Description
CITILED COB Series Standard Type.,Ra70 Min., Ra80 Min. ModelCLU04Q-1818E1
CITIZEN ELECTRONICS is the first COB manufacturer.
With many years of knowledge, experience, and advanced packaging technology, we continue to produced high quality and highly reliable products.
The new COB series, Version9, while keeping the conventional product lineup and package sizes, achieves both high color quality (2 Step ellipse) and higher driving capability.
In addition, efficacy and reliability are improved by selecting superior materials and optimizing production processes.
Our highly reliable and efficient COB light source contributes to the realization of a circular economy through energy saving and reduction of carbon emissions.
