Features:100% Brand New And High Quality within the daytime, mechanically turning at the lighting fixtures at night, and mechanically turning off the lighting fixtures at dawn, the output voltage is the output voltage when the battery has no voltage. The circuit controls the output by way of approach of detecting the artificial of the voltage generated via way of the photo voltaic panel, with out the desire for photosensitive elements; it is compatible for fairly lots of batteries high quality materials, the standard is guaranteed photo voltaic charge and discharge automatic control switch, suitable for a wide range of battery voltages and portable to apply in the course of the day, robotically activate the sunshine when it's dark, and routinely turn off the light when it's brilliant low-power controller is acceptable for photo voltaic backyard lights, lawn lights, colourful string lights, small avenue lights, etc: Color:GreenPackage Include:1PC*Solar management switch circuit boardNote: 1 enable zero versions thanks to handbook measurement, thank you perceive due to the mild irradiation or laptop show difference, so I cannot guarantee pictures and genuine coloration is one hundred pc the same.
