LED COB strip with dim-to-warm technology?

I am looking for LED strip lighting that is COB (seamless strip - no visible diodes) and has the dim-to-warm technology, preferably 3000K-1800K. Does anyone know of a product like this? I know COB and Dim-to-Warm are fairly new technologies so none of my usual sources have anything like this yet. Hoping it exists somewhere! Thanks!
