Lighting Considerations For the TX9000 and TX9200
The Cisco TelePresence TX9000 and TX9200 system require the following lighting levels.
Overhead Lighting Examples for Cisco TelePresence Rooms
Figure 2-3 and Figure 2-4 illustrate lighting examples for Cisco TelePresence rooms. The option you
choose depends upon your choice of lighting fixtures.
Caution
The following examples are for reference only. Please consult your lighting manufacturer specifications
for the adequate number and proper layout of fixtures to achieve the lighting levels mentioned in
Table 2-7 . For example, lights that are brighter than the averages tested for this guide may require fewer
placements. Likewise, light sources that are dimmer than the averages may require a greater density of
fixture placements.
Table 2-7 TX 9000 and TX9200 Room Lighting Levels
Illumination Target Tolerance Note
Overall illumination
lux (= lm/m2)
200-400 lux
Systems that use 60 FPS
conferences require
measurements closer to
400 lux.
Lighting should be evenly
dispersed throughout the room.
Lighting should not fluctuate
more than 100 lux throughout the
room.
Measured vertically w/ light sensor
pointed at wall or intended camera
location (not pointed at ceiling),
3’ 11” (1.20 m) above the finished
floor (AFF).
Wall wash 200-400 lux Lighting should be evenly
dispersed throughout the room.
Lighting should not fluctuate
more than 100 lux throughout the
room.
Measured vertically w/ light sensor
pointed at wall or intended camera
location (not pointed at ceiling),
3’ 11” (1.20 m) above the finished
floor (AFF).
Shoulder light/Direct
down light. 400-800 lux or lower
when possible Generally, shoulder lighting
should not be more than twice the
facial light. Measured horizontally at table
height w/ light sensor pointed at
ceiling, 3’ 3” (0.99 meter) AFF.
Lighting Dispersion
Color Temperature
Etc.
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.
