Professional Color Evaluation Performance
The JUST Normlicht DLS Color Viewing Light N7 v8 L delivers advanced LED-based color evaluation performance for demanding professional environments. Its optimized control system simplifies color assessment while maintaining precise spectral characteristics, excellent uniformity, and low metamerism values.
D50 and D65 daylight illuminants comply with international viewing standards, while UV-A illumination allows users to identify optical brighteners and fluorescence effects. Additional selectable B-series illuminants provide greater flexibility for evaluating materials under application-specific lighting conditions.
Optimized for Quality Control & Proofing Applications
Designed for professional color-critical workflows, the DLS Color Viewing Light N7 v8 L supports accurate comparison of printed proofs, packaging materials, textiles, coatings, plastics, and manufactured components. Programmable light sequences, stored presets, and customizable illuminant options help maintain consistent evaluation standards across production environments.
The large-format viewing area supports both 2D flat samples and 3D objects made from different materials. Multiple illuminant options provide excellent metamerism detection and improved color communication throughout the production process.
Uniform, Glare-Free LED Illumination
A CAD-based prismatic diffuser system provides highly uniform illumination while minimizing shadows and glare across the entire viewing area. The advanced LED technology delivers stable spectral output, accurate color reproduction, and reliable viewing conditions for professional color evaluation.
The DLS Color Viewing Light N7 v8 L combines precise illumination control with a large-format design, making it ideal for evaluating oversized prints, fabrics, coatings, packaging components, and industrial materials.
