With the advancement of technology and the improvement of people's living standards, traditional incandescent lamps and energy-saving lamps are gradually withdrawing from the historical stage. Instead, it is an outdoor luminaire with high brightness, low power and long life. However, users may find that when they choose to buy outdoor lamps, the price difference between outdoor lamps of the same size and appearance can reach dozens or even hundreds of yuan.
