- Color matching cabinet that simulates multiple illumination conditions to provide an objective environment for visual color comparison.
- Includes common light sources such as D65 artificial daylight, TL84, cool fluorescent (CWF), sunset/incandescent A-type, and UV for fluorescence observation.
- Built-in timers record lamp usage time (5 sets) to help manage lamp lifetime; tube replacement is advised after 1000 hours of use.
- Used in textile, printing, plastic, and coating/varnish applications where color appearance must be checked under different lights.

Overview
Cometech QC-701A Super Daylight simulates various illumination environments so users can compare a specimen’s color under standardized light sources.
Because a specimen can look different under different light sources, this cabinet provides multiple common sources (and supports other selectable sources) to help detect metamerism and ensure consistent color decisions.
Configured Light Sources (Standard)
-
- D65 artificial daylight: 6500K, 2 pcs × 18W
-
- TL84 (Europe/Japan): 4000K, 2 pcs × 18W
-
- Cool Fluorescent (US stores): 4200K, 2 pcs × 20W
-
- Sunset / Yellow light (F/A type): 2700K, 4 pcs × 40W
-
- UV lamp (fluorescence): 1 pc × 20W
Key Features
-
- High-frequency electronic activation for fast start-up (reduced waiting time).
-
- 5 independent time records for tracking light usage hours (lamp life reference).
-
- Inner chamber uses light-blocking paint; equidistant lampshades help provide more uniform illumination and reduce hot spots.
