I rent an apartment, so I cannot do any huge electrical renovations or projects, nor do I want to. But I've had this very old vanity light that looks like it's from the 1950's. I want to update my bathroom and I'm wondering if I can replace this vanity lights shade (the front glass part) only. Or if I have to buy a whole new hardwired light fixture. I can't find any information on this light at all. I'm in denial about having no choice but to live with this ugly thing as long as I live here.
