Contrary to popular belief, lighting is not a vague or purely subjective concept. Illumination can be measured and quantified with precision. Just as an engineer can assess the slipperiness of a surface through friction measurements, they can also evaluate the lighting conditions of an area using established metrics. Building codes, life safety codes, and industry standards specify detailed illuminance levels that vary depending on a building’s function and location.

For example, stairwells often require higher levels of illumination than other areas, while routes of egress may be subject to strict lighting standards. Certain public spaces, such as movie theaters, may be granted exemptions due to their unique usage. Outdoor spaces like parking lots may not always fall under specific codes, but relevant standards still exist and should be followed.

Importantly, measuring average illuminance alone is not always sufficient—an area may meet overall standards while still having spots that fall below acceptable levels. Additionally, illumination gradients must be considered; abrupt transitions from bright to dim lighting can create hazards, even when overall light levels are technically compliant.
