As an intermittent lighting source with frequent switching, LED induction lamps can extend their service life by at least 5 times and save more than 90% of electricity under normal conditions. In some all-weather public lighting occasions, such as underground parking lots, the investment can be recovered in half a year only from the perspective of energy conservation, and the labor cost for frequent lamp tube replacement is also eliminated.
