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.

Stilb (sb): CGS Unit of Luminance

The stilb is a unit of luminance in the CGS system, where one stilb equals 10,000 candelas per square meter. Although it is not commonly used in contemporary applications, the stilb serves as a historical unit for measuring high-intensity luminance, particularly in scientific research and specialized fields.

While the SI unit cd/m² has largely replaced the stilb, knowledge of this unit is useful when interpreting older scientific data or working within specific contexts that utilize CGS units. Understanding the conversion between stilb and cd/m² ensures accurate communication and analysis of luminance measurements.
