I didn't love the author's suggestion of Edison bulbs, but maybe I am missing something amazing about them that makes up for the fact that they use ~10x the energy of low color temperature (e.g. 2500K) LEDs? I guess it seems online that "Edison bulb" can refer to form factor rather than incandescent?
