Selected fluorescent lights for color vision testing

1 February 1979


Results on color vision tests were compared using the Macbeth Easel Lamp and three fluorescent lamps each as the source of illumination . Tests used were the HRR Pseudoisochromatic Plates, the Davidson and Hemmendinger Color Rule, the Farnsworth D-15, and Farnsworth 100-Hue. All three fluorescent lamps appeared to be adequate replacements for the detection and classification of color anomalies with the tests used, with the possible exception of the D & H Color Rule . On the Color Rule, Ultralume and Cool-White showed poor differentiations between protanomalous individuals and normals. For careful quantifications of color anomalies, none of the three fluorescent lights gave quite the same results as the Macbeth Lamp. The Vitalite appeared most similar to the Macbeth overall, next the Ultralume 5000, and lastly the Cool-White.
