I am installing a new vanity light. I took down the old one from 1997 and found that there is no box behind the light, only the cable coming through the drywall, (black, white and green/ground.) Is it okay to just hook up the new fixture to this set up? Why would there be a need for a box?

  • what does the new light look like and how does it attach to the wall? May 24, 2019 at 12:42
  • It's a brand new Portfolio 4 light bar light from Lowes. It's not used, so modern technology...Metal housing.lowes.com/pd/…

The question depends entirely on whether the fixture acts as its own junction box, with full containment and a strain relief clamp. If it includes a UL listed enclosure, all good. The instructions should make this fairly clear.

If not, grab an old work (remodeler) box and pop it in. Be sure you'll clear your studs before you start cutting drywall.

  • Thank you! The new light has a UL listed enclosure, saving me time, work and worry.
