I bought 12 to identify the steps in the garden. (3 boxes). They turn on automatically at night. The gray and rainy days give only 3-4 hours of light before they become dark, but with a few hours of sun during the day, it will remain on even at 4 in the morning (and maybe later I do not know )
Tip: When you take them out of the box, push the button below fort good for 1 second in the dark about whether the light is now on. There will already loaded enough battery to turn it on.
