What size three light flush mount ceiling light should I buy?

What size three light flush mount ceiling light should I buy? A common decorator rule adds the room length and width in feet and uses that number as the fixture diameter in inches. A 10 by 12 foot room points to about a 22 inch fixture. Over a table, many designers choose a fixture about one half to two thirds of the table width. These are retail rules of thumb, not a lab measurement.

How to decide

  • Match the room: flush mount on an 8 foot ceiling, pendant or chandelier only where people will not hit it.
  • Read lumens, kelvin, and dimming on the product page. Do not invent a rating the page does not show.
  • Confirm any minimum order before you add the item to a wholesale cart.
  • If the ceiling box is loose, cracked, or not rated for the fixture, hire an electrician.
