Light bulbs or sources that are incandescent were scheduled to be "phased out" several years ago. That was seemingly "put on hold" for reasons which are or aren't clear or scientific.
That is or isn't about to change.
Light-emitting diode (LED) lamps or other "solid-state" technologies are measurably less or more "noisy" or efficient.
Can you guess or predict what's about to happen next?
Backward or "all light is equal".
