Thanks for the help! The extra outlet will also only be lightly used. Definitely not adding any kind of constant load on that circuit. The second closet is quite large and I wanted to plug in a single LED strip and run it around the room with a switch so I can see when I have to dive in to that room to find something. Considered just branching off to run light fixtures and stuff, but the ceiling is really low in places (under the stairs) and I think just running a little LED strip around would be easier and more effective.
