DLS Upgrade System

Specifications

Reliable critical color decisions with excellent spectral characteristics of the new JUST DLS 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.
