Description
CITILED COB Series Amber Model CLU058-1825C4-22AL1K
CITIZEN ELECTRONICS was the first COB manufacturer.
Our long-term advanced knowledge and packaging techniques have enabled us to provide products with excellent reliability and high quality.The Amber-colored COB has been developed as a substitute light source for high-pressure sodium lamps and is intended for use in Street lights, Highway lights, Floodlights and High-masts in airports, seaports and similar places.
The COB series has attained superior color-rendering property while maintaining the high luminous efficacy of a high-pressure sodium lamp. This is also a product with as long a service life as conventional products. The Amber series has the same outer dimensions and LES sizes as those of the conventional products and adopts the chromaticity range of ANSI C78.377 2015.
