Energy-saving lamp main technical term - working voltage

It refers to the voltage required for energy-saving lamps to work. Normally, our countries and most countries in Asia are 220v (except Japan and South Korea), Europe is 230v, Australia is 240v, North America (USA), Japan (South Korea) and most The South American countries are 110v and DC 12V, mainly for use on ships or on solar energy. In addition to the voltage, the power supply also has a frequency requirement. The general frequency is 50Hz or 60Hz. However, the frequency has little to do with energy-saving lamps. Usually, the energy-saving lamps produced by our company can work normally within the range of -20% to +10% of the working voltage, such as 220V, then the ratio is calculated as: 176v-242v normal voltage operation, which avoids some countries because the voltage is not The large number of energy-saving lamps caused by the stability is broken. It is important to state that the more stable the power supply, the longer the service life; the fewer the number of switches, the longer the life expectancy.
