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.
Choosing the right chandelier for rooms other than the dining room is tricky, as you don't have a table to help with measurements. The chandelier should be centered in the room (unless very tall furniture are present within the room, for example a four poster bed) and be at least 7 feet from the floor.
