The light produced by a lighthouse varies significantly depending on its design and purpose. Most lighthouses emit light with an intensity ranging from a few thousand to several million candelas. The brightness is often measured in nautical miles, with some lighthouses visible up to 20 or more miles away, helping mariners navigate safely. The specific output can depend on factors like the type of bulb used, the optics of the lens, and the lighthouse's geographic location.
