hours of energy-saving lamps every day, it is 0.096 kWh per day, and 8 hours, our 3W LED lamp is only 0.024 kWh, which means that it saves 0.072 degrees per day and saves 26.28 degrees per year.

LED lamp cup life is greater than 50,000 hours. The energy-saving lamp is only about 5000 hours (only 10% of products in China can achieve this effect). In contrast, 1 year 12W energy-saving lamps probably use two.

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

The 8-hour LED light cup is used every two years to earn back the cost. LED lamp cup life of more than 50,000 hours home can use about 10 years. Then the cost of electricity and lights for the next eight years was earned.

You can think of how much the toll and lost time spent on the purchase of two 12W energy-saving lamps each year. There are many harmful effects of heavy metals in ordinary energy-saving lamps.

From which we can reflect the problems of the LED industry:

On September 22, 2010, Discovery Semiconductor announced yesterday a new generation of narrow-band optical receivers that support applications from 54GHz to 67GHz. The product can output -10dBm RF output power or 200mV peak-to-peak voltage, supports 1310nm and 1550nm wavelengths, power gain is 20dB, power consumption is less than 200mW, and it also has low-amplitude amplification characteristics in-band. Discovery said that this product can be applied to V-band RF optical fiber links to improve the wireless transmission performance of satellite communication systems, microwave optical communication systems, and remote sensing antennas. Professor Christina Lim of the Department of Electronic Engineering at the University of Melbourne stated that Discovery's high-frequency optical receiver is an excellent photoelectric converter and its gain is sufficient for the application of a 60GHz channel RF fiber system. With this product, they achieved error-free transmission of 1.8 Gbps BPSK signals at 60 GHz and received optical power of -9 dBm.
