Lumen is used to quantify the amount of total light energy that a source is putting out in all direction, thus, it refers to luminous output of a light source. Initial lumen refers to the luminosity of a light when it was first turned on; the luminosity is highest at this point.
The lowest possible temperature is absolute zero. However scientists have not reached this temperature, rather they have come very close to absolute zero.
