Lumen (lm) is a unit in the category of Luminous flux. It is also known as lumens. This unit is commonly used in the SI unit system. Lumen (lm) has a dimension of JW where J is luminous intensity. It essentially the same as the corresponding standard SI unit cd-sr.
Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).
Other units in the category of Luminous flux include Candlepower (spherical).
