What you also need

LED flex runs on 12V DC, not mains. To complete the installation you will need:

A 12V constant-voltage driver — this strip draws 4.8W per metre, so a 5m run needs roughly 29W once you allow 20% headroom.
An aluminium profile with diffuser — protects the strip, helps it run cool and softens the light.
Connectors — solderless joiners for quick runs, or we can solder and prep the run for you before collection.

Typical applications

Kitchen plinths, under-cabinet and worktop lighting
Coving, pelmets and cove lighting
Wardrobes, shelving and display cabinets
Stairs, handrails and corridor accent lighting
