Unit Zlx
Name zettalux
Category Illuminance
Details A zeptolux (zlx) is an extremely small unit of illuminance in the International System of Units (SI). Illuminance is a measure of the amount of luminous flux (light energy) incident on a surface per unit area. It is typically used in the field of photometry to describe the intensity of light experienced at a specific point or surface.

The lux (lx) is the standard SI unit of illuminance, representing one lumen per square meter (lm/m²). The prefix "zepto" (z) is an SI prefix that represents a factor of 10^-21, meaning a zeptolux is equal to 10^-21 lux.

In practical terms, the zeptolux is an enormously small unit that would rarely, if ever, be encountered in real-world applications. For comparison, a typical indoor home or office environment might have an illuminance level around 100-500 lux, while direct sunlight can have an illuminance level over 100,000 lux. Using the zeptolux in these situations would be impractical due to the extremely small value it represents.
