About These Units
Gigalumen (Glm)
A gigalumen (Glm) equals 10⁹ lumens. Theoretical scale for astronomical measurements. The Sun outputs approximately 3.8×10²⁸ lumens (38 quadrillion gigalumens). Used only in astrophysical contexts comparing stellar luminosity.
Megalumen (Mlm)
A megalumen (Mlm) equals 1,000,000 lumens. Measures large-scale lighting: stadium lighting system 1-5 Mlm total, lighthouse beacon, and large searchlights. An average sports stadium uses 2-5 megalumens for night games.
