Cable for lighting fixtures

Start by matching the cable to your fixture's power type and installation. Identify whether your setup is mains-powered (230V AC) or low-voltage (12V DC) for LED strips. Choose an appropriate conductor size based on wattage and distance to minimize voltage drop. Pick insulation suitable for indoor or outdoor use and ensure the connector type fits your fixture's terminals. For Nordic pendant lights, ensure the cable length suits ceiling height and uses proper strain relief.

Voltage rating and current-carrying capacity are the most complex attributes for a cable used with lighting fixtures. Calculate current by dividing the fixture’s wattage by the supply voltage, then choose a cable with a gauge that safely carries that current over your run. For LED strips, also account for driver current and potential voltage drop along the length. Using a cable with an insufficient gauge can cause overheating, voltage drop, or dimming.

For a home setting, pick a simple mains-rated cable with a secure earth connection for a pendant light. In commercial or outdoor installations, plan for weather-rated or IP-rated cables and consider longer runs with appropriate drivers. LED strip setups typically require low-voltage cables matched to the driver and kit requirements. This approach ensures safety and reliable performance across different environments.

Verify that the cable’s voltage and current ratings match your fixture and that the insulation is intact. Use proper strain relief and secure connections, avoiding sharp bends that could damage insulation. If used indoors vs outdoors, select cables rated for the environment and keep power and data cables separated where needed. Regularly inspect for wear and replace damaged cables promptly.

Nordic is a solid option for pendant lights, offering reliable power cords and adjustable lengths. For LED strip installations, generic brands provide flexible, color-matched lightning-cables and power cables. Be cautious with non-lighting cables such as RG59 CCTV cables offered as power cables, since they are designed for video signals and not for lighting. Choosing purpose-built lighting cables helps safety and performance.

Confirm the voltage rating and current rating match your fixture before wiring. Inspect insulation integrity and ensure connectors are clean and secure. Plan routes to avoid moisture and heat sources, and ensure in-wall or outdoor use meets installation standards. If using LED strips with drivers, verify driver compatibility and capacity.
