Using technology similar to the Jet PCM, the Jet module provides the ultimate in power tuning. Point-by-point air/fuel, ignition advance, transmission, and various other tuning points provide performance gains and, in some cases, improved fuel economy.
In this case, a chandelier with a diameter of 20 inches would work well in an 8-foot by 12-foot room. For a dining room, the chandelier should have a diameter around 12 inches less than the table is wide. It's always better to have a chandelier that is slightly too big than too small. Measure for the length.
This is the diameter of the chandelier that will best suit the room. Allow 2 to 3 inches of chandelier length per foot of wall height. For example a dining room with 10-foot ceilings, 16 feet wide and 18 feet long, can accommodate a chandelier 34 inches in diameter and 20 to 30 inches in length.
