Which of the following methods can help minimize glare in lighting design?

Utilizing diffusers and proper fixture placement is an effective method for minimizing glare in lighting design. Diffusers work by softening and scattering the light emitted from fixtures, which reduces the intensity of direct light and helps to create a more uniform illumination. This not only diminishes the harshness of the light perceived by the viewer but also helps to manage the overall brightness levels in a space, ensuring that the lighting is comfortable and visually appealing.

Proper fixture placement is equally important; strategically positioning fixtures can prevent direct line-of-sight views of bright light sources, which are a common cause of glare. By placing fixtures in optimal locations, lighting designers can enhance visibility while reducing discomfort from bright light spots.

In contrast, using brighter bulbs can actually increase glare, as higher intensity light can be more difficult for the eyes to adjust to. Increasing fixture elevation may help certain situations but doesn't guarantee glare reduction, as it can sometimes create line-of-sight issues instead. Reducing the number of light sources could lead to insufficient lighting levels, which doesn't effectively address glare but merely lowers overall brightness. Therefore, utilizing diffusers and proper fixture placement stands out as the most reliable approach to minimize glare effectively.
