How do I add under-cabinet lighting to my kitchen without opening the walls?

You can add under-cabinet kitchen lighting without opening walls using plug-in LED strip lights or puck lights connected to existing countertop outlets — no electrical work required for the basic approach.

Easiest option: Plug-in LED strip lights

LED light strips with adhesive backing are the simplest under-cabinet lighting solution:

• Stick the LED strip to the underside of the cabinet, toward the front edge (hides the strip from view)


• Run the low-profile power cord down the inside of the cabinet, through the back panel, or along the wall to a countertop outlet


• Use a cord channel or paintable cord cover for a clean look


• Cost: $30-$80 for a complete kitchen run


• No electrician needed, no permit needed

Better option: Hardwired LED puck lights or light bars

For a cleaner, more permanent installation:

• LED puck lights mount to the underside of cabinets with screws


• Light bars provide continuous, even illumination (better than individual pucks)


• A licensed electrician runs wire from a nearby switch or outlet through the wall to a new switch location


• The switch can be placed inside a cabinet or on the wall — some electricians can fish wire without opening walls using flexible drill bits


• Cost: $500-$1,200 installed


• Requires a licensed electrician and TSANB permit

Wireless options:

• Battery-powered LED puck lights: Stick-on installation, rechargeable via USB. No wiring at all. Good for renters or minimal commitment. Cost: $20-$50 for a set


• Motion-activated under-cabinet lights: Turn on when you reach under the cabinet. Battery or rechargeable. $15-$40 per unit

Light temperature for kitchens:
Choose 3000-4000K (neutral white) for kitchen task lighting. The warm 2700K lights popular for living rooms make food preparation difficult — you need clear, bright light for chopping and cooking. Avoid cool 5000K+ which feels harsh and clinical.

NB kitchen considerations:

• Many older NB kitchens have limited outlets on countertops. If you have only 1-2 outlets, adding more before tackling under-cabinet lighting makes sense


• If you're planning a kitchen renovation, have the electrician rough in under-cabinet wiring while the walls are open — it's the cheapest time to add it


• CEC requires countertop outlets every 1.8 metres in kitchens. If your NB home doesn't meet this standard, upgrading outlets and adding under-cabinet lighting together is cost-effective

DIY tip for the plug-in approach: Run the cord inside the cabinet through a small hole drilled in the cabinet bottom near the back wall. This hides the cord completely while still plugging into a countertop outlet. Use a 1/2" spade bit and grommet for a clean finish.
