Can a ceiling light be installed without an existing fixture?

Can a ceiling light be installed without an existing fixture? A like-for-like swap on a sound box is a basic job: breaker off, ground to ground, white to white, hot to the switched hot. A new box, damaged cable, aluminum wire, or a fan on a light-only box needs a licensed electrician.

How to decide

  1. Photograph the old splices first.
  2. Stop if you see scorch marks or more hots than the new fixture has leads.
