In what units is illumination typically measured?

Kilowatts or amps
Footcandles or lumens
Inches or meters
Decibels or hertz

The correct answer is: Footcandles or lumens

Illumination is commonly measured using footcandles and lumens. Footcandles represent the amount of light that reaches a surface, specifically measuring the intensity of light as it falls on one square foot of area from a uniform source of light. Lumens, on the other hand, describe the total quantity of visible light emitted by a source per unit of time. Together, these units provide a comprehensive understanding of both the intensity and quantity of light in a given space, which are crucial for ensuring optimal lighting conditions in facilities. The other options do not pertain to illumination measurements; power is measured in kilowatts or amps, distance in inches or meters, and sound intensity in decibels or hertz. This highlights the specific nature of footcandles and lumens in the context of light measurement.
