Why CFL or LED bulbs should be used instead of conventional bulbs?

Options

A. They emit more light energy.
B. They require less power to run.
C. They can run without electricity
D. They clean the pollutants in the air

Answer

### Step-by-Step Solution:

1. **Understanding the Types of Bulbs**:
- Conventional bulbs (like incandescent bulbs) are traditional light sources that use a filament to produce light.
- CFL (Compact Fluorescent Lamp) and LED (Light Emitting Diode) bulbs are modern alternatives that use different technologies to produce light.

2. **Energy Efficiency**:
- CFL and LED bulbs consume significantly less energy compared to conventional bulbs.
- For example, a 10W LED bulb can produce the same amount of light as a 60W incandescent bulb.

3. **Longevity**:
- CFL and LED bulbs have a longer lifespan.
- An LED bulb can last up to 25,000 hours, while a conventional bulb may only last about 1,000 hours.

4. **Cost-Effectiveness**:
- Although CFL and LED bulbs may have a higher initial purchase price, their longer lifespan and lower energy consumption result in cost savings over time.

5. **Environmental Impact**:
- Using CFL and LED bulbs reduces electricity demand, which can lead to lower greenhouse gas emissions from power plants.
- They also contain fewer hazardous materials compared to some conventional bulbs.

6. **Light Quality**:
- CFL and LED bulbs can provide better light quality, with options for different color temperatures and brightness levels.

### Conclusion:
CFL and LED bulbs should be used instead of conventional bulbs primarily due to their energy efficiency, longer lifespan, cost-effectiveness, reduced environmental impact, and improved light quality.
