One: Product Function Description:1. lights set contains high efficiency solar panel that absorbs solar energy at daytime, converts it to electricity, stores it in the built-in Lithium battery, and supply power to lights at night. The light control technology makes it by solar power at daytime and light up at night automatically.2. LED indicator light: at daytime when solar panel is being , Blue light will be ON; and at night when lights are working indicator light will be OFF.Two: Product .1. Built in Battery: 3.7V 2200 mAh 18650 Lithium battery 1 pc,2. Solar Panel: 5.5V 1.5W,3. G40 LED Bulbs: 10 PCS,4. Working Current: Less than 150 mA5. Light string length: total 5.5M, 10 LED bulbs, solar panel to cable connecting end 0.2M, connecting end to first bulb 1.22M, distance between each bulb is 0.45M.Three: Use Instruction:1. Connecting the solar panel control box with ground spike and holder;2. Fixing lights at proper place, make sure the solar panel not sheltered, or it will impact the charging of solar power;3. the plastic film on solar panel and press ON\/OFF switch to start the intelligent mode: auto charging at daytime and lighting up at night; press MODE can shift lighting mode;4. Lighting Mode: press MODE once shift to next mode; 4 modes in total:steady ON, slow flash,quick flash and pulsating flash;Four: Product Protecting Function,1.Charging Protect: battery voltage will keep at 4.2-4.25v after charge, and charging will be stopped once voltage is higher, so as to protect charging circuit and battery.2.Discharge Protect: after output and lights stop working, the battery voltage will be 2.8-3.0V, lights can't work at this condition till battery being and voltage is higher than 3.3v.3.Over-current Protect: the output will be stopped immediately once output t is higher than standard.4.Short Circuit Protect: the whole will be off once short circuit occurs, it needs charging and activating again for use.Five: Special Notes1. The conversion efficiency of solar panel will be impacted by sunlight, so the working time of lights will differ due to weather, season and geographical position, it is normal.2. The light can only auto charge and light up at .3. The water resistant feature is designed for rainfall and natural moisture, do not immerse it into water for a long time.4. Do not hit or drop it hard, in case any damage.5. The bottom end of spike is very sharp, DO NOT leave it to children.colour:As shown in colorMaterial:ABS+ glass + solar panelsize:Length: 5.5mPackage Contents:1*Solar charging board10*Decorative light bulbOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
