Although floor lamps and table lamps obviously differ in their typical size and placement both have the ability to add gentle task lighting for reading while also infusing a general glow wherever they stand targeting anywhere from the center of a room (say on a sofa table) to a dim corner.
Adding lights as decorative elements helps set a mood in a space. Provided that general lighting is already installed using lights instead of wall art can be a decorative way to provide ambient lighting.
Don’t think that adding lights to your toe-kicks is a frivolous aesthetics-only decision. Strip lighting at the underside of base cabinets is a great way to create a night light that looks fabulous.
