Installing a pendant light on an existing box is a beginner electrical job — plan on 30 to 45 minutes, $40 to $250 for the fixture, and no permit for a like-for-like install. You set the hanging length, connect three wires, and mount the canopy. Over an island or table, hang the bottom of the pendant 30 to 36 inches above the surface. Kill the breaker and verify the wires are dead first, and confirm the box is secure and within its 50-pound rating. New boxes and panel work are for a licensed electrician.

Tools and materials
- Non-contact voltage tester, screwdrivers, wire strippers, and a stepladder.
- Wire nuts or lever connectors, and the pendant's mounting strap (included).
- A tape measure to set the 30-to-36-inch hanging height.
- The pendant. For a bare-bulb style, a good-looking bulb matters — see our best smart bulbs picks for dimmable, warm options.

Step 1: Cut the power and verify dead
Switch off the breaker feeding the box, leave the wall switch on, and after removing any existing fixture, confirm the wires are dead with the voltage tester. No beep on any wire before you touch bare copper.
Step 2: Set the hanging length
Decide the height now, on the ground, not overhead. Measure from the ceiling to where the bottom of the pendant should sit — 30 to 36 inches above an island or tabletop. Adjust the cord, rod, or chain to that length: coil and secure excess cord, remove chain links, or choose the right rod section. Getting this right before wiring saves you wrestling the fixture twice.

Step 3: Fit the strap and check the box
Screw the mounting strap to the ceiling box and confirm the box is solid and within its 50-pound rating. Feed the pendant's cord or rod through the canopy and thread the mounting hardware so the canopy will sit flush once wired.
Step 4: Connect the wires
Connect black (fixture) to black (ceiling), white to white, and the ground lead to the ceiling ground and the strap's green screw. Strip nicked ends to clean copper first. Twist each pair clockwise, cap with a wire nut or seat in a lever connector, and tug to confirm. Fold the wires neatly into the box.

Step 5: Mount, power, and test
Raise the canopy to the ceiling and secure it with the collar or screws so it sits flush and level. Install the bulb within the wattage limit. Restore the breaker, switch on, and confirm steady, flicker-free light at the height you planned. Step back and check the pendant hangs plumb and level; a crooked canopy usually means the strap screws are uneven.
Common mistakes
- Setting the height overhead by guesswork. Measure and set the length first, 30 to 36 inches above the surface.
- Cutting the cord. Coil the excess unless the instructions say otherwise.
- Loose splices. The usual cause of flicker. Twist firmly, tug to check.
- Ignoring the box rating. Heavy clusters need a fan-rated box.
- Skipping the ground. Land it every time.
When to call an electrician
Bring in a licensed electrician if there is no box where you want the pendant and one must be added, if the wiring is aluminum or cloth-insulated, or if the job reaches the panel — permit-and-pro work, jurisdiction-specific, never DIY at the service panel. A plug-in swag pendant is the no-wiring alternative when there is no box at all. Hanging a hardwired pendant on a sound box is a homeowner job.
