@Simon_Mao Would you look into acquiring Luminus SFT70 in 4000K and 5700K, 95CRI? An unofficial unpublished (thanks @yoelpez for finding me the right word!) datasheet hints at their existence, see this post: New Luminus releases - #38 by yoelpez
Also, would you look into acquiring the SFT42R? It is already available on Kaidomain, and should be a substantial upgrade over the SFT40, with a round die and much better power handling, and a barely larger emitting surface.
