Product overviewThe LED-based light booth is designed for daily industrial color matching and quality control. It provides switchable CIE D50 (5000 K) and CIE D65 (6500 K) illuminants plus an UV-ONLY (UV-A) option. The Light4Color 400-S integrates a prismatic UV-trans pane and an aluminum housing to deliver uniform, standardized viewing conditions for color assessment.
