How to install LED strip lighting in a kitchen, wardrobe or home office

⚡ Installing LED Strip Lighting in a Kitchen, Wardrobe or Home Office

What is involved in installing LED strip lighting in a kitchen, wardrobe, or home office?

LED strip lighting is a practical way to add task lighting, ambient lighting and better visibility to kitchens, wardrobes and home offices. The job can range from a simple plug-in DIY setup to a more complex hardwired installation, and planning the power supply, mounting surface and cable routing is what makes the difference between a neat result and a short-lived one.

Electrical work in Australia must be performed by a licensed electrician. This guide is for understanding the process and selecting the right tools and materials. Where permanent wiring, new power outlets, transformers/drivers connected to fixed wiring, or switchboard alterations are involved, the work must comply with AS/NZS 3000 and be carried out by a licensed electrician.

Step-by-Step Guide

Step 1: Plan the lighting layout

Decide what the strip is meant to do: task lighting under overhead cupboards, shelf lighting in a wardrobe, or soft backlighting around a desk or monitor area.

Measure each run in millimetres and note where the power source will be located. Common placements include:

Choose whether the installation will be:

For kitchens, under-cabinet front-edge positioning usually throws light onto the benchtop more effectively than mounting at the rear.

Step 2: Select the correct LED strip and driver

Choose a strip with suitable brightness, colour temperature and ingress protection.

As a guide:

For task lighting, look for higher output strips, typically 10–15 W/m or more depending on the diffuser and mounting height. For wardrobes and feature lighting, lower output may be sufficient.

Match the driver to:

Example:

If the strip is 14.4 W/m and the total run is 4 m, total load is 57.6 W. Select a driver with headroom, such as 75W or higher, subject to manufacturer recommendations.

💡 Pro tip: 24V DC strip is often better for longer runs because it reduces voltage drop compared to 12V DC.

Step 3: Check cut lengths and run limitations

LED strip can only be cut at manufacturer-marked cut points. Before buying, confirm:

Long runs may need:

This is especially important in kitchens with long benchtops or large walk-in wardrobes.

Step 4: Prepare the mounting surface

Clean the installation area thoroughly. Dust, grease, laminate residue and cabinet polish are common reasons strips peel away over time.

Use isopropyl alcohol on:

If the surface is rough, textured or prone to heat, use aluminium channel rather than relying on adhesive backing alone.

💡 Pro tip: In kitchens, aluminium channel improves heat dissipation and gives a straighter, more professional finish with a diffuser that softens LED spotting.

Step 5: Mark out the channel and cable entry points

Use a tape measure and level to mark where the strip or channel will sit.

Plan for:

In wardrobes, placing vertical strips just behind the door line helps avoid direct glare. In home offices, conceal the strip behind a front lip or shelf edge for a softer reflected light.

Step 6: Test fit the strip, driver and controls

Before drilling or sticking anything permanently:

Check for:

This step helps you catch polarity errors, faulty connectors or an undersized driver before installation.

Step 7: Install the aluminium channel or mounting base

Fix the channel securely with screws or manufacturer clips. Adhesive-only mounting is often unreliable in kitchens due to heat and grease.

Cut channel neatly to length and deburr any sharp edges. Fit it straight and tight to the cabinet or panel.

For corners:

Do not crush low-voltage cables behind channels or fixings.

Step 8: Cut and install the LED strip

Cut the LED strip only at the marked cut points. Peel back the adhesive and press the strip evenly into the channel.

Avoid:

If using joiners, ensure they are fully seated and polarity is correct. Fit the diffuser after confirming the strip is straight and operating properly.

Step 9: Route and secure the low-voltage cabling

Run the extra-low-voltage cable neatly to the driver location. Use cable clips, adhesive mounts or concealed drilling through cabinet panels where appropriate.

Keep the cabling:

For visible runs inside wardrobes or offices, match cable colour to cabinetry where possible for a cleaner look.

Step 10: Install the driver and connect power

For a plug-in DIY system, place the driver in a dry, ventilated and accessible location near a socket outlet. Do not bury it inside sealed cavities or inaccessible voids.

For hardwired systems, a licensed electrician must install and connect the driver to fixed wiring, typically supplied from a lighting or socket circuit depending on the design. This fixed wiring may involve 1.5mm² TPS or 2.5mm² TPS, selected by the electrician in accordance with circuit protection, installation conditions and AS/NZS 3000.

Wardrobe and office installations may also use:

Make sure all components are compatible with each other.

Step 11: Final testing and adjustment

Turn the system on and verify:

Check at night as well as during the day. In kitchens, confirm the strip does not reflect harshly off glossy splashbacks. In home offices, check that it does not cause screen glare.

Step 12: Finish, label and maintain

Tidy all visible cables and fit any diffusers, end caps and trim pieces.

Keep a record of:

This makes future repairs or extensions much easier.

Clean diffusers periodically, especially in kitchens where grease and dust can reduce light output over time.

⚠️ Safety

🔒 Licensing

Plug-in LED strip kits can be suitable for homeowners where no fixed wiring is altered. However, any permanent electrical wiring work in Australia must be completed by a licensed electrician in accordance with state or territory laws and AS/NZS 3000. If your project involves concealed cabling, a new switched feed, a hardwired driver, integration with existing lighting circuits, or work near a switchboard, engage a licensed electrician.
