1.The artificial daylight D65 recognized by the International Commission on Illumination (CIE) is used as the basic standard illumination light source. The illuminance range of the light source is 750 to 3200 Luxes. The background color of the light source is medium gray, and its light reflectance must be less than one-third of the incident light.

2.An ultraviolet light source (Ultra-Violet Illuminant, UV) is provided, which is used for detecting items using fluorescent and whitening dyes.

3.A store light source is provided, which can be used for color comparison with other light sources. It can be applied around the clock in various industries such as printing, painting, ink, plastics, and printing and dyeing for operations involving color observation and color matching comparison.

1.A microcomputer is used to control the instantaneous and rapid switching among multiple light sources, avoiding the flickering when turning on like household fluorescent tubes, so as to accurately compare the color differences of goods under different light sources.

2.Accurately record the usage time of each group of lamp tubes. Generally, the lamp tubes need to be replaced after being used for more than 2,000 hours to avoid detection errors caused by the aging of the lamp tubes.

1.It has the metamerism function.

2.It doesn't require preheating, won't flicker, and can ensure rapid and reliable color evaluation.

3.It has low energy consumption, doesn't generate heat (no need for heat dissipation), and has a high luminous efficiency.

4.It is small in size and convenient to use.
