Shedding Light on Lamp Rewiring


Lamps are more than just functional lighting fixtures; they can be cherished pieces of decor that add warmth and character to any room. Many times, though, when shopping estate sales, flea markets or thrift stores, the wiring is old and unsafe, or visibly damaged. I’ve had more than a couple exciting moments while ‘testing’ to see if a lamp or light fixture is in working condition. I recently got this great bronze bamboo-style floor lamp at an estate sale, but the plug was missing.

Even your own lamp may, over time, wear out or become damaged, posing safety hazards and diminishing their functionality. Fear not! With a little know-how and some basic tools, rewiring a lamp can breathe new life into your beloved fixture. In this blog post, we'll walk you through the process of rewiring a lamp, from removing the old wiring to installing the new, and discuss why it's a worthwhile endeavor.

Removing the Old Wiring

The first step in rewiring a lamp is to safely remove the old wiring. Start by unplugging the lamp and removing the shade and lightbulb. If the lamp has a harp, squeeze the neck to release it from the base.

Next, carefully examine the lamp to locate the point where the cord enters the base. It is usually very obvious. In most cases, you'll find a small metal cap, known as a "knob," that secures the cord in place. Sometimes it just runs right up the bottom of the base. If it is held in place by a knob, unscrew the knob and set it aside.

Once the knob is removed, gently pull the cord out of the base, taking care not to damage any other components. You may need to loosen screws or clips holding the cord in place inside the base. Usually, this will require you to expose the point where the wires connect to the bottom of the bulb socket. Once the old wiring is completely removed, discard it responsibly, ensuring it doesn't pose a hazard to curious hands or pets.

Putting in the New Wiring

With the old wiring out of the way, it's time to install the new wiring. Start by threading the new cord through the base of the lamp, following the same path as the old cord. I used a string through the base of the lamp to help me pull the new cord through.

Be sure to leave a few inches of excess cord at the base to allow for easy connection to the lamp socket.

Next, strip the insulation from the ends of the new cord to expose the wires inside. You'll typically find two wires: one smooth and one ribbed or ridged. These wires correspond to the "hot" and "neutral" connections in the lamp socket. Attach the smooth wire to the brass screw terminal and the ribbed wire to the silver screw terminal, securing them in place with a screwdriver.

Once the wires are securely connected, reassemble the lamp, making sure everything is properly aligned and tightened. Replace the shade and lightbulb, and plug the lamp back in to test that it's working correctly.

Why Rewire a Lamp?

You might be wondering, why bother going through the trouble of rewiring a lamp when you could just buy a new one? There are several reasons why rewiring a lamp is a worthwhile endeavor:

  1. Safety: Old or damaged wiring can pose a fire hazard, putting your home and loved ones at risk. By rewiring a lamp, you ensure that it meets modern safety standards and functions reliably.
  2. Cost-Effective: Rewiring a lamp is often more cost-effective than purchasing a new one, especially if you already own a lamp with sentimental or aesthetic value.
  3. Environmental Impact: By refurbishing and reusing existing fixtures, you reduce the demand for new materials and contribute to a more sustainable lifestyle.
  4. Personalization: Rewiring a lamp gives you the opportunity to customize its design and functionality to better suit your needs and style preferences.
  5. It's easy: The lamp kit I bought cost $12 and included extra parts and instructions.

In conclusion, rewiring a lamp is a simple yet rewarding DIY project that can extend the life of your favorite fixtures or restore a great thrift store purchase while ensuring they remain safe and functional for years to come. So, the next time you find yourself with a flickering or faulty lamp, don't toss it out – roll up your sleeves and give it a new lease on life with a fresh set of wires. Your home (and your wallet) will thank you!
