Our lights work best with 2–3 hours of direct sunlight. Without this, all of our solar powered lights are equipped with our innovative Solar Lighting Controller (SLC). The SLC in each light is self-learning which allows the lights to predicatively adapt to their surroundings, providing a level of lighting performance and reliability unmatched in other solar products. A brief conversation will determine if our SLC can provide the lighting levels you require. Please call us at 1-844-279-8754.
