Most solar lights have a run time of anything between 6 hours to 12 hours. Certain exceptional products (we’ve mentioned some of them on this list) can last for up to 18 hours, though this is not common.
The run time of a solar flagpole light depends on a multitude of factors. The amount of sunlight in a day, the brightness mode selected, the health of the battery, etc., all determine the runtime. We recommend positioning your flagpole light in a way that it receives maximum sunlight, especially during peak noon.
We’ve also noticed that products with sloped panels can absorb sunlight most effectively.
