Light booth and Luminaire for color critical appraisals

Visual color evaluation in a light booth

Uniform color is directly associated with high quality and influences our purchasing decision. This is especially true for multi-component products consisting of different materials being produced by different suppliers. The human eye is often the final judge for approving a new design. Therefore, the visual inspection conditions need to be standardized to guarantee repeatable visual results. The most important color match is under natural daylight. The CIE defined several standard daylight illuminants with D65 being the most important one. The lamps used in a light booth must simulate CIE D65 as close as possible. Until now, fluorescent tubes were used to simulate D65. A new unique lighting setup is now able to achieve class A quality by simulating CIE D65 with a smart combination of filtered halogen lamps and LEDs.
