The Cooke Corporation has been manufacturing and distributing light measuring equipment since 1986. Our cal-LIGHT 400 Series of Digital Lightmeters, cal-COLOR 400 Colormeter, and cal-SPOT 401 Spot Photometer are used world-wide wherever accurate readings are required. COOKE prides itself on having our own calibration facility, and is therefore able to individually calibrate each meter to NIST standards. When accuracy is required, people trust COOKE meters.
