Re: Meeting of the minds Not knowing what Don will say.... yet .... I submit that if the readings per square centimeter are identical then the quantity AND the density are also the same. What you are saying would apply to "UV flux" ...the crazy units Cosmedico uses to measure lamp output in "watts of UV". Then the density of LP flux is less than the density of HP flux. But meters don't measure flux.. they measure output per unit area. So do spectralradiometers. . |
