[0002] Colorfastness rating light boxes are typically equipped with standard light sources, such as D65 light sources, which can simulate sunlight exposure conditions to conduct sunlight colorfastness tests. It measures the degree of fading of textiles under sunlight exposure and is one of the important indicators for evaluating textile quality. For textiles used outdoors, such as parasols and outdoor furniture fabrics, light fastness testing is particularly important because it directly affects the product's lifespan and appearance.
