Upgraded Solar Lights- We have increased the battery capacity, which means that the lights will last longer than before. They charge for 4-6 hours in full sunlight and light for 6-8 hours. Automatic Turn on/ off- They absorb sunlight so will automatically charge all day in the sun and turn on at night. Require no electricity or wires, no need to worry about dead batteries. Easy to Assemble- Turn on the switch at the base of the top, then install each parts together and insert each light into the ground. ( Please do remember to switch on the lights before first use) IP65 Waterproof- These solar lights are made with stainless steel and are water resistant. There are 2 holes under each lampshade to let water out, you never need to worry about rainy or snowy days.
