A technician is tasked with performing a room readiness assessment in preparation for an immersive video endpoint. What are three Cisco best practices regarding lighting recommendations for the room?

A color temperature of 4000-4100K is recommended by Cisco because it produces a neutral white light that accurately renders skin tones without introducing warm or cool color casts in the captured video image.

Cisco recommends measuring key lighting levels with the endpoint powered off to prevent display light from skewing ambient light readings, making the 'powered on' condition in this choice incorrect.

Shoulder lighting should not exceed two times the facial lighting value to maintain a natural contrast ratio and avoid washing out facial features or creating harsh shadows on participants.

Cisco recommends indirect or diffused lighting fixtures rather than direct lighting, to avoid harsh shadows and glare artifacts on participants and surfaces.

Lighting uniformity within the camera field of view ensures that no area of the room appears significantly brighter or darker than another, preventing distracting hotspots or shadows that degrade perceived video quality.

Dimming light control systems are not prohibited by Cisco best practices; they are acceptable provided the resulting light levels and color temperature still meet the specified requirements.
