Details for Lumen per Steradian (Candela Equivalent)
Introduction : Lumen per steradian is the formal definition of the candela, representing the amount of luminous flux in a specific direction. Since 1 candela = 1 lumen/steradian, it offers a geometrical understanding of directional brightness.
History & Origin : This definition came with the formal adoption of the candela by the CGPM in 1948. It replaced older flame-based references with a quantifiable measure of light intensity rooted in solid-angle physics.
Current Use : Used in precise photometric calculations, especially in physics and engineering. It helps quantify directional luminous output from point sources like LEDs, lasers, and optical instruments.
Details for Candlepower (Old UK Definition)
Introduction : Old candlepower, used in the UK, represented luminous intensity based on a standardized flame source. Slightly brighter than the international candle, it equaled approximately 1.02 candela.
History & Origin : Before SI adoption, candlepower was a widely used term in the UK and US. The 'old' version was tied to traditional British standards like whale oil lamps, differing subtly from continental equivalents.
Current Use : This unit was common in lighting design, ship lamps, and lighthouses. Though no longer in use, many older lighting records and specifications still reference old-style candlepower values.
