What is Candlepower?
Candlepower is a historical unit used to quantify the luminous intensity of a light source. Although it has largely been replaced by the candela in the International System of Units (SI), candlepower is still commonly referenced in residential and commercial lighting discussions. It describes how much light is emitted in a particular direction, making it relevant when evaluating focused light beams such as spotlights or directional lighting.
In the electrical and lighting industry, candlepower helps electricians determine the appropriate lighting equipment for areas requiring precise illumination. For instance, outdoor security lights, track lighting, or focused display lighting often rely on specifications that include candlepower to ensure optimal brightness and coverage. Understanding candlepower assists in designing efficient lighting systems that enhance visibility and energy performance in both home and commercial environments.
