Measurements of light density

Light density unit L is candela per square metre (cd/m²), this unit includes the origin of the quantity, that is intensity of the light emitted l per surface angle A, ε angle.
L=I/A*cos( ε).

In brief, light density provides with clarity of a surface which emits light or of a heat source. The Sun has a light density of approx. 1 Mrd. cd/m², discharge lamps about 10.000 cd/m². In the Anglo-Saxon area, the unit foot lambert (ftl) is also used to measure light intensity. This unit is also displayed if you wish so.
1 ftl = (1/π) cd/ft² = 3,426 cd/m².
