Paper Abstract

Starting with the well-known nomenclature, symbols and units of thermal radiators and referring to the well-known nomenclature, symbols and units for quantities of visible light one can define a new, quite analogous nomenclature for an arbitrary receptor (detector) with a spectral sensitivity R(λ) . It is pointed out that it might be wise to reject the familiar, however historically grown units in the field of visible light (the candela) and to stick to (light-)watts that match better to the International System of Units (SI) . In an analogous way a system of additional SI-units, named (recepto-)watts is presented. Some examples are given.
