Which of the following would NOT be an appropriate recommendation for a chandelier?

The recommendation stating that the diameter should be 1 inch less than the width of the dining table would not be appropriate for a chandelier. Ideally, a chandelier should have a diameter that is proportional to the table it is above, typically recommended to be between half to two-thirds the width of the table. This ensures that the chandelier is visually balanced and provides adequate lighting without overpowering the space or crowding the table.

In contrast, the other options reflect better practices for chandelier selection and installation. The suggestion regarding the diameter being equal to the sum of room length and width in feet aligns with a common guideline for room proportion and ensures the chandelier is appropriately scaled to its surroundings. Installing the chandelier at 30 inches above the table top is a widely accepted height that allows for optimal lighting while maintaining an unobstructed view across the table. Furthermore, incorporating dimming controls facilitates adjustable lighting levels, enhancing the atmosphere and usability of the space.
