Our garden solar lights can be located in shade or sun. They are suitable outdoor solar lights for trees or shadows. Each light has a number indicating the type of shade where it can be used. The higher the number the dimmer the shade where it can operate.
This sketch illustrates Category 1 shade which has a shadow and a clear view of the sky above the solar light. The shadow is caused by a large object like as a tree or building. The ambient light for recharging a battery in Category 1 is much weaker than direct sunlight. Ordinary solar lights cannot function normally in Category 1 shade. A Shade Solar Light made for Category 1 works in Category 1 shade or direct sunlight.
There is less ambient light in Category 2 than Category 1. The sky-view is blocked as illustrated by this sketch. Ordinary solar lights may suffer battery failure in Category 2. A Shade Solar Light made for Category 2 can operate in shade categories 1 or 2, or in direct sunlight.
There is less ambient light in Category 3 than Categories 1 or 2. A forest can have Category 3 shade in summer and direct sunlight in winter (after the leaves fall). An ordinary solar light is useless in Category 3. A Shade Solar Light made for Category 3 can operate in categories 1, 2, or 3, or in direct sunlight.
Do solar lights need to be in direct sunlight? No, Shade Solar Lights operate in shade categories 1, 2, or 3, or direct sunlight.
Please note that clouds may add 1 to 2 points to a shade category, changing Category 1 to Category 2 or 3 on a cloudy day, for example. Tree vector created by Freepik
