Description

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 Although it is not commonly used in modern applications, the phot provides a historical reference point for high-intensity lighting measurements, particularly in scientific research and specialized fields.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.

Candela (cd): The SI Unit of Luminous Intensity

The candela is the SI base unit for measuring luminous intensity, representing the power emitted by a light source in a particular direction. Defined by the International System of Units, one candela corresponds to the luminous intensity of a source emitting monochromatic radiation at a frequency of 540 × 10¹² hertz with a radiant intensity of 1/683 watt per steradian. This unit is fundamental in photometry, providing a standardized measure for the brightness of light sources as perceived by the human eye.

In practical applications, the candela is essential for designing lighting systems, ensuring consistent illumination levels in various environments such as workplaces, public spaces, and homes. Understanding and utilizing the candela allows engineers and designers to create lighting solutions that meet specific intensity requirements, enhancing visual comfort and energy efficiency.
