Installing a wall sconce requires turning off the breaker, connecting matching wires, and securing the fixture to the outlet box.
For the full breakdown, see our best Plug-In Bedroom Wall Sconces guide.
Wall sconces bring layered lighting and character to hallways, bedrooms, and reading nooks. The job splits into two clear paths: hardwired sconces that connect to your home’s electrical system, and plug-in sconces that simply mount to the wall and plug into an outlet. Both are manageable for a capable DIYer, but the safety rules and the steps differ. Here is the practical order of work for each.
What You Need Before Starting Any Sconce Install
Shutting off power at the main circuit breaker panel or fuse box is the first move, and Kichler’s installation guide insists it stays off until the work is complete. Turning off only the wall switch is not enough.
Gather the essentials before you begin:
- Voltage tester to confirm the circuit is dead
- Screwdrivers (flathead and Phillips)
- Wire strippers and a wire nut set
- Drill with bits and a level
- Drywall anchors if you are not hitting a stud
Hardwired Sconce Installation: The Full Wiring Sequence
Hardwired sconces replace an existing fixture or connect to a prepared electrical box in the wall. The mounting plate must sit flush against the outlet box, with the fixture’s slots or knockouts lining up with the box’s screw holes.
Follow this order once the power is verified off:
- Remove the old fixture and disconnect its wires. Keep the outlet box exposed.
- Position the mounting plate flat against the electrical box, aligning its slots with the box’s holes, then secure it with the provided screws.
- Connect the ground wire first. Attach the fixture’s bare copper wire to the green ground screw on the mounting plate, and connect it to the box’s ground wire. Never connect ground to black or white supply wires.
- Match black to black and white to white. Twist each pair together and cap them with a wire nut.
- Push the sconce flush to the wall, aligning the canopy’s holes with the mounting plate, then tighten the canopy screws or finials gently.
Overtightening is a common misstep. Schoolhouse warns that too much force can damage the canopy or strip the threads. Snug is sufficient.
For retrofit work where no box exists, Stone’s Home Centers advises cutting an opening with the manufacturer’s template, running cable with fish tape, and securing a new electrical box into the stud. If that feels beyond your comfort zone, stopping and calling a licensed electrician is the right call.
Plug-In Sconce Installation: Simpler Mounting, No Wiring
Plug-in sconces skip the electrical connections entirely. The cord runs from the fixture down to a nearby outlet, so the work is all about clean mounting.
Schoolhouse’s plug-in guide gives the practical sequence:
- Mark the location and confirm a stud is not required.
- Pre-drill and insert drywall anchors. Many kits, Schoolhouse notes, do not include anchors or screws, so buy the right size for your wall type.
- Install the mounting bracket onto the anchors.
- Tighten the canopy screws to secure the sconce base.
- Plug the cord in and route it neatly along the wall.
For heavier fixtures, skip the anchors and drive the bracket screws directly into a wall stud. Drywall anchors work for light fixtures but will not hold substantial weight.

Aligning Multiple Sconces and Avoiding Common Mistakes
One crooked sconce ruins the whole look. For a pair or a row, Stone’s Home Centers recommends marking the height with a level and snapping a chalk line across the wall so every fixture sits in perfect alignment.
The mistakes that bite most often are avoidable:
- Working off the wall switch only instead of the breaker. A switch can be on while the box is still live.
- Connecting ground to a black or white wire. Ground goes to the green screw or the box’s bare wire, period.
- Misaligning the canopy holes before tightening, leaving the plate crooked against the wall.
- Overtightening screws, which strips threads and cracks the canopy.
If your home’s wiring lacks a ground and you are not sure the system has a grounding means, Lowe’s installation guide carries a blunt warning: do not proceed. That uncertainty is a job for an electrician, not a DIY weekend.
After the final screw is snug and the power is back on, test the switch. When the light glows evenly and the canopy sits flush, the install is done. If you chose a plug-in model, the same test is simply flipping the cord switch — no breaker involved.
FAQs
Do I need an electrician to install a wall sconce?
Not always. If you are replacing an existing fixture at a prepared outlet box, a confident DIYer can handle the wiring. If no box exists, you need to run new cable through the wall, or the house lacks proper grounding, that work is best left to a licensed electrician.
How high should a wall sconce be mounted?
Standard height puts the center of the sconce about 60 to 66 inches above the floor. For bedside reading lights, mount them lower, roughly 48 inches up, so the light sits above your head when you sit up in bed.
Can I install a plug-in sconce without drilling into a stud?
Yes. Plug-in sconces are light enough for drywall anchors. Pre-drill the holes, tap in anchors rated for the fixture’s weight, and the bracket will hold firmly. For heavier fixtures, drive the bracket screws straight into a stud instead.
