Video Conference Lighting
Providing proper lighting for a video conference
space is important to ensuring optimal image
quality. Here are the problems and some
suggested solutions.
1. Provide lighting for the camera in the proper
quantity, quality and angle. The light should come
from an angle between 45° and 60° vertical.
Optimum
angles of light
onto the face
45°
60°
Camera
Horizontally, light should
also be cast on the face
from an angle in addition
to front. This will assure
(2 m)
that minimum shadows 6onftcenter
are created in the eye
sockets and under the
nose and chin.
The amount of light falling
on the face of the subject
measured vertically should
be 50-75 fc. The quality of
light can be assured by using
fluorescent lamps of 3500 °K (Color Temperature)
Position light meter
with a CRI (Color Rendering
vertically, not horizontally.
Index) of 82+. The use of high
color temperature lamps (5700 °K and higher) is not necessary for video
cameras as the strong blue component makes
most skin tones look bad (blue).
2. Provide minimal lighting for the screen or monitor
for good screen contrast and image sharpness.
The wall where the screen or monitor is located
should have reduced illumination. No reflected
glare should appear on the screen or monitor to
inhibit viewing. The contrast of the screen to the
surrounding areas (or monitors) should be to 10:1
with the display being the brightest.

3. Provide lighting for the back wall and to a lesser
extent, the side walls to balance the brightness
with the rest of the room. Doing this will prevent the
camera from irising on the back or side walls that are
too dark or too bright. This can allow too much or too
little light into the camera resulting in the appearance
of over or under lighting the subject. Generally,
Iris of camera

overlit.
the wall finishes and furniture should be neutral.
The reflectance value of these colors and surfaces
should be around 30-40%. Light level ratios from the
participant to the back wall should be within 3 to 1
while the side walls can be 5 to 1.
Solutions: To accomplish the above requires light
fixtures that provide a wide horizontal component.
The VTC Series fixture
from Lutron that is
designed for this use is
a recessed, indirect 2 x 2 foot with two 50
W twin tube lamps.
This fixture produces an
asymmetric distribution
that provides a large
horizontal throw in
three directions. Very
little light is directed
behind the VTC Series
fixtures so they do not

screen or glare into the
camera. The tri-directional
performance of this product often eliminates the need
for additional lighting on back and side walls, so the
third consideration is handled also. A lighting layout
example has been provided on the next page.
Dual Function and Participant Comfort: The VTC
Series is provided with a dimming ballast so you may
adjust the light levels for optimum picture quality and
have low light level illumination for other conferencing
functions. Combining the low heat of fluorescent
lamps with an indirect optical system, the participants
in the room will have optimum comfort visually and
environmentally.

A Photometrics Example
Vertical light levels on participants should be
a minimum of 50 to 70 fc for successful video
conferencing. Light readings are shown in foot
candles and were calculated with Lighting Analysts’
