We bought these to replace the BT30 bulbs in the recessed glasses in the living room. We black them out every night when we say our candlelight family evening prayers. They seem to work, but not really. At full brightness, the color still doesn't go well with the incandescent bulb. There is a slight color cast reminiscent of mercury lighting, likely due to a low CR index. When they dim, they get warmer, but not warm enough. 2200K doesn't really correspond to the lower limit of incandescent bulbs, which is probably between 1800K and 2000K. Worst of all, in the darkest state they lose their heat completely and the light turns gray (perhaps a very dim 4000K?). There's a sweet spot right in their mid-range where they're decently warm and color reproduction appears good, but that's about it in my experience.
