Advantage 1. The outstanding advantage of the solar sensor wall light outdoor light is that under the sunlight during the day, the solar sensor wall light outdoor light can use its own conditions to convert solar light energy into electrical energy, so as to achieve automatic charging, and it will also store the light energy.   2. The solar sensor wall light outdoor light is controlled by an intelligent switch, and it is also a light-controlled automatic switch. For example, the solar wall light will automatically turn off during the day and automatically turn on at night.   3. Because the solar sensor wall light outdoor light is driven by light energy, it does not need to be connected to any other power source, so there is no need for cumbersome wiring. Secondly, the solar wall light works very stable and reliable.   4. The service life of the solar wall light is very long. Because the solar wall lamp uses semiconductor chips to emit light, it has no filament, and its lifespan can reach 50,000 hours without being damaged by the outside world. The service life of incandescent lamps is 1,000 hours, and energy-saving lamps are 8,000 hours. Obviously, the service life of solar wall lamps far exceeds that of incandescent lamps and energy-saving lamps.   5. Ordinary lamps generally contain two substances, mercury and xenon. These two substances will cause great pollution to the environment when the lamps are discarded. However, the solar wall lamp does not have the two substances of mercury and xenon, so even if it is old, it will not pollute the environment.   6. Everyone knows that ultraviolet rays and infrared rays will cause damage to people's eyes after long-term exposure, but solar wall lights do not contain these, even if they are exposed for a long time, they will not cause damage to people's eyes.
