About Lumens
The lumen (lm) is the SI derived unit of luminous flux, equal to 1 cd·sr. A standard wax candle emits approximately 12 lm total; a 40 W incandescent bulb about 450 lm; the common 800 lm LED lamp is the direct replacement for a 60 W incandescent. Defined since 2019 SI by fixing K_cd = 683 lm/W at 540 THz. 1 lm = 1 cd·sr.
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.
