The city government said that the energy saving rate of LED lamps used this time is as high as 50%, which is the highest energy saving rate among current LED lamps. After the city's estimated replacement, it can save 1.6 million kWh of electricity a year, reduce carbon emissions by 100 metric tons per year, save 4 million electricity bills, and return to the company in three years. The city said that this is a trial-and-error nature. If the results are good, the future will be promoted.
It is reported that the parking lot uses T8-40W lamps that are not available now. Originally, all the lamps should be replaced with T5 lamps, but the Energy Bureau of the Ministry of Economic Affairs of Taiwan has subsidies this year, and it is better to switch to LEDs. A set of T5-28 watt lamps is more than 400 yuan, and the set of T8-LED-18 watt lamps used this time is about 1021 yuan, 2.5 times that of the former. However, the energy saving rate of T5 lamps is only 25%, and the service life is only two years. The energy saving rate of T8-LED lamps can be as high as 50% and the service life is about 4 to 5 years.
