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.

Lambert (L): Unit of Luminance for Diffuse Surfaces

The lambert is a non-SI unit of luminance used to measure the brightness of perfectly diffusing surfaces. One lambert equals 3,183.0988618 candelas per square meter. This unit is primarily utilized in photometry and radiometry to describe the luminance of surfaces that scatter light uniformly in all directions.

Understanding the lambert is important for professionals in fields such as lighting design, astronomy, and material science, where accurate measurements of diffuse reflectance are necessary. While not commonly used in everyday applications, the lambert provides valuable insights into the behavior of light on matte surfaces.
