CITILED COB Series Blue Model CLU048-1212C4-B455-XX
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. We succeeded in developing the high- power blue light COB, with in excess of 400W power, by adopting our specific heat-release technique.
The blue-colored COB is intended for applications such as lighting for swimming pools, landscapes and security. This is also a product with as long a service life as conventional products. The outer dimensions and LES sizes are the same as those of the conventional products. The optical characteristics values were obtained at Tc=25C.
