Light quality is a key factor in downlight design. A high color rendering index (CRI) and appropriate color temperature can improve the comfort of the indoor environment. For example:

Color rendering index (CRI): A high CRI value (such as Ra＞90) can present the color of objects more realistically and improve the visual effect of the space.

Color temperature selection: Warm white light (2700K-3000K) is suitable for creating a comfortable atmosphere, while cool white light (3500K-5000K) is suitable for areas that require efficient work.
