The end of an era is coming for incandescent light bulbs. The Department of Energy put two new rules on the books this week banning the production of these energy-sucking light sources in 2023, at which time manufacturers will be able to sell only energy-efficient light bulbs.Apr 28, 2022
Why are incandescent bulbs banned?
Why are incandescent light bulbs banned? The traditional incandescent light bulb is being phased out in the United States because it’s very inefficient. Less than 10% of the energy used by an incandescent light bulb goes to producing light; most of the energy is wasted as heat. What are the advantages and disadvantages is incandescent?
Are incandescent bulbs banned?
There is no such thing as an incandescent light bulb ban in the United States. In fact, on the very same day that the 60-watt incandescent light bulb disappears, you'll be able to buy a 43-watt incandescent light bulb to take its place. Or a 72-watt incandescent bulb. Additionally, why can I still buy incandescent light bulbs?
Is there an incandescent light bulb ban?
While incandescent light bulbs haven’t been banned per se in the United States, they have recently been “phased out”—which is just a more polite way of saying they’ve been gradually replaced with more energy efficient alternatives. The same goes for the European Union, Canada, and China.
Are halogen light bulbs hotter than incandescent?
Yes, halogen bulbs get hotter than incandescent. You won’t be exaggerating if you say between a halogen bulb and incandescent the temperature difference is twice or more. For the halogen bulbs, you can blame the design, materials used, and most of all the halogen cycle for getting heated.
Overview
Regional developments
Botswana has an exchange program distributing CFL bulbs. Of the members of ECOWAS, Cape Verde, Guinea, Mali, Nigeria, Benin and Togo have had exchange programs to replace incandescent bulbs with energy efficient versions. Ghana banned incandescent bulbs in 2008 and Senegal has banned the manufacture and import.
Alternatives to incandescent bulbs
The light from an incandescent source is similar in character to that from a Planckian "black body" in spectral distribution, that is, the bulb, as the filament heats up, produces light from wavelengths throughout the visible spectrum. Alternative light sources use phosphors or combinations of mono-chromatic LEDs (red, blue, and green) to produce "white" light, giving significantly irregular spectral distributions that can create color casts in photography and differences of color matchi…
Public opposition
The phase out has been referred to as "light bulb socialism". The consumer preference for light bulbs in the EU was for incandescent bulbs, with many complaining at the time of the regulation's adoption about what was described as the ugliness or the cold, flat, unnatural, dull light emanating from CFLs. Objection has also been raised to being forced to adopt CFLs. Improvements in LED technology allow these bulbs to more closely match the color temperature of …

Incandescent light bulbs are gradually being phased out in favor of more energy-efficient options such as CFLs (compact fluorescent lamps) and LEDs (light-emitting diodes).
