Where I work, we still sell rough service bulbs by the case. Some people just like the way they look, and don't want to change.
Women seem to like lighting on the less-harsh yellow side.
Hence the proverbial "candle-lit" restaurant or boudoir.
Same thing with old-time camera films. B&W photographers rarely used the panchromatic (blue-end-sensitive) films for glamor photography unless they used a softening yellow filter on the lens or xenon flash lamps. Orthochrome (red-end-sensitive) film was preferred for glam shots.
Blue-end lamps and films emphasize skin faults.
And a little spit or Vaseline on the lens was often used to soften details. (But don't spit on coated lenses.)
The heavy-duty incandescent lamps would give a more yellowish (candle-like) light.
