How to Install a Linear L-Bar Wall Light

Quick answer

To install a linear L-bar wall light, first turn off power, then mount the backplate, connect the wiring, attach the L-bar arm, and secure the shade. Always double-check polarity and use a voltage tester before touching wires.

Step-by-step installation guide

1. 1. Turn off power and test: Switch off the circuit breaker for the light circuit. Use a voltage tester on the existing wires to confirm no current is present. Common mistake: assuming the wall switch kills power — the breaker may still be live. Always test wires, not just the switch.
2. 2. Remove old fixture and prepare wires: Unscrew the old light and disconnect the wires. Strip about 1/2 inch of insulation from the ends of the supply wires (black/hot, white/neutral, green or bare/ground). If wires are frayed or brittle, trim back to fresh copper. If the supply wires are too short, splice on a short extension using wire nuts.
3. 3. Mount the backplate: Hold the backplate against the wall, level it, and mark screw positions. Drill pilot holes and insert wall anchors if needed. Secure the backplate with the provided screws. Common mistake: overtightening can crack the backplate or strip the anchor. Hand-tighten screws, then give a quarter turn with a tool.
4. 4. Connect the wiring: Match the fixture wires to the supply wires: black to black (hot), white to white (neutral), and ground to ground. Twist each pair together with a wire nut and tug gently to confirm a solid connection. Common mistake: reversing polarity (hot/neutral) will work but is unsafe — double-check. Wrap each wire nut with electrical tape for extra security.
5. 5. Attach the L-bar arm and shade: Slide the L-bar arm onto the backplate studs and tighten the Torx screws. Then attach the shade or globe according to the fixture design — usually a simple twist or set screw. Common mistake: forcing the shade can crack glass; align threads or slots before tightening. If the shade does not sit flush, check for debris or misalignment.
6. 6. Restore power and test: Turn the circuit breaker back on. Flip the wall switch to confirm the light works. If it does not, turn off power again and recheck wire connections. Common mistake: a loose wire nut can cause intermittent flickering. If the light flickers, tighten wire connections and ensure the bulb is fully seated.

Product facts

• L-BAR / LINEAR: The L-BAR / LINEAR is made from solid metal with a diamond-cut, linear knurl pattern and includes a precision milled base, backplate, and Torx screw detailing. The solid metal construction and precision backplate ensure a stable mount, while the Torx screws provide a secure, tamper-resistant fix — use the correct bit to avoid stripping.
