About Violle
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 Gigacandelas
The gigacandela (Gcd) equals 10⁹ cd. The scale for extremely powerful directed beams and for astrophysical luminous intensity comparisons. A nuclear fireball at peak emission approaches this range; high-power pulsed laser outputs in the visible spectrum can reach Gcd-level peak intensity in the beam axis. 1 Gcd = 10⁹ cd.
