1It is designed to work continuously for more than 30 days in rainy days (calculated based on 10 hours of work per day). 2With automatic light control function, the lamp will automatically turn on and work in rainy days and at night. Stable work and low cost. 3Using high?efficiency solar chips, the photoelectric conversion efficiency is as high as 19%. No radio frequency, no electromagnetic interference. 4Integrated waterproof design, the light can be immersed in sea water, and the protection level is up to IP68. 5The circuit adopts an advanced charge and discharge management system, which effectively extends the battery life. 6Adapt to all kinds of bad weather, anti?impact, anti?lightning, anti?sun, anti?rain and snow, can resist to typhoon and hail, etc. 7The use of replaceable solar lithium iron phosphate batteries reduces the maintenance cost and difficulty of subsequent maintenance. 8Using marine?grade special plastic materials, it is specially suitable for places such as sea, river, chemical plant, airport and other places with harsh and corrosive environment.
