if I'm not too late, I really like this brand:

Those are 50w replacements though so you'd need a dimmer. They have 4k and 5k color (white and whiter) so you can choose but they are high CRI (90+) or color reproducibility.

I also read good things about G7 Brand bulbs and like my torchstar brand bulbs, they both probably have GU10's
