ANSI C78.377:2017 PDF Download

ANSI C78.377-2017, also known as the American National Standard for Electric Lamps - Specifications for the Chromaticity of Solid-State Lighting (SSL) Products, provides guidelines for the chromaticity of solid-state lighting (SSL) products used for general lighting purposes. This standard aims to establish a range of chromaticities that are suitable for SSL products and ensures that consumers can easily understand and compare the white light chromaticities of different products.

The standard specifically applies to SSL products that are LED-based and incorporate control electronics and heat sinks. It outlines the recommended range of chromaticities for these products, which helps to ensure that the white light emitted by SSL products closely matches the desired color temperature and hue.
