Connecting 4-Section LED Ceiling Lamp with 3 Cables & 2 Switches: Wiring Blue & Brown Wires

dkristofer 7374 18
Best answers

How do I wire a 4-section ceiling lamp with blue and brown wires to a double switch so that two sections light on each key?

You cannot wire this lamp so that two sections are controlled by one key and the other two by the second key; the fixture is designed to work as one circuit, so all 4 bulbs light together on a single switch [#16675318][#16675369] To use a double switch, the installation must be modified and the supply cable replaced with 4x1.5 mm² [#16675914] The thread also notes that the ceiling wire colors may be misleading, so the conductors should be checked rather than trusted by color alone [#16675974] If there is no PE present at the ceiling, a different class II luminaire with double/reinforced insulation is needed, or an electrician should verify the wiring and continuity [#16676672]

    Hello, If someone would help me and indicate how to connect this ceiling, 3 cables come out of the ceiling, switch 2, it is best for me to light on one switch 2 middle and on the other switch 2 side, or how it goes in turn 2 and 2, nowhere I can not find and somehow marked or numbered as to what it would be cool, if anyone can help, please, I am still mixed up with these blue and brown cables.

    Do you have a single or double switch? Give me a picture.
    This lamp probably the entire network at the same time because the white cube has two power cords.

    Phase and zero so you control a single key switch.
    Inside, all 4 lamps are connected in series - they light up simultaneously.

    I want 2 keys to light 2 and 2 as I described well and these are brown and blue cables and then mixed with those thin red and brown thick

    Added after 1 [minutes]:

    sorki with red it is black and all thin ones

    Added after 3 [minutes]:

    I think there is a possibility of such connection, but you probably need to mix something in these cables

    Added after 3 [minutes]:

    So it would only be connected to this cube which is blue and brown and nothing can be mixed up so that it shines after 2 LEDs. There must be a way

    Installation does not allow it, the lamp does not allow it, there is no such option.

    Thank you very much for the information, but I am disappointed because I asked when buying in Castorama at the lighting stand and they said it was possible.
    I will ask again, and if this lamp can be connected so that they have 2 leds lit, here are but G9 bulbs 4 pcs.

    This brown cable probably came out of the brown ones because I haven't seen it before.

    Not probably and certainly. The fitting is damaged in this condition. Under these black heat shrinks is a crimp terminal, which is probably badly crimped. Cover for complaint.

    By the way, with this luminaire you can't do "two" without wiring modification.

    Well, there is no converter here because the halides are 230V only you need to mix the cables differently and maybe someone knows how to do it. Thank you for your interest in my case

    Only you are not allowed by the electrical installation in the apartment to use a candlestick switch (double).
    The only solution to use the above-mentioned switch is to replace the cable with 4x1.5 mm.

    No measurements can be done but there may not be protective, only L, L, N since the switch is double and the colors of the wires may be misleading.

    But in the wire from the ceiling there can only be L, N, PE so there is no right to be a double switch. If it exists, it must be replaced by a single one and the installation must be connected to a new house.

    OK and when can the double switch be used, if the ceiling has 4 cables?

    Just removing the switch will do nothing if you have no PE with the lamp in the ceiling. If this is the case then you can use another luminaire in insulation protection class 2, i.e. with double or reinforced insulation marked on the rating plate with the symbol:
    Connecting 4-Section LED Ceiling Lamp with 3 Cables & 2 Switches: Wiring Blue & Brown Wires
    This luminaire can be used without PE and the yellow-green ceiling cable with L is marked with a black or brown T-shirt ...
    However, someone who can check the continuity of the cables should get on with it.

Topic summary

✨ The discussion revolves around the wiring of a 4-section LED ceiling lamp with three cables and two switches. The user seeks guidance on how to connect the blue and brown wires to achieve independent control of two sections of the lamp from two switches. Responses indicate that the lamp is designed to light all sections simultaneously unless modifications are made. Several users suggest that the current wiring setup may not support the desired functionality without changing the wiring configuration or using a different type of switch. Concerns about the integrity of the wiring and the necessity of a protective earth (PE) connection are also raised, with recommendations for using luminaires with double insulation if PE is absent. Ultimately, the user reports successful connection after following the advice provided.

FAQ

TL;DR: With only 3 conductors at the ceiling, you get 1 circuit; two‑gang 2+2 control needs 4×1.5 mm². “The only solution… replace the cable with 4×1.5 mm.” [Elektroda, rtvserwisant, post #16675914]

Why it matters: This FAQ helps DIYers decide if their 4‑lamp ceiling light can be split 2+2 and wired safely with two switches.

Quick Facts

Can I wire two switches to control 2+2 lamps when only 3 wires come from the ceiling?

No. A 3‑core drop (L, N, PE) supports one switched circuit. To control two groups you need a new 4×1.5 mm² cable and a compatible fitting. “The only solution… replace the cable with 4×1.5 mm.” [Elektroda, rtvserwisant, post #16675914]

Why won’t my two‑gang switch work with three ceiling conductors?

Because the three cores are L, N, and PE. A two‑gang needs two separate switched lives, plus neutral and protective earth. Replace the two‑gang with a single switch or re‑cable appropriately. [Elektroda, rtvserwisant, post #16675992]

Does the lamp itself allow splitting into 2+2?

Often no. Some luminaires link all sections internally, so all four light together. “Installation does not allow it, the lamp does not allow it.” Check the lamp’s terminals before planning. [Elektroda, kozi966, post #16675369]

What do the blue and brown wires mean in this context?

Brown is live (phase) and blue is neutral in many EU fixtures. With a single switched live, all lamp sections energize together. The post shows phase and neutral feeding the lamp simultaneously. [Elektroda, kindlar, post #16675318]

My fitting has four G9 bulbs. Do they need a driver?

If they are 230 V G9 halogens or mains‑rated LEDs, no external driver is used. They connect directly to the mains through the lamp’s terminals. Verify bulb type before wiring. [Elektroda, dkristofer, post #16675672]

How do I safely get 2+2 control on a 4‑lamp ceiling light?

Ensure your ceiling drop has two switched lives by running 4×1.5 mm². Use a two‑gang switch and a luminaire with separate live feeds for each pair. This enables independent 2+2 switching. [Elektroda, rtvserwisant, post #16675914]

What if my ceiling has no PE (earth)?

Use a Class II (double‑insulated) luminaire marked with the double‑square symbol, or have an electrician verify continuity and safety. Do not ignore missing PE on Class I metal fittings. [Elektroda, Jacek Rutkowski, post #16676672]

How can I tell if all four lamps are internally linked?

If only two terminals (L and N) exist in the lamp block and no separate feeds per section, it’s linked. The forum notes such lamps light all four together. [Elektroda, kindlar, post #16675318]

How‑To: verify what conductors you really have before wiring

  1. De‑energize the circuit and remove the ceiling rose or canopy.
  2. Identify cores and test with a meter; colors can mislead.
  3. Confirm presence of PE and count switched lives before choosing a switch. [Elektroda, kindlar, post #16675974]

Is a loose brown lead under heat‑shrink a safety issue?

Yes. That indicates a failed crimp connection. The fixture is considered damaged and should be returned or properly repaired before use to avoid overheating. [Elektroda, kozi966, post #16675667]

What is a two‑gang (double) switch?

It is a wall switch with two independent rockers controlling two separate lighting circuits. To use both gangs at one point, your drop must provide two switched lives. The cited post discusses the required cable. [Elektroda, rtvserwisant, post #16675914]

Edge case: My ceiling cable might be L, L, N (no PE). What then?

Colors can mislead. Measure first. Some setups route two lives and a neutral, leaving no protective earth at the point. Treat this as a limitation and plan accordingly. [Elektroda, kindlar, post #16675974]

After wiring, all four lamps light at once. Is that normal?

Yes for fixtures wired with a single live and neutral across all sections. They are internally linked, so all four illuminate together by design. [Elektroda, kindlar, post #16675318]

What symbol confirms a Class II (double‑insulated) light?

Look for two concentric squares on the rating label. This means enhanced insulation and no PE connection is required for the luminaire. [Elektroda, Jacek Rutkowski, post #16676672]
