DLS Wall Illumination

Specifications

DLS Wall Illumination systems are the professional solution for color critical visual assessments of large format prints, posters, and plots as well as complete layouts of multi-page jobs. All systems contain both CIE D50 and D65 illuminants and conform to the ISO 3664:2009 international viewing standard. These turn-key solutions include luminaires, magnetic wall, mounting hardware, and remote system control panel. Standard system are available in sizes from 4’ (1.2m) to 19’ wide. Custom systems of any size and configuration with additional illuminants and other features are available – just contact us for assistance.
