Semiconductor-based LEDs have reduced electricity consumption for lighting by a factor of five compared to incandescent bulbs.
Notes on verification
Confirmed by CNRS source and corroborated by French parliamentary/ADEME data and industry sources; exact multiplier varies (4x-7x) depending on bulb comparison, but 'factor of five' is a commonly cited, reasonable rounded figure.
