This is a lot of helpful information. I just wanted to comment that what you refer to as "waste heat" from incandescents, we use intentionally (in the winter; we live in Montana) to bring localized warmth to certain areas. My favorite use of this localized warmth is in the dining room. We switch to LEDs in the dining room for the summer, although we don't use the lights in that room too often in the summer, but in the winter, we switch back to incandescent bulbs in the overhead light, which casts soft light and a little pool of extra warmth onto us as we sit at the table eating and playing board games. I'm grateful we don't have to have to the extra heat in the summer, but in the winter, it's a blessing.
