Which light is recommended by cisco?

Direct lighting aimed straight at participants causes harsh glare and flat shadows, which Cisco identifies as detrimental to video image quality.

Indirect lighting diffuses illumination broadly across the room, reducing contrast and facial definition rather than providing the targeted illumination Cisco recommends.

Point lighting provides a focused, directional light source that Cisco identifies as optimal for video conferencing environments because it delivers consistent, controllable illumination on participants' faces. This type of lighting minimizes unwanted shadows and glare that can degrade video image quality on Cisco endpoints. Cisco's room design guidance specifies point lighting as the preferred approach for achieving accurate color rendering and clear facial detail.

Reflector-based lighting is not specified in Cisco's official room design recommendations as the preferred lighting type for video conferencing rooms.
