These include the XYZ tristimulus values, the u\u2019 and v\u2019 color coordinates according to the CIE 1976 standard, and the xy color coordinates according to the CIE 1931 standard. In addition, supplementary color statistics are measured as absolute values and differences. The user can specify the dominant wavelength within the spectrophotometer\u2019s sensitivity range of 360\u2013780 nm, as well as the color density (Pe) and the correlated color temperature (CCT) in kelvins.   <\/p>\n<p>The spectrophotometer can also measure luminance in lux (lx) or foot-candles (fcd) and luminous flux in lumens (lm), as well as display the position of colors in the RGB color space. Thanks to its ergonomic one-handed operation, large display, memory, data interface, and software, the spectrophotometer allows for quick measurements, and the results are reproducible. Test results can be saved using the software. Its specifications make the spectrophotometer ideally suited for classifying and optimizing lighting equipment and conditions in various fields of application.   <\/p>\n<p><iframe loading=\"lazy\" title=\"Color Meter PCE-CRM 40 for light measurement PCE Instruments\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/T0yQoVj4v74?feature=oembed\" frameborder=\"0\" allow=\"accelerometer;
