Dear Friend,How are you!
We make LED by ourself, SMD2835, SMD3528 and SMD5050 are CRI>95, and customize Color Temperature.
Now i recommend a popular led strip, S-shape.
It is much more suitable for corners, as below pictures.SMD5050 S-shape led strip in RGB.
If you are interested in it, please ask me freely.
Best regards
David
