Incandescent Lamps
Federal efficiency rules took most standard incandescent household bulbs off the market in 2023. What remains is mostly specialty lamps the rules exempt: appliance, tubular, sign and some decorative lamps. Match the shape code (A, G, T, S), base and voltage printed on the old lamp. Many incandescent lamps do not meet California Title 20, so some cannot ship to California addresses. For general lighting, an LED A19 uses about 85 percent less energy.
