How to Install a New Light Point: A DIY Guide 2026

During a renovation or when changing the use of a room, you might find yourself needing to add a new light point. To install a new light point, you need to work on the existing electrical system, adding a branch to adequately serve the new area. We solve the problem of the new light point with an external channel system, which is easy and quick to apply, creating the new system starting from the nearest junction box.

If you also want an additional socket, evaluate the current intensity (amps) you need and make sure the cross-section of the system's conductors can handle it, then size the wires you are adding. For a socket to power a power tool, conductors with a cross-section of no less than 2.5 mm² are required; for lighting, 1.5 mm² is sufficient. You can fix the channels, lay the conductors inside them, and prepare the connections without cutting power to the system. You only do this before connecting the new section to the existing one in the junction box. For a complete selection of wiring and components, explore our Home Improvement collection.

How to Create a New Light Point

To create a new light point, you must start from the junction box and figure out how to connect a switch. You need to run 3 wires to the lamp holder and 5 to the switch and socket box. For safety, leave the 3 wires that go to the existing system for last. To join the wires, strip about 1.5 cm, twist the ones to be joined together, hold them in place with a few turns of electrical tape, and secure them with insulating caps. Start making the connections in the socket box. Three wires must reach the power socket: one gray wire that carries the...

Step-by-Step Installation

First, ensure you have all your materials ready. Mount the channels along the wall, using a level to keep them straight. Secure them with the expansion plugs and screws. Lay the wires inside the channels, leaving enough slack at each end for connections. For outdoor or garage installations, consider durable options from our Garden Supplies range.

How to Install External Channels

External channels are a clean and efficient solution for adding wiring without breaking into walls. Measure and cut the channel sticks to size. Attach the 90° curves at corners. Use the tube collars to secure the channels every 30-40 cm. Feed the wires through, then snap the covers on. This method works perfectly for adding a light point in a workshop or basement.

Tips for Buying a Light Point

When purchasing components, ensure the switch and socket are rated for the intended load. For outdoor installations, always use weatherproof fittings. A dimmer switch can add ambiance to a living area. Pair your new lighting with stylish Wall Decor to enhance the room's aesthetic. For the bedroom, consider matching your light point with a new Nightstand for a cohesive look.

Frequently Asked Questions (FAQ)

1. Can I install a new light point without cutting the main power?

You can prepare the channels and lay the wires without cutting power, but you must turn off the main breaker before making the final connections in the junction box. Always use insulated tools and test the circuit with a voltage tester. For added safety, equip your home with reliable Home Improvement safety gear.

2. What wire gauge do I need for a new light point?

For standard lighting circuits, 1.5 mm² wire is sufficient. If you are adding a socket as well, use 2.5 mm² wire to handle higher loads. Always check your local electrical codes. A well-lit workspace is essential; browse Lighting options for task lamps and overhead fixtures.

3. How do I connect the switch to the new light point?

Run a live wire (usually brown or gray) from the junction box to the switch, then a switched live wire from the switch to the lamp holder. The neutral wire (blue) goes directly from the junction box to the lamp holder. The ground wire (yellow/green) connects to the lamp holder's earth terminal. For a complete setup, consider a TV Entertainment Furniture unit with built-in cable management for your media room.

4. Can I use this method for an outdoor light point?

Yes, but you must use weatherproof channels, outdoor-rated cables, and sealed junction boxes. Outdoor lighting enhances security and curb appeal. Explore our Outdoor Lighting and Outdoor Decor collections for durable and stylish options.

5. What if I don't have a nearby junction box?

If no junction box is nearby, you may need to run a new circuit from the main panel, which is a more complex job best left to a licensed electrician. However, for simple additions, you can often tap into an existing socket or light fixture. For organizing your tools and supplies, a Storage Bench can keep your workspace tidy.
