Semiconductor-based LEDs have reduced electricity consumption for public lighting by a factor of five compared to incandescent bulbs.
Notes on verification
Well-corroborated by DOE and Energy Star data on LED vs incandescent luminous efficacy; the factor-of-five figure is consistent with standard lumens-per-watt comparisons. [tier=silver indep_score=0.77 clusters=2 claim_tier=everyday | framework convergence=partial on luminous efficacy (lumens per watt) comparisons standard in lighting engineering (upstreams: U.S. Department of Energy, Energy Star, general lighting industry efficacy standards) — publishers independent, evidence may not be | kind=empirical eligibility=high (extractor: empirical/medium)]
