Semiconductor-based LEDs have reduced electricity consumption for lighting by a factor of five compared to incandescent bulbs.
Notes on verification
Well-corroborated by DOE and ENERGY STAR data showing LEDs use 75-80% less energy than incandescent bulbs for equivalent light output, consistent with the 'factor of five' claim.
