The devices are categorized for luminous intensity. The intensity category is designated by a letter on the side of the package. 2. Color coordinates are based on the CIE 1931 Chromaticity Coordinates. See Figure 10. 3. Test current for each color is applied to individual colors per color combination. Figure 3.
