Correct lighting conditions are essential for accurate color comparison. Northern Daylight (or Southern Daylight in the southern hemisphere) is preferred because it maintains a more consistent color temperature over the course of the day, unlike direct sunlight where the color temperature varies according to the time of day.However, because ideal lighting conditions are not always available naturally, Orbeco-Hellige has developed a line of lighting units to provide a standardized, consistent light source that simulates Northern Daylight.

This means that reliable test results can be obtained at all times, and under all ambient light conditions.Orbeco-Hellige light sources provide a constant and stable light using a tungsten halogen lamp and a calibrated color temperature correction filter. This guarantees correct lighting conditions 24 hours a day. We recommend the use of a light source when visually matching colors for optimal results.
