Yeah. Incandescents were "Deprecated but still available, and not many people worried about it" for about the past 7 years or so, and you could still find them at stores, if you cared. Trump expressed his dislike for LED and CFL lighting, so, of course, the Biden administration went about actually banning sale of incandescents. I expect a robust black market in them for decades to come. The overall energy use numbers really depend on how the bulbs are used - in many areas, lights are mostly used in the winter, when the heat is welcome. Saving energy on lighting and having to burn more natural gas or electricity for heat pumps is perhaps some savings over electricity, but not nearly the 5-6x often cited as "savings." In the summer, when the heat is unwelcome, the sun is up longer, so a well run home won't be using nearly as much artificial light.
