The light bulbs that have largely been stopped from being made for general lighting are incandescent light bulbs.
The Phase-Out of Incandescent Bulbs
A ban covering most incandescent light bulbs in the United States took effect in 2023. This measure was implemented primarily due to the energy inefficiency of these traditional bulbs, as they convert a significant portion of energy into heat rather than light. While the initial purchasing expense of alternative light bulbs like LEDs or CFLs can be higher, their long-term energy savings and extended lifespan typically outweigh this upfront cost.
Why Incandescent Bulbs Were Phased Out
The decision to phase out incandescent bulbs stems from a global push towards more energy-efficient lighting solutions.
- Energy Inefficiency: Incandescent bulbs operate by heating a filament until it glows, with most of the energy released as heat (around 90%), making them highly inefficient in terms of light production.
- Environmental Impact: Reduced energy consumption from more efficient bulbs lowers greenhouse gas emissions from power plants.
- Economic Savings: While the initial cost of alternatives might be higher, consumers save money over time due to lower electricity bills and less frequent bulb replacements.
Understanding the Change
The shift away from incandescent bulbs impacts both consumers and manufacturers.
Key Changes in Lighting Options
| Light Bulb Type | Status (Post-2023 US Ban for General Lighting) | Key Characteristics |
|---|---|---|
| Incandescent | Largely Phased Out / Banned | Inefficient (high heat output), short lifespan, warm glow, low initial cost. Some specialty incandescents may still be available. |
| LED (Light Emitting Diode) | Primary Replacement / Widely Available | Highly energy-efficient, long lifespan (up to 25,000+ hours), versatile in color and brightness, higher initial cost. |
| CFL (Compact Fluorescent Lamp) | Available but Less Common than LED | Energy-efficient (less than LED), spiral shape, contains small amount of mercury, takes time to reach full brightness. |

What This Means for Consumers
While traditional incandescent bulbs for general lighting are no longer widely available, consumers have excellent alternatives that offer superior performance and energy savings.
- Embrace LEDs: LEDs are the most recommended replacement. They come in various shapes, sizes, and color temperatures, mimicking the warm glow of incandescents if desired, but with significantly lower energy consumption and much longer lifespans.
- Consider CFLs: Though less common than LEDs for new installations, CFLs still offer energy savings over incandescents.
This transition reflects a broader commitment to sustainable energy practices and offers long-term benefits for both the environment and household budgets.
