Revised Standard on Solid-State Lighting Extends Chromaticity Range

In a revision of ANSI C78.377-2017 American National Standard for Electric Lamps—Specifications for the Chromaticity of Solid-State Lighting Products, the ANSI Accredited Standards Committee C78, Electric Lamps, establishes a range of chromaticity for general lighting with solid-state lighting (SSL) products to ensure that product chromaticity can be communicated to consumers. This revision extends the range of color points for general lighting with energy efficient SSL lighting products. It specifies chromaticity regions below the blackbody (Planckian) locus that are suitable for some lighting applications. Annex E Extended Specifications includes recent studies supporting the premise that light sources with chromaticity in the extended correlated color temperature categories are adequate for many applications.
