Illuminance Distance Calculator

Calculates the required distance between a light source and a surface based on desired illumination levels. Users input parameters such as target illuminance in lux, the luminous intensity of the light source in candela, and any necessary correction factors like cosine beam angles. The tool then processes these measurements using established optical formulas to provide a precise separation distance. This function allows users to determine how far away a fixture must be mounted to achieve adequate lighting coverage for specific areas or tasks. Professionals in fields such as architectural design, museum display setup, and industrial safety frequently utilize this calculator. Architects use it during the initial planning stages of buildings to ensure optimal internal lighting without over-specifying fixtures.
