Solar lighting should be evaluated for its actual installation environment. Ask suppliers for the photovoltaic module rating, battery chemistry and capacity, operating modes, expected autonomy and ingress protection rating.
For street and exterior lighting, confirm mounting dimensions, beam distribution and installation height. Request comparable test conditions rather than relying solely on advertised lumen figures.
Sample requests should identify intended destination, application and quantity. Final specifications, certification needs and shipping arrangements should be confirmed in writing before an order.
