Candle (International Standard Candle)

Introduction : The international candle was a photometric unit of luminous intensity used before the candela. It represented the light emitted by a standard type of flame under specific conditions, typically a pure spermaceti candle burning at a fixed rate.

History & Origin : Established in the 19th century and internationally recognized in the early 20th century, the international candle served as a practical lighting reference. It was later replaced by the candela due to the need for a more precise and reproducible standard.

Current Use : Today, the international candle is primarily of historical interest. It once formed the foundation for calibrating photometric instruments and measuring lamp brightness, especially in early electric and flame-based lighting systems.

Violle (Platinum Standard Unit)

Introduction : The Violle unit was a high-intensity luminous standard based on a platinum source. Emitting about 20.17 candela, it aimed to offer a more stable and reproducible light reference before the candela was defined.

History & Origin : Proposed in 1884 by French physicist Jules Violle, the unit was based on the luminous intensity from a square centimeter of platinum at its melting point. Though precise, it was difficult to reproduce, limiting its adoption.

Current Use : Mainly used in academic settings and early photometric labs, the Violle unit represented the pursuit of precision in light measurement. It has since been entirely replaced by modern SI-based methods.
