Jar Lid Lights Set - 8-Pack Solar Lid 30 LED Lights and 8 Hooks (jar not included), Lid Diameter Size: 70mm / Insert 2.17" (55mm), Fits Most Regular Mouth Jars. EASY TO USE - Take the film off the solar panel, pull out the plastic, switch to "ON", screw the lid on, and place it in direct sunlight to charge. A built-in light sensor ensures it turns on at dusk and turns off automatically at dawn. Note: Ships only at dusk. If you think it's useless, you can put your gloves on it and you're done. It takes 6 - 8 hours to charge during the day, and about 8 - 12 hours or more to light up. Environmentally friendly and energy saving - 2V 70mA high efficiency solar panel, no external wiring required. A 1.2 V 600mA rechargeable AAA battery is included (each jar has a AAA rechargeable battery in the lid.) Ordinary AAA batteries can be used as backup power if it's not a bright day. WATERPROOF AND DURABLE - The integrated design won't let moisture penetrate the solar panel, and the O-ring seal won't let moisture into the tank. The edge of the lid uses a rust-resistant material instead of a cheap alloy, and you'll find it more durable in wet weather. Versatile - Personalize your jar light however you want. Fill jars with sand, dried flowers, shells, pebbles, seasonal items, and more. Hang it anywhere, such as patio, garden, party, wedding, Christmas backyard outdoor decoration...
