COB lights have led lighting technology that uses several led chips that are directly mounted to a circuit board to create a single module. Because of the high density of the said chips made possible by this design, the light output is brighter and more even than with conventional led lights. Additionally, COB lights have a greater colour rendering index (CRI), making them better able to reproduce colours than conventional lights. They are also more effective at converting energy into light, last longer, and require less energy. Commercial lighting, outdoor lighting, and indoor house illumination are just a few of the popular uses for these lights.
