Do you know about the Getian FC40 in 5000K and the Nichia B35AM?
Those are High CRI and Low DUV, as well, especially the FC40. This LED in 5000K is the perfect white, according to me 
and this review: LED test / review - Getian GT-FC40 (≈ 5000K, 90 CRI)
The problem ist, the FC40 is a 12V and the B35AM is a 6V LED. In addition, the B35AM can’t be overdriven much because of it’s missing heatpad.
Again, you will find both at Convoy, but the B35AM also with one or two other manufacturers.
