TELECONFERENCE LIGHTING RECOMMENDATIONS

1. I.E.S. recommends 50 maintained footcandles for telecon-

ferencing.

2. 3000K lamps with C.R.I. of 82 suggested for better skin tone.

3. Teleconferencing luminaires are to be mounted in the

ceiling with the lamps perpendicular to the wall that the

viewing screen is on.

4. The end of the first fixture must be a minimum of 6 feet

from the viewing screen (see diagram).

5. Side and back walls should be illuminated to reduce

contrast vs. other vertical surfaces. Use wall lighting luminaires where nec-

essary. 5:1 maximum luminance ratio

suggested.

NOTE: For wall lighting, request Folio K20-05.
