They finally made the switch! (http://www.nichia.co.jp/en/product/led_sp_optisolis.html) Maybe Prof. Nakamura at Soraa was right to say that violet pump leds will eventually take over blue pump ones. Their new series is named Optisolis. From the datasheet, it has a peak at 420nm, does not suffer from cyan gap, comes in neutral and warm, has respectable 120+lm/W efficacy. I guess exciting times are ahead for high CRI snobs, very soon we may see high power Nichia leds that have better color rendering than R9080 219Bs and yet higher efficacy than Yuji leds.
