Hi! I need to pick out light bars for my new home and although I would have preferred light fixtures on each side, I am stuck with center top over a mirror. I haven't selected the mirror sizes yet. What would be the optimum sizes?

If you want to use a medicine cabinet I would probably stay with the 24 inch and use side lights. You'll need to keep in mind that a bar light above the medicine cabinet will need to extend enough to clear the depth of the cabinet, so finding such a light may be difficult. There are cabinets that have built-in lights so you may want to look at those. Check these out. If you choose a cabinet with built-in lights, I'd go with a wider than 24" cabinet. Other option: keep the light fixture you have and put in a framed, or unframed mirror that is a little wider than the lights. Here are some visuals.

I think a 3-light will probably work. A 2-light in a powder room, maybe, but you'll want something like 3x65W equivalents of light to get ready in the morning. As long as it's not wider than your vanity, a little larger or smaller than the mirror is not likely to be noticeable.

The mirror is 24x26. The 24" vanity bars are just too overwhelming. Would love opinions on whether 18" (yellow), 15" (green) or 12" (red) would balance better. Thanks!
