In recent years, with the continuous advancement of global energy conservation and emission reduction policies, incandescent light bulbs have gradually withdrawn from the mainstream lighting market.
However, the question of whether incandescent light bulbs are making a comeback has once again sparked discussion among the media, industry, and consumers. Policy adjustments in some countries, consumer nostalgia, and the development of new technologies seem to have brought incandescent lamps back into the public eye.
So, will incandescent light bulbs really come back again? Let’s break it down in this blog.
As the earliest lighting technology to be widely used for over a century, incandescent bulbs have made a huge contribution to the development of modern society. However, their inherent problems of high energy consumption and low efficiency have become increasingly prominent under the pressure of the contemporary energy structure.
It is the biggest reason. Incandescent bulbs convert 90% of the electrical energy into heat, with less than 10% actually turning into light, which is an extreme waste of energy.
The lifespan of an incandescent bulb is generally only about 1,000 hours. The filament evaporates quickly at high temperatures and is prone to burning out.
Due to the low efficiency of incandescent bulbs, more electricity is needed to meet the lighting requirements, resulting in more carbon emissions.
The U.S. Department of Energy points out that LED bulbs are far more energy efficient than incandescent bulbs and are the main alternative.
Despite these bans, debates around consumer choice and lighting quality never really disappeared.
Speaking of why the government intervenes instead of letting the market decide, it was driven by some economic and environmental concepts.
● Externality Issues: if someone used incandescent bulbs, they paid their power bill, but they didn't pay for the environmental damage.
● Market Failures and Information Gaps: In reality, there are split incentives and upfront costs suppressing the desire to buy.
● Scaling the Technology: If lighting companies knew incandescents were going away, they could safely invest billions into LED research and mass production.
Although the free market usually rewards efficiency, the government intervenes because the transition to energy-efficient lighting is far slower than the requirements of climate targets.
The inefficiency of incandescent light bulbs is particularly prominent against the backdrop of global energy shortages. With increasing awareness of energy conservation and environmental protection, many countries and regions have begun to take measures.
Below are the policies of the United States and Canada regarding the incandescent light bulb ban:
Here is the timeline of how the rules changed across the different administrations:
1. Initial Federal Efficiency Legislation (2007)
In 2007, the Energy Independence and Security Act, signed by Bush, set minimum energy efficiency standards for phasing out incandescent light bulbs. If the Department of Energy fails to set sufficiently high standards by 2020, a strict minimum standard of 45 lumens per watt will be automatically enforced, effectively banning traditional incandescent bulbs.
2. Regulatory Scope Expansion (2009–2017)
During this period, the Department of Energy expanded the definition of general lighting fixtures to include specially shaped light bulbs in energy efficiency regulations. This aimed to close regulatory loopholes and more thoroughly phase out inefficient light bulbs.
3. Regulatory Revision and Scope Adjustment (2017–2021)
Subsequent regulatory revisions revised the expansion of light bulb energy efficiency standards. The updated regulations resulted in the standards not taking effect automatically in 2020, allowing certain specialty incandescent bulbs to remain on the market.
4. Reinforcement and Standard Implementation (2021–2024)
Federal regulators have restored the energy efficiency standard of 45 lumens per watt and expanded its application. The ban, which took effect in August 2023, has almost completely phased out traditional incandescent bulbs and plans to implement a higher standard of 120 lumens per watt in 2028.
5. Current Regulatory Framework (2025–Present)
The energy efficiency standards for lighting products set by the federal government, including those for incandescent bulbs, are regularly reviewed and revised in accordance with regulatory procedures. These reviews will assess market conditions, technological developments and consumer considerations.
Canada began phasing in incandescent lighting restrictions in 2007, with provinces such as Nova Scotia, Ontario, and British Columbia introducing plans between 2007 and 2011. A federal ban on inefficient bulbs, initially set for 2012, took effect on January 1, 2014, covering 75W and 100W bulbs, and expanded in 2015 to 40W and 60W models, excluding specialty lamps. Retailers could sell existing stock. Programs like ENERGY STAR supported higher efficiency standards. The policy targets low-efficiency products rather than banning all incandescent technology.
With continuous technological advancements, LED bulbs are gradually becoming a replacement for incandescent bulbs. Compared to incandescent bulbs, LED bulbs offer significant energy-saving advantages.
● High Efficiency: LEDs can convert more electrical energy into light rather than heat, saving about 75% more energy than incandescent light bulbs. This is the core driving force for policy promotion of technological upgrading.
● Cost over time: LEDs have an average lifespan of 25,000 to 50,000 hours, which significantly reduces replacement costs and electricity bills in the long run.
● Improved Quality: Modern leds have overcome their early shortcomings and can provide high CRI, warm color temperature, and flicker-free light, meeting the requirements of comfortable lighting.
● Policy Logic: The standard aims to accelerate the market’s natural transition toward a more efficient and more economical long‑term technology. It also seeks to ensure this mature-quality technology achieves a balance between energy conservation and user experience.
Policy promotion of LED means that if enterprises continue to purchase or sell inefficient traditional lamps, they may face compliance risks of not meeting energy efficiency regulations. Also, when making purchases, enterprises need to give priority to LED products that meet the latest energy efficiency standards to ensure the stability of the supply chain and policy adaptation.
In the long term, the adoption of LEDs helps enterprises to make early plans for the future trend of energy efficiency upgrades and reduce the renovation costs caused by policy changes in the later stage. At the same time, timely switching to LED products can reduce the inventory risk of traditional lamps being overstocked or unsalable due to policy restrictions.
So why do a lot of people want incandescent bulbs to come back? It is an interesting mix of nostalgia, specialized technology, and a bit of regulatory flexibility in energy regulations. While the world has largely moved to LEDs for general lighting, the classic glowing filament hasn't completely flickered out.
Some designers and homeowners often find LEDs more clinical. Many people still prefer incandescent bulbs emitting warm light. The warm light of incandescent bulbs can make the home environment more cozy and relaxing, so they remain popular in certain settings with strong emotional atmospheres, such as bedrooms, living rooms, and cafes.
Also, some LED systems, particularly lower-quality products or poorly designed dimming circuits, may exhibit flicker under specific conditions. Incandescent bulbs have almost no perceptible flicker.
Taken together, these factors help explain why incandescent bulbs continue to attract attention.
Here are the primary discussion currently active:
1. Health and Blue Light Discussions
Some groups argue that incandescent bulbs should remain available for biological and health-related reasons. Spectrum Alliance (UK) and various "Healthy Lighting" advocates have petitioned governments, demanding that people with light-sensitive conditions be allowed to use incandescent lamps. The continuous spectrum of incandescent lamps is generally regarded as more natural.
2. Political and Regulatory Debate
After the 2024 election, the new government began to re-evaluate the Department of Energy's 2023 ban on general incandescent bulbs. This measure is intended to enhance market flexibility by allowing consumer choice and reducing regulatory constraints, enabling market dynamics to play a greater role in determining technological transitions. However, others emphasize that efficiency standards are designed to reduce national energy consumption and long-term costs.
3. Experimental High-Efficiency Incandescent Research
Researchers at MIT developed a way to surround a tungsten filament with a special crystal structure that captures "wasted" heat and reflects it back to the filament to be re-emitted as visible light. This idea aims to create an incandescent light bulb that keeps the warm glow but matches LED's efficiency. While promising from a research perspective, such designs remain largely at the laboratory stage. However, it has to face costs and manufacturing barriers.
However, considering various factors, the likelihood of incandescent bulbs making a large-scale return to the mainstream market is low. If high-efficiency incandescent bulb technology is commercialized in the future, it may bring new market opportunities. That said, there is still considerable uncertainty at present. In the meantime, energy-saving policies remain the core factor driving the development of the industry. The global carbon neutrality goal requires continuous reduction of energy consumption in the construction and industrial sectors, which further compresses the space for the return of incandescent lamps.
