DLS proofStation 20

Specifications

Perfect lighting technology and functional design. No operating hours meter and no expensive replacement lamps. Now you can match colours withour worrying for years. The continuously high light quality of the LEDs far exceeds the minimum requirements according to ISO 3664:2009. The mix of multiple coloured LEDs generates an even more harmonious and complete light spectrum than that of conventional fluorescent lamps. Dimmable proofStations with a practical pull-out keyboard and monitor rail are available for soft proofing applications.
