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.
Choose a rectangular chandelier for a rectangular table that is in keeping with the proportions of the table. For example, for a table that is 54 inches wide and 72 inches long, the diameter should be 27 inches. Subtract 27 inches from the length of the table for the result of a length of 45 inches. The rectangular chandelier best proportioned to this table would be 27 inches wide and 45 inches long.
