It’s difficult to see the true color under different light sources in which measurement color deviation intends to occur when performing the color evaluation without a standard light sources. To simulate different light sources to obtain an objective color, color difference and color evaluation, we can put the test specimen into the color viewing booth / color light box, so that it’s easily to see the true color daytime, night, indoor and outdoor, and ensure the color consistency. Color Viewing Booth / Color Light Box can be applied to the industries that need to perform testing color difference as follows: Graphic arts, Photographic, Textile, Dyeing, Packaging, Printing, Leather, Inks, Knitwear, Plastic, Automotive and Ceramics industries etc. Light source: D65 --- International-standard Artificial Daylight Color temperature:6500K Power:18W TL84 --- Applicable to stores in Europe, Japan and China Color temperature:4000K Power:18W F-light ---- Comparison referential light source, Applicable to family/hotel Color temperature:2700K Power:40W UV ---- Ultraviolet light source Wavelength:365nm Power:20W CWF---- Cool White Fluorescent Color temperature:4150K Power:20W
