Description

Lux Second (lx·s): Unit of Luminous Exposure

The lux second is a unit of luminous exposure that quantifies the cumulative amount of light (illuminance) received by a surface over a specific duration. It is derived by multiplying illuminance, measured in lux, by the time in seconds. This metric is vital in scientific research and industries where both the intensity and duration of light exposure matter, such as photography, photobiology, and lighting engineering.

For photographers and lighting designers, understanding lux seconds helps determine the proper lighting duration for optimal exposure. In biological research, it aids in quantifying light therapy doses or assessing plant light exposure in controlled environments. This unit bridges the gap between instantaneous light measurement and long-term exposure, supporting better accuracy in light-related assessments.

Phot (ph): CGS Unit of Illuminance

The phot is a unit of illuminance in the centimeter-gram-second (CGS) system, where one phot equals 10,000 lux. Although it is not commonly used in modern applications, the phot provides a historical reference point for high-intensity lighting measurements, particularly in scientific research and specialized fields.

While the SI unit lux has largely supplanted the phot, familiarity with this unit can be beneficial when interpreting older scientific literature or working within specific contexts where CGS units are still in use. Recognizing the conversion between phot and lux ensures accurate understanding and communication of illuminance values.
