Turn on the recessed lights and any other lights in the room, such as a chandelier, pendant light or lamps. Check the lighting at night, to see if the illumination is adequate for task lighting, if needed.
Extend a tape measure from the floor to the center of a light. Check that the tape measure is straight. Mark the floor with masking tape or painter's tape directly below the light. Measure from the light to the nearest wall in a straight line and then mark the light's location on the grid, using a 1-inch-to-1-foot scale. Alternatively, if you have a copy of the house plans or room plan, check if the light positions are marked. This will help you center a table with the recessed lights.
Position the table under the recessed lights so it receives even illumination, if possible. For example, center a table under two rows of recessed lights on one side of the kitchen, using the grid plan as a guide.
Adjust the table's position to allow enough space for walkways and to pull out the chairs, if necessary. As a general rule, allow 36 inches for chairs to pull out from the table, and increase the amount of space if the household includes people who need more clearance, such as a person who uses a wheelchair or a walker. For example, center the table under one row of recessed lights, instead of between two rows of lights, to allow enough room between the table and the wall, if needed.
