What lightbulb for vertical light fixture

Oops. It looks like I can't post photos.. (?)

does it look like a fixture you would find in an actor's dressing room? Google "Bathroom vanity light" to see what I mean.

Take a photo of it and take the photo to Just Bulbs, 222 E 58th St -- knowledgeable and helpful crew for anything from a $1 led to expensive custom units.

Just need to determine if you need chandelier base bulbs or regular base. Both types are sold in most hardware stores.
Chandelier base come in round of different wattages (which are usually what would go around mirrors) as well as candelabra style for sconce fixtures

Take the bulb and go to a good hardware store

I vote for Just Bulbs. Take the bulb there. You may have to wind up replacing them all to get a color match.
