Alpine Corporation Solar Pathway Stake with Light -Tray Pack of 9. The Solar Pathway Stake with Light, a set of 9 solar-powered lights designed to brighten up pathways and outdoor spaces. These stakes are perfect for adding a warm and inviting glow to a garden or landscape. Each stake has a dimension of 4"L x 4"W x 17"H and features a single warm white LED with a brightness of 5lm. The solar panel, measuring 40x40mm, has a capacity of 2V and 80ma and is made of durable polysilicon. It efficiently captures solar energy during the day to charge the built-in 1.2V AA Ni-CD 500mAh rechargeable and replaceable battery. There is no switch on these solar pathway stakes.

Once the insulating sheet is removed, the lights will automatically turn on at dusk and provide illumination for 6-8 hours after being fully charged during the day.
