1. LED, high-capacity lithium battery, all-in-one controller.
2. Use solar energy as a power source, which is a good resource that is being continuously developed.
3. High-capacity lithium battery: high power, long use time, light weight, green resources, and will not cause any harm.
4. Using LED lighting, no diffusion effect, high light efficiency, plus a unique secondary optical design, can be Illuminating to a wider area again improves the light efficiency and achieves the purpose of energy saving.
Polycrystalline silicon solar panels, which are easier to manufacture, save power, and have low overall production costs.
