Finding the Right Sconces-wall-lights for You
From the kitchen to the bedroom and everywhere in between, there is one major part of home decor that you definitely want to master: lighting. Carefully selected vintage sconces and wall lights can do wonders in establishing mood and highlighting your distinctive personality.
We’re a long way from the candelabra-inspired chandeliers of the medieval era. Lighting is no longer merely practical, and lighting designers have been creating and reinventing lighting solutions for eons. Because of the advancements crafted by these venturesome makers, we now have the opportunity to bring unique, customizable lighting solutions into our homes.
It’s never been easier to create dramatic bedrooms, cozy kitchen areas and cheerful bars than it is today. Think of an elegant wall sconce as functional and as a work of art, adding both light and style to your hallways, whimsical kids’ rooms and elsewhere.
When choosing a lighting solution, first determine what your needs are: Will you opt for a moody or a bright feel? The room that will serve as your home office will need adequate lighting — think “the brighter, the better” for this particular setting.
For the bedroom, bedside wall lamps with warm-temperature bulbs instead of bedside table lamps could be the way to go to induce a sense of calm or intimacy. Try to match the style of the wall light or sconce that you’re installing to the overall design scheme of your room. It’s never “just a light.” You should approach the lighting of a room with a mindset that is one part practical and one part aesthetics-driven.
Let 1stDibs help you set the mood with the right antique and vintage wall lights and sconces for your home. Our collection includes every kind of fixture, from sculptural works by Austrian craftsman J.T. Kalmar to chic industrial-style wall sconces, from adjustable painted aluminum wall lamps designed by Artemide to a wide variety of minimalist mid-century modern masterpieces.
Questions About Iconic Wall Sconces
- What is a plug in wall sconce?1 Answer1stDibs ExpertOctober 12, 2021A plug-in wall sconce is perfect for upgrading the lighting of the room without investing in hardwired fixtures. It can be easily mounted on a wall without having to call an electrician for rewiring purposes. This sconce will amazingly blend with traditional as well as contemporary décor. Shop a range of antique and vintage plug-in wall sconces on 1stDibs.
- 1stDibs ExpertMarch 22, 2024The difference between a sconce and a wall lamp is that a sconce is a type of wall lamp or wall lighting fixture. The term sconce is usually used to refer to a decorative lighting fixture whereas a wall lamp might refer to recessed lighting, spotlights or track lighting.
Usually installed in pairs or groups, sconces are decorative fixtures used to light hallways, or placed on either side of a door or bed. In addition to ambient illumination, they can provide upward or downward directional lighting, or both.
