Intensity Calculations
One of the most important considerations is the effective intensity produced by a lantern (candela). This is how the nautical mile range is determined. Effective intensity is measured on a "light range" and Tideland Signal is one of the only AtoN companies that have their own range, meeting IALA guidelines.
