It can be directly driven by the mains, and most products have wide voltage input, which can be input from AC85~270V. Traditional incandescent lamps (tungsten filament lamps) have high energy consumption and short lifespan. Under the environment of global resource shortage, their production has been gradually banned by governments around the world, and the alternative products are electronic energy-saving lamps. Although electronic energy-saving lamps have improved the energy-saving effect However, due to the use of many heavy metal elements that pollute the environment, it is contrary to the general trend of environmental protection. With the rapid development of LED technology, LED lighting has gradually become the best choice for new green lighting. LED is far superior to traditional lighting products in terms of light-emitting principle, energy saving and environmental protection.
