The violle (Vl) ≈ 20.17 cd is the first photometric unit not based on a flame source, proposed by Jules Violle in 1881 and adopted by the CGS system. Defined as the luminous intensity of 1 cm² of platinum at its solidification point (1 768 °C). Used historically in French and international photometry before 1948. 1 Vl ≈ 20.17 cd.
About Candelas
The candela (cd) is the SI base unit of luminous intensity. A standard wax candle emits ~1 cd; a 60 W incandescent bulb ~60 cd (assuming Lambertian emission); a 1 W white power LED ~100 cd peak in a 5° beam. Defined since 2019 by fixing K_cd = 683 lm/W at 540 THz. 1 cd = 1 lm/sr.
