Lumen - Description :
In physics, specifically photometry (optics), the lumen (symbol: lm) is the SI derived unit of luminous flux. It is the amount of light that falls on a unit spherical area at unit distance from a source of one candela. In steradians this is equivalent to the amount of light that falls on a unit solid angle from a light source of one candela. Alternatively, one lumen is the total light produced by an isotropic light source of (1/4p) candelas. A 100 watt incandescent light bulb will output around 1500 lumens.
