About These Units
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.
Watt at 555nm (W@555nm)
Watts at 555nm represents the peak luminous efficacy of radiation: exactly 683 lumens per watt at 555nm wavelength (green-yellow light where human eye is most sensitive). This fundamental constant links radiometric (watts) to photometric (lumens) measurements.
