The advantages of LED chips:
The generating efficiency of LED chips is 180-210LM/W and that of ordinary LED chips is only 80-90LM/W. The life span is 50.000hrs. The voltage of solar panel is 5V. We adopt the spectrum chip with excellent weak light power generation effect which can work in cloudy days. Light sensor intelligent control which means the solar light will be up automatically at night and be off automatically by dawn. Any quality problems with the main components can be solved for free and we shall bear the costs of sending back and forth.
