Our friend just IM'ed us about happily ordering their own ceiling light shade to replace the ones that came with her rental unit. She wanted us to also recommend another good idea for bringing in overhead lighting in a rental situation: swag chandeliers.
She's purchasing one of these affordable swag chandeliers to bring in illumination in a formerly dark corner, noting their affordability and the ease of installation, only requiring a ceiling hook to hang the lamp without worry about electrical wiring. Partner it up with a wireless remote, and you've got a lighting solution you can easily change back if you have to move with just a minor ceiling patch. Lamps Plus has a wide selection of graphic prints in a modern shade finish for $99 including chain and wires.
