Installing LED strip lighting

LED strips are cheap to buy and easy to stick up. Making them last, and reaching the driver later, is the part that needs planning.

LED strip lighting is used in ceiling coves, under kitchen cabinets, inside wardrobes, behind headboards and along stairs. Most strips run at low voltage and need a driver — a power supply that converts mains voltage. The driver gets warm, eventually fails, and must be reachable for replacement. Hiding it permanently behind plaster or fixed joinery is a common mistake.

Installation guides cover what a fitting or appliance needs from the electrics before it goes on the wall or ceiling.

Long runs can lose voltage along their length, showing as dimmer or colour-shifted light at the far end; feeding the strip from both ends or in sections solves it. Strips also produce heat, so mounting them in aluminium profiles helps them last and gives a cleaner line of light.

01In short

The points that matter most

  • Keep the driver reachable

    Drivers fail eventually and must be replaceable.

  • Watch long runs

    Voltage drop makes far ends dimmer.

  • Use profiles

    Aluminium channels manage heat and diffuse light.

02Detail

What a good installation includes

  • Driver sizing and position

    Drivers rated with headroom for the strip load and placed in an accessible, ventilated spot.

  • Feeding long runs

    Power injected at intervals or both ends to keep brightness even.

  • Mounting

    Profiles and diffusers fixed properly rather than relying on the adhesive tape alone.

  • Control

    Dimming and switching chosen to suit the driver type.

03Checklist

Before installation

  • Plan driver access

    An access panel or removable joinery panel.

  • Measure the runs

    Total length decides driver size and feed points.

  • Choose colour and brightness

    Consistently across the room.

04Questions

Questions people ask

Why does my LED strip fade at the end?
Voltage drop along a long run; feeding it from more than one point fixes it.
Can LED strips be dimmed?
With a dimmable driver and a compatible dimmer or controller.
Why did the strip stop working after a few months?
Overheating, an undersized driver or poor connections are common causes.
Are LED strips safe in bathrooms?
Only products rated for the location, with drivers placed outside wet zones.
