What term describes the amount of illumination produced by a source of one candle at a distance of one foot?

• A. Gasket Channel
• B. Graduated Recovery
• C. Foot Candle
• D. Foot Panel

Answer: (C)

Foot-candle is the unit used to express how much light lands on a surface. It means the illumination on a surface that is one square foot in area when the light source is one candle located one foot away. So a single candle at one foot distance delivers about one foot-candle of illumination on that surface (roughly 10.8 lux in metric terms). This standard helps you compare lighting levels in makeup and restorative work, ensuring consistent visibility. The other terms aren’t related to lighting measurement—they refer to unrelated hardware or processes, so they don’t describe how bright a surface is.
