Review Questions

• How does LED lighting compare to traditional incandescent bulbs in terms of energy efficiency and lifespan?
  • LED lighting is significantly more energy-efficient than traditional incandescent bulbs, using up to 80% less energy to produce the same amount of light. Additionally, LEDs have a much longer lifespan, often lasting 25,000 hours or more compared to the 1,000 hours typical for incandescent bulbs. This combination of efficiency and longevity makes LEDs a preferred choice for both residential and commercial applications.
• Discuss the importance of lumens as a measure in evaluating different lighting technologies and how it impacts consumer choices.
  • Lumens are critical for understanding the brightness produced by various lighting technologies. Higher lumen output indicates brighter light, which is essential for consumers when selecting bulbs for specific spaces. By comparing lumens across different types of lighting, consumers can make informed choices based on their illumination needs, ensuring they achieve the desired ambiance and functionality in their environments.
• Evaluate the impact of smart lighting technology on energy consumption and user convenience in modern homes.
  • Smart lighting technology has transformed how we manage our home lighting by providing significant benefits in energy consumption and user convenience. With features like remote control via smartphones, scheduling, and automation based on occupancy or ambient light levels, users can optimize their energy use while enhancing comfort. This not only leads to lower utility bills but also contributes to sustainability efforts by reducing overall energy demand in homes.
