Solar panels: use polysilicon solar panels, the conversion rate is up to 23% . Light energy can be quickly converted into electrical energy, and lifetime can reach 20 years.

Lithium battery: 500-1000 times cycles of charge and discharge, overcharge and overdischarge protection. Easy to replace the battery, you will not need to replace the whole light, you only need to unscrews 4 screws to replace the battery and make the possibility of the lifetime of the light to be 8-10 years.

Angle: adjustable multiple installation angles, adapt to different environmental needs.

Intelligent sensor: 18 hours full brightness and 36 hours in DIM mode with PIR sensor, automatically adjusted backup days. Save power, to ensure the effective lighting capabilities of the lamp.  Back up time: 3 nights.

Lens: special lens with large angle light distribution. Make the possibility of pole distance larger. Reduce the number of lights and poles used in the project
