DLS Upgrade System

Specifications

Reliable critical color decisions with excellent spectral characteristics of the new JUST LED moduLight. This luminaire has a more harmonious and complete light spectrum than even our ISO-spec fluorescent lamps. The result is natural color representation – consistent for years, without annual relamping!
The LED Upgrade System is available for a variety of color matching stations. The DLS Upgrade System consists of the original JUST DLS moduLight lamp including mounting. With a few simple steps you can upgrade your existing color proofing station.

Switchable light: D50 and D65 according to ISO 3664 and ISO 3668
UV content can be enabled or disabled for either illuminant regarding new and old ISO standard
UV-ONLY: UV-A for the detection of optical brighteners
Continuously dimming and USB connection for soft proofing applications
No color shifts while dimming
No preheating after turning on
Annual relamping not required
20x longer operating life despite to fluorescent lamps (> 50.000 h)
Stable light output during the entire lifespan
