Replacement light unit. *The charging time and working time of the solar light varies with sunlight intensity. In winter, solar light receives less energy from sunlight, so it is normal to have a lower brightness and shorter working time at night. Illuminance is a measure of how much luminous flux is spread over a given area. One can think of luminous flux (with the unit lumen) as a measure of the total "amount" of visible light present, and the illuminance as a measure of the intensity of illumination on a surface. A given amount of light will illuminate a surface more dimly if it is spread over a larger area, so illuminance is inversely proportional to area when the luminous flux is held constant.
