Why does my semi flush ceiling light sit crooked on a sloped ceiling?

Why does my semi flush ceiling light sit crooked on a sloped ceiling? Many flush mounts need a slope adapter before they sit flat on a sloped ceiling. Check the canopy on the product page. If the junction box is loose, cracked, or not rated for the fixture, stop and hire an electrician.

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.
