WILL THE LUMEN REPLACE THE CANDELA?

?DESPLAZA EL LUMEN A LA CANDELA?

IN 1975 IT WAS PROPOSED TO REPLACE THE BASIC PHOTOMETRIC UNIT. REASONS ARE PUT FORWARD FOR THE ADOPTION OF THE LUMEN RATHER THAN THE CANDELA AS A BASIC UNIT SYSTEM SI. THE SELECTION OF THE LUMINOUS INTENSITY AS A FUNDAMENTAL VALUE IS NOT SATISFACTORY AS THE RELATION BETWEEN THE INTENSITY AND OTHER PHOTOMETRIC VALUES IS MATHEMATICALLY INACCURATE. THE DEFINITION OF THE LUMEN FACILITATES THE ESTABLISHMENT OF AN EXACT RELATION BETWEEN THE UNIT OF POWER, THE WATT AND A SPECIFIED MONOCHROMATIC RADIATION. FURTHERMORE A BETTER AGREEMENT BETWEEN INTERNATIONAL PHOTOMETRIC SCALES IS OBTAINED.
