We appreciate your feedback PJL. For the lights to work properly they need at least 6-8 hours of direct sunlight. Though the batteries last a year, it is possible the Li-ion 3.7V 18650 batteries need replacement. Please follow the directions in the instruction manual. If you still have issues, you can exchange or return the lights anytime as part of the Member's Mark 100% Satisfaction Guarantee.

Hello Mike, the weather of winter and other nighttime light sources may affect its performance, will get better when spring and Summer. Please ensure there is not any obstructions over the lights and the solar panel receives over 6 hours of direct sunlight every day to re-charge the solar rechargeable battery in each unit to reach maximum output. If the lights still have the same issue, we can replace you the new lights within our guarantee period, please refer the manual book.If you need additional information, please contact us at: wen.chueh@questwood.asia.
