Color Difference Comparison Light Box

A color difference light box simulates standard light sources such as daylight and fluorescent light to provide a stable illumination environment. Operators place samples alongside standard color cards for observation to assess color consistency. It is used for color comparison and quality control in industries such as coatings and plastics during production.
Selection
When selecting, consider matching the lightbox size to the sample size and configure commonly used light source types such as D65 and TL84. The inner walls of the box should be neutral gray to avoid reflective interference, and it should feature light source switching and metamerism detection functions. Regular calibration ensures light source stability, and the observation angle should be set at the standard 45°/0° configuration.
