The approach of using daylighting strategies and LED technology is highly effective for enhancing energy efficiency in lighting. Daylighting strategies utilize natural light to illuminate spaces, which can significantly reduce dependence on artificial lighting during daytime. This not only conserves energy but also enhances occupant comfort and can lead to reductions in electricity costs.

Incorporating LED technology is equally important, as LEDs consume up to 75% less energy than traditional incandescent bulbs while providing the same level of brightness. LEDs also have a longer lifespan, which reduces the frequency and costs associated with replacements and maintenance. These combined practices can lead to a substantial decrease in energy consumption associated with lighting.

In contrast, implementing more incandescent bulbs would actually increase energy usage, as these bulbs are less efficient. Installing larger fixtures does not inherently improve energy efficiency and can even lead to additional energy consumption if not paired with energy-efficient bulbs or strategies. Focusing solely on aesthetics neglects the critical consideration of energy efficiency, ultimately leading to higher operational costs and a negative impact on sustainability efforts. Thus, the combination of daylighting and LED technology presents a holistic and effective approach to improving energy efficiency in lighting systems.
