About Megacandelas
The megacandela (Mcd) equals 10⁶ cd. The range for powerful searchlights and lighthouse optics: a large maritime lighthouse lens emits 1-10 Mcd; military anti-aircraft searchlights of WWII reached 1-2 Mcd; modern LED lighthouse arrays 2-5 Mcd. 1 Mcd = 10⁶ 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.
