A 400W solar light typically lasts between 8 to 12 hours on a full charge, provided it receives adequate sunlight during the day. The duration of illumination largely depends on the size and capacity of the solar battery, which stores energy from sunlight. That's your baseline expectation. Your solar light's run time depends on how much energy the panel captures during the day versus how much the LED draws at. . Most solar lights last 4–12 hours at night depending on the light type, battery size, and brightness mode. Decorative/path lights often hit 6–10 hours on low/medium, while constant “security-flood bright” output commonly lasts 2–6 hours.
