Target
200-400 lux
Systems that use 60 FPS
conferences require
measurements closer to
400 lux.
200-400 lux
400-800 lux or lower
when possible
Dimmable lighting systems optional but highly recommended for Cisco TelePresence rooms.
If you use a dimmable system, you must commission the system before you take final calibration
and lighting measurements. A dimmable system allows greater lighting control. The target is
four-zone controlled lighting with scene presets.
Asymmetric lights with light dispersion more than 45 degrees are recommended; however, you can
use any lighting that meets the overall lighting requirements.
For all other general Cisco TelePresence room lighting recommendations, refer to the
