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.
Avoid purchasing chandeliers that are larger than the width of your table, as people may bump into it when getting up. A handy rule of thumb is that a chandelier should be 12 inches narrower than a table and have at least 48 inches of space from each of the room walls or edges. Hang a chandelier approximately 30 to 34 inches over a table with an 8 foot ceiling height. If your ceiling is higher than 8 feet, mount the chandelier an additional 3 inches higher for each foot of ceiling.
