Learn how to safely install the Block Lamp Electrical Part from Design House Stockholm. Follow these step-by-step instructions for a secure DIY lamp assembly.

Quick answer

Installing the Block Lamp Electrical Part is straightforward if you follow the correct wiring order and safety checks. Always disconnect power before starting and verify the E14 bulb is seated properly.

Before you start: what the electrical part includes

The Block Lamp Electrical Part from Design House Stockholm is a complete spare component designed for the iconic Block Lamp. It comes with an incandescent bulb, an E14 fitting, and a black textile cord. You can choose between Black EU Cable, Black US Cable, or White EU Cable versions depending on your region and preference.

Because this is a replacement part rather than a full lamp kit, you will need to attach it to your existing Block Lamp base. The wiring is pre-assembled inside the part, so you only need to connect the cord to your lamp holder and secure the bulb.

Common safety pitfalls to avoid

One frequent mistake is forcing the bulb into the fitting. The E14 socket is designed for a gentle twist; if it does not slide in easily, check that you have the correct bulb type. Another issue is overtightening the cord connector, which can damage the textile insulation. Finally, never plug the lamp in before the electrical part is fully seated and the bulb is secured.

Step-by-step installation guide

1. Disconnect power and prepare your workspace: Unplug the lamp from the wall outlet. Lay the Block Lamp base on a clean, dry surface. Have the electrical part, bulb, and a small flathead screwdriver ready. Never work on a lamp that is plugged in.
2. Attach the electrical part to the lamp base: Insert the threaded neck of the electrical part into the hole on the Block Lamp base. From underneath, screw the retaining ring (included with the part) onto the neck until it is snug. Do not overtighten. If the ring is cross-threaded, the part may sit crooked. Back it out and try again.
3. Connect the cord to the lamp holder: Open the lamp holder by unscrewing the cap. Feed the black textile cord through the cap, then strip about 1/2 inch of insulation from the two wires. Connect the live wire (usually brown) to the center terminal and the neutral wire (blue) to the outer terminal. Tighten the screws firmly. Mixing up live and neutral wires will not cause a short, but it leaves the lamp shell energized if touched. Double-check the markings.
4. Secure the bulb: Screw the incandescent bulb into the E14 socket until it is hand-tight. Do not use tools or over-tighten, as this can crack the glass or damage the socket. If the bulb does not screw in easily, check that you are using the correct E14 bulb and that the socket is clean.
5. Test the lamp: Plug the lamp into a grounded outlet and turn it on. The bulb should light immediately. If it does not, unplug the lamp and check the bulb seating and wire connections. If the bulb flickers, the wire connections may be loose. Turn off power and re-tighten the terminal screws.
