Electrical – Old Work Box for Vanity Light


So I went to go change my bathroom vanity light today and discovered that it simply had the wiring coming through a hole in the wall and the previous vanity was literally just screwed into the wall with 2 screws.

Went to the local home improvement store and the employees guided me to some old work boxes that look like this:

So I get it installed, but it had me wondering…is this safe? I mean the vanity light isn't THAT heavy (I weighed it at around 3 lbs). I do not have a stud nearby (that I can see anyways) (nor would it matter because I would need to have access behind it anyways), and I really don't want to be tearing out an entire wall ideally)

Is this ok? I looked at various guides on changing or adding vanity lights and most seem to use these boxes (Which "seem" to be rated for 6 lb's, and only mention NOT to use them for ceilings).

Yes, an old work box is completely safe for what you're using it for. Just make sure the dogs are snug against the drywall.
