EnglishYes, there are differences in the light transmission distance of marine navigation signal lights. The light transmission distance, or range, of a marine signal light is determined by several factors, including the power of the light source, the design of the optical system, and atmospheric conditions.
The International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) sets standards for the light characteristics of marine navigation signal lights, including their range. According to IALA, the range of a marine signal light is the maximum distance at which the light can be seen in clear weather conditions, with a light background and unobstructed line of sight.Some marine signal lights may have longer ranges depending on their design and the conditions in which they are operating.
