The DLS Color Viewing Light gives you a viewing booth that offers high-quality simulation of a wide variety of illuminants in a larger colour space than sRGB. Use the matching software to define the illuminants of relevance for you. The multispectral LED light source realizes them perfectly. The unique, patented LED calibration method guarantees permanently consistent light conditions.

With a correlated colour temperature (CCT) of 6500 K, D65 corresponds to "average daylight from the northern sky" and is the reference illuminant in DIN 6173-2 "Colour matching" and a referenced illuminant in ASTM D1729. Its spectral energy distribution between 300 and 780 nm is described in DIN 5033 at increments of 5 nm.

Any lamp designed to simulate D65 must comply with standard ISO 3668 "Visual comparison of the colour of paints". The standard describes all the parameters required to ensure standard-compliant colour comparisons, such as standards presentation, viewing and ambient conditions. The illuminance level defined in this standard is between 1000 and 4000 lux, this wide range being due to the diversity of different applications. JUST viewing booths and luminaires achieve an illuminance of 2000 lux as standard, with optional brightness controls on soft proofing models.
