What is a centimeter-candle?

A centimeter-candle is an obsolete unit of illuminance equal to the illumination at one centimetre from a one candle point light source. It has been replaced by the lux in modern measurement.

Where is lumen per square foot commonly used?

Lumen per square foot is often used in lighting practice for offices, classrooms, retail spaces, photography, film lighting, horticulture, and museums.
