TELECONFERENCE LIGHTING RECOMMENDATIONS
1. I.E.S. recommends 50 maintained footcandles for teleconferencing.
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 perpen-
dicular 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 sur-
faces. Use wall lighting luminaires where necessary. 5:1 maximum luminance ratio
suggested.
NOTE: For wall lighting, request Folio K20-05.
