CITIZEN CLU04Q-1211E1-302M2X2

Citizen Electronics is the first COB manufacturer. Leveraging years of knowledge, experience, and advanced packaging technology, it continues to produce high-quality, high-reliability products. The new COB series Version9 maintains the traditional product lineup and package dimensions while achieving high color quality (2-step ellipse) and enhanced drive capability. Furthermore, through the selection of premium materials and optimized production processes, both efficiency and reliability have been improved. These high-reliability, high-efficiency COB light sources contribute to a circular economy by enabling energy savings and reducing carbon emissions.
