Connectable tree lights setup

Connectable tree lighting is a great way to illuminate your garden or outdoor space—especially during the holidays or for special occasions. The process is simple, but following the correct steps ensures a safe, reliable, and attractive result. Below, we guide you through the installation step by step, with notes on planning, connection and how many metres you’ll need.

Tools you’ll need

Before you begin, gather the essentials. You may not need everything, but having them ready helps.

- Voltage tester (for hardwired connections only)
- Outdoor-rated extension lead (if needed)
- Ladder and soft work gloves
- Cable ties / reusable plant ties / hook-and-loop straps
- Weatherproof adapters, couplers and end caps (per system)
- Optional: timer, dusk sensor or smart plug

Step-by-step installation guide

1. Check the materials and lights

Confirm you have everything: the connectable tree lights, plugs/adapters, any extension leads and the required couplers. Read the manual to verify compatibility and maximum connectable length per power supply.

2. Place the lights on the tree

Start wrapping the cable gently around the trunk and branches. Spread the bulbs evenly and avoid pulling the cable tight—this prevents damage and keeps the look neat. For longer runs, thread the cable between branches to achieve an even light distribution.

3. Connect the cables

If you have multiple sets, join them using the system’s connectable plugs. Push connections fully home and lock any collars so there are no loose joints that could cause poor contact or interruptions.

4. Connect to the power source

Attach the lighting chain to a suitable power source. Use an outdoor socket or a weatherproof extension lead if the socket is further away. Always use the correct adapter/driver and ensure the supply voltage matches the product specifications. Keep connections off the ground and protected from standing water.

5. Test the lighting

Switch on the system and check that all sections illuminate. Adjust the position of the lights for an even appearance. This is a good time to add a timer or smart plug for automatic on/off control.

How many metres of tree lighting do I need?

Not sure how much to order? Use the guideline below for an average tree. If your tree is particularly wide or has many branches, consider ordering a little extra.

Professional quality

Thanks to robust, outdoor-rated components, professional tree lighting can remain in the tree even after the festive season. That saves installation time, takedown time and cost each year—just reconnect power when needed.

Safety & best practices

- Use outdoor-rated products (IP44+; higher if more exposed).
- Keep connectors off the ground and protect from standing water.
- Observe the system’s maximum connectable length per power supply.
- Use a residual-current device (RCD) protected circuit for outdoor sockets.
- If hardwiring to 230V, switch off power and follow local regulations—or consult a qualified electrician.
