A. The visible portion of the output (luminous flux) of lamps used for illumination is expressed in lumens, a measure of the total quantity of visible light emitted by a source. This is possible because the output is measured only in the wavelength response range of the human eye. This response is defined as the photopic luminosity function (Figure 1). Illuminance is the … [Read more...] about Q. Why is there no ‘standard unit’ similar to lighting products for the radiant output of UV lamps?
