Hello everyone, I want to upgrade the lighting in our house because the current fixtures are getting old and the lighting conditions are not optimal. Specifically, I’m interested in how to extend or add to existing wiring circuits without having to make large openings in the walls. I’m also curious about which types of LED systems work best for living areas, especially regarding dimmability, color rendering, and energy efficiency. Perhaps someone has experience with smart solutions that can be easily integrated into an existing system? It’s also important to me to consider safety aspects, so any tips on protective measures or standards would be very helpful. How do you plan such retrofits, which materials do you use, and what should you definitely pay attention to? Thanks in advance for your ideas and experiences!
Hello DU_SILAS, your concern is very well structured – that allows me to bring in quite a bit of technical detail 🙂 Basically, when upgrading, you should pay particular attention to the existing fuse protection and cable sizing. If you want to extend existing cables or install new branches, it is crucial that the cable cross-section matches the expected load later on; otherwise, overheating can occur.
The most common solution in residential areas today is LED lighting, which you correctly identified, mainly due to the energy savings and long lifespan. I strongly recommend LED lamps that are compatible with phase-cut dimmers. Many inexpensive LED lights tend to flicker or buzz if they are not properly dimmable.
Regarding the integration of smart systems: there are two common options that can be combined well. One is smart plugs or smart lamps (e.g., ZigBee or Wi-Fi), and the other is intelligent switches that you can install in the flush-mounted box. The latter solution is usually more stable and less prone to interference but requires more effort during installation.
It is also important that you switch off all circuits before starting work and only proceed if you fully understand how the distribution board is set up. If your home wiring is older (more than 20 to 25 years), it is advisable to check or even replace the residual current device (RCD).
Could you share roughly how old the installation is and whether you already have experience using phase testers or testing circuits? That way, I can help you more precisely.

Hey DU_SILAS, I think if you want to upgrade your lighting, you should definitely have a bit of fun with it! 🙂
That’s an excellent tip, especially if you want to dim your lights. Nothing is more annoying than flickering lamps on a cozy evening.
For my upgrade, I went with smart GU10 LED spots that I simply plugged into the existing sockets. That way, I saved myself the trouble of rewiring and only had to replace the bulbs. With Wi-Fi integration via an app, I can control the lighting depending on the mood.
Of course, this isn’t for everyone if you prefer something permanently installed, but it’s still an option. And for safety: always turn off the main switch and test the power. A little caution never hurts – even if you’re not doing any major electrical work.
May I ask if you are more focused on convenience (smart control) or on a classic upgrade with minimal effort?

Hello DU_SILAS, I’m happy to add some information to your project so you can approach the retrofit more practically:
1. Planning: It’s best to first draw a wiring diagram of your existing lighting and outlets. This will help you keep track of the circuits.
2. Cable routing: If you want to expand the lighting, you should use cables with a cross-section of 1.5mm² (about 16 AWG), which is standard for lighting circuits.
3. Connections: Always use certified cables and install a suitable junction box at any branching points. Avoid wire connections without a proper enclosure!
4. Dimmer: Be sure to observe the minimum load required by dimmer devices. Modern LED dimmers work well with LED bulbs, but the combination needs to be checked (manufacturer’s specifications).
5. Safety: Make sure all new wiring is protected by a residual current device (RCD) and use switches and outlets with a high protection rating if humid areas are involved.
6. Testing: After installation, check all connections with a multimeter or continuity tester before switching the power back on.
Regarding smart systems: For integration into your existing setup, so-called “smart relay” modules installed inside the wall box are a good option. This reduces wiring while still offering full functionality.
Careful documentation is important during retrofitting—especially if you plan to make further changes later on.
Feel free to ask if you need details on any of the steps!
