LED standardized lighting

Graphic & Printing Industry > Visual Color Control Devices
LED lighting is here. Today.

The most accurate, stable, cost effective and highest performance colour critical lighting is now offered by the world’s leading precision viewing light manufacturer, JUST Normlicht.
Whether your application is the research of new materials, matching existing products, or evaluating consistency of production lots, using the best light possible insures accurate visual evaluations.
Our LED viewing light is different.
Not an inferior, non-compliant replacement tube, this patented (Pat. No. US 8,592,748 B2) design is based on our highly successful multi-spectral LED colour viewing light, and is one of the first solution that meets critical ISO and other international standards.
All configurations are packed with features.
Best for critical colour decisions

These LED solutions achieve the best conformance to the CIE D50 and D65 illuminants available today, insuring accurate colour judgements.
With JUST LED technologies using a mix of multiple coloured LEDs, this viewing solution has a more harmonious and complete light spectrum than even our ISO-spec fluorescent lamps.
Coupled with instant-on, infinite dimming, UV on / off, minimal heat output, and no mercury waste – at virtually the same price as the prior technology, the JUST LED luminaire is a cost-effective powerhouse.
Further benefits of the JUST LED technology include :

  • Near perfect simulation of D50, the closest of any commercially available fixture  and substantially exceeding the ISO 3664:2009 specification
  • Continuous dimming without color shifts, ideal for soft proofing
  • Switchable illuminants between D50 (5000 K) and D65 (6500 K) and switchable UV content, allowing identification of optical brightening agents (OBAs)
  • Expected lifetime of 45,000 operating hours (approximately 20x fluorescent  tubes)  
  • Precise inter-luminaire color conditions over time
Colour assessments of substrates and surfaces

Visual colour control with LED-Normlicht can be done regardless of material and texture.
The field of applications are unlimited.
  • Printed Materials
  • Paper & Substrates
  • Plastics
  • Paint, Pigments & Dyes
  • Finishes & Coatings
  • Ceramics & Glass
  • Textiles & Fabrics
  • Wood & Laminates
  • ... just every coloured and fluorescent materials
One LED luminaire.

Multiple advantages.
The new LED proofStation achieves the best conformance to the D50 and D65 illuminants available today, insuring accurate colour judgements.
With JUST LED technologies, a mix of multiple coloured LEDs, and system controls, this viewing solution has a more harmonious and complete light spectrum than even our ISO-spec fluorescent lamps.

The result is natural colour representation – consistent for years – with both D50 and D65 illuminants. Coupled with instant-on, infinite dimming, UV on/off, zero maintenance, reduced power consumption, minimal heat output, no mercury waste – at virtually the same price as the prior technology, the LED proofStation is a cost-effective powerhouse.

  • Switchable light: D50 and D65 according to ISO 3664 and ISO 3668
  • UV content can be enabled or disabled for either illuminant
  • Continuously dimming and USB connection for soft proofing applications
  • No colour shifts while dimming
  • No preheating after turning on
  • 20x longer operating life despite to fluorescent lamps (> 50.000 h)
  • Stable light output during the entire lifespan
  • Annual relamping not required
  • Extremely homogeneous as well as glare- and reflection-free illumination, thanks to Fresnel-type prismatic lens
LED colour viewing stations
Viewing stations provide an installation-ready solution for most 2-D applications.
Accessory sidewalls are available to block ambient light, while storage options provide convenient access to jobs or comparison materials.
They are standing height and available in standard or soft proofing ready configurations, including monitor mounts and pullout keyboard drawers.

Specifications                     
                  
No operating hours meter, no expensive replacement lamps, and no more red warning lamps.
Now you can match colours withour worrying for years.
The LED luminaire combines the high illuminance level of diodes with special Fresnel lenses for optimum homogeneity in illumination and minor reflection behavior.
The continuously high light quality of the LEDs far exceeds the minimum requirements according to ISO 3664:2009 and ISO 3668.
The mix of multiple coloured LEDs generates an even more harmonious and complete light spectrum than that of conventional fluorescent lamps.
