The color rendering index is an indicator to measure the downlight's ability to restore the color of an object. The higher the color rendering index, the more realistic the object's color. The CRI of LED downlight is at least larger than 85Ra.
The beam angle refers to the angle formed by the light emitted by the downlight in the space. Different beam angles are suitable for various lighting needs.
Downlights with narrow beam angles (15° - 24°) are suitable for accent lighting, such as illuminating decorations, paintings, etc.
Downlights with medium beam angles (24°- 45°) are suitable for general lighting, such as illuminating the entire room.
Downlights with wide beam angles (above 45°) are suitable for wall-washing lighting, such as illuminating walls or ceilings.
The immediate effect of glare is that our eyes feel uncomfortable and are more susceptible to eye strain. So, the anti-glare is also essential.
