This is the SI unit for luminous intensity. The definition relates to blackbody radiation emitted at a certain temperature for a certain material (so I guess it ISN'T blackbody!), platinum, I think.
Except... I don't understand the necessity for the introduction of this unit.
Isn't intensity equal to power per area? Or is this something totally different?
