Frequently Asked Questions

What does the unit nox measure?
Nox is a specialized unit that quantifies very low illuminance levels, typically encountered in near-dark conditions such as moonlight or starlight.

How is candela steradian per square meter related to lux?
Candela steradian per square meter is numerically equivalent to lux, measuring luminous flux incident per unit area.

Why convert from nox to candela steradian/sq. meter?
Converting to candela steradian per square meter translates low-level illuminance into a standard photometric unit useful for lighting design and measurement.

Key Terminology

Nox
A historical unit measuring very low illuminance, equal to 0.001 lux, used in near-dark or night-time lighting contexts.
Candela steradian per square meter (cd·sr·m⁻²)
A unit of illuminance equivalent to lux, measuring luminous flux incident on a surface per unit area.
Illuminance
The amount of luminous flux falling on a surface per unit area, commonly measured in lux or equivalent units.
