1. The main feature of solar wall lights is that they can be charged automatically. When under the sun during the day, the solar wall lamp can use its own components to convert light energy into electric energy and store the electric energy, which is not possible with traditional wall lamps.

　　2. The solar wall lamp generally adopts intelligent switch control, and it adopts light control to automatically turn on the light. Generally, it will automatically close during the day and open at night.

　　3. Since the solar wall lamp is driven by solar energy, it does not require an external power supply or complicated wiring, and its work is very stable and reliable.

　　4. Long service life, solar wall lamp uses semiconductor chip to emit light without filament. Under normal use, the life span can reach 50,000 hours. In contrast, the life span of incandescent lamps is 1,000 hours and the life span of energy-saving lamps is only 8,000 hours. Solar wall lights can be said to have a very long life.

　　 5. We know that ordinary lamps contain mercury and xenon, and the used lamps will cause great pollution to the environment. But the solar wall lamp is different, it does not contain the two elements of mercury and xenon, so the waste solar wall lamp basically does not cause environmental pollution.

　　 6. Healthy. The light of the solar wall lamp does not contain ultraviolet and infrared rays. Even if the light is exposed for a long time, it will not harm human eyes.

　　7. Security. The output power of the solar wall lamp is completely determined by the solar battery pack, while the output of the solar battery pack depends on the temperature of the solar surface, which is the intensity of the sun's irradiation. The output power of solar cells per square meter is about 120 W under standard conditions. Considering the area of the solar panel, it can be said that its output voltage is very low, and it is an absolutely safe lamp.
