For led downlight, there are many kinds of beam angle, like 12degree, 24degree, 36degree, 60degree. Narrow beam angle output concetrated light which is better for accent lighting. Wide beam angle output widely light, more softer light. See the light effect of difference beam angle:
When the light have to directed to a specific object, not a big area, recommend to choose narrow beam angle, like 12degree.
When the light have to light up a large room, like living room, recommend to choose 60degree.
If you are not sure which beam angle is better, you can contact us to do lighting simulation. Which can help you to make the right desicion.
