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.

About Millicandelas

The millicandela (mcd) equals 10⁻³ cd. The most common unit in LED datasheets: a standard 3 mm through-hole LED has 5-500 mcd at 20 mA; a high-efficiency indicator LED 500-2 000 mcd; signal LEDs for visible-range indicators typically 10-200 mcd. The IEC standard range for low-current indicators. 1 mcd = 10⁻³ cd.
