A company acquired immersive Cisco TelePresence devices and they are setting them up in a dedicated Cisco TelePresence room. Which two options are recommendations for the lighting of the room?…

Direct lighting is not recommended because it creates harsh shadows and glare on participants' faces; indirect or diffused lighting is preferred.

A color temperature of 5000K to 5100K is too cool and produces a bluish tone that distorts skin color rendering on camera.

A CRI of 82 and above ensures that the lighting renders skin tones and colors faithfully on camera, which is critical for the realistic appearance required in immersive TelePresence environments.

A color temperature of 4000K to 4100K produces a neutral-to-warm white light that is specifically recommended by Cisco for TelePresence rooms because it accurately reproduces natural skin tones without the blue cast of higher color temperatures.

Cisco recommends facial lighting levels between 300 and 500 lux; the 400-600 lux range listed here exceeds the upper boundary of the recommended specification.
