How to Cut and Join LED Strip Lights
Cutting strips to length and connecting runs together correctly is one of the most important parts of any LED installation — and one of the most common sources of problems.
Where to cut
Cut only at designated cut marks — indicated by a scissor icon or dotted line, printed every 25–50mm along the strip. Use sharp scissors and make a clean, perpendicular cut across the full width of the strip.
Interconnecting leads
Solderless connectors that lock onto cut strip ends and allow runs to be extended or routed around obstacles. Available in 1.5m and 2.5m lengths. Always use the connector specified for your strip range — not all connectors are interchangeable between ranges.
Corner connectors
For 90-degree turns within the same plane — for example, running a strip around the corner of a cove. Use the dedicated corner connector for your strip range to maintain a clean, low-resistance connection through the bend.
Joining clips
For joining two strip ends together — for example, after cutting a strip into two sections. Align cut ends carefully, press into the clip, and lock. Always check polarity before powering: positive to positive, negative to negative.
Test
Always test all connections before fitting profiles, diffusers, or finishing surfaces. Far easier to re-seat a connector or check polarity at this stage than after the installation is complete.
What not to do
- Cut between cut marks
- Use connectors from a different strip range
- Leave loose or temporary connections in a finished installation
What you'll need
- Sharp scissors
- Interconnecting leads (correct range)
- Corner connectors (if needed)
- Joining clips (if needed)
