About Gigalumens

The gigalumen (Glm) equals 10⁹ lm. The scale for very large lighting installations and for theoretical comparisons: a large airport apron illuminated to 30 lx over 1 km² would require approximately 30 Glm of total installed luminous flux. The full-disk luminous flux of the Sun is approximately 3.6 × 10²⁸ lm. 1 Glm = 10⁹ lm.

About Megalumens

The megalumen (Mlm) equals 10⁶ lm. The output range for high-bay industrial luminaires and stadium floodlights: a 1 000 W high-pressure sodium lamp array produces approximately 1.1 Mlm; full LED stadium lighting systems reach 1-10 Mlm; maritime lighthouse optics emit in the low-megalumen range. 1 Mlm = 10⁶ lm.
