Description

Candlepower (cp): Traditional Measure of Luminous Intensity

Candlepower is an older unit of luminous intensity, historically defined as the light emitted by a standard candle. While it has been largely replaced by the candela in the International System of Units, candlepower is still used colloquially to describe the brightness of flashlights, spotlights, and other directional light sources. One candlepower is approximately equal to one candela.

Despite its obsolescence in scientific contexts, understanding candlepower remains useful for interpreting product specifications and consumer information, especially in industries where traditional units persist. Recognizing the equivalence between candlepower and candela facilitates accurate comparisons and informed decisions when selecting lighting equipment.

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 Although it is not commonly used in modern applications, the phot provides a historical reference point for high-intensity lighting measurements, particularly in scientific research and specialized fields.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