Five-star ceiling lights in four sizesThe Yeelight Ceiling Light C Series is the step above the Yeelights A series. It has brought with it the best of smart features and simple control. The significant difference is the new technological dimming curve supported by the C series and some settings. The dimming is not abrupt and the contrast is not as strong at all, which creates a completely different feeling for your eyes.
