Safety First: Working with Electricity
Critical Safety Rules:
- • Turn off power at the circuit breaker, not just the switch
- • Test wires with a voltage tester before touching them
- • Never work on live wires
- • If you're uncomfortable with electrical work, hire an electrician
- • Verify ground wires are properly connected
Tools You'll Need:
- •Non-contact voltage tester
- •Wire stripper
- •Screwdriver set
- •Wire nuts (various sizes)
- •Drill with bits
- •Ladder or step stool
- •Electrical tape
- •Needle-nose pliers
Understanding Kitchen Lighting Layers
Great kitchen lighting uses three layers that work together. You'll likely be installing fixtures from each category.
1Ambient (General) Lighting
Overall illumination for the entire room:
- •Recessed ceiling lights (cans)
- •Flush or semi-flush ceiling fixtures
- •Track lighting
2Task Lighting
Focused light for specific work areas:
- •Under-cabinet LED strips
- •Puck lights under cabinets
- •Recessed lights over sink or range
3Accent (Decorative) Lighting
Adds style and highlights features:
- •Pendant lights over island
- •Chandelier over dining area
- •Cabinet toe-kick lighting
Installation Step-by-Step
1. Install Recessed Can Lights
Recessed lights (also called can lights or downlights) provide ambient lighting. Most modern renovation-friendly cans are "remodel" style that install from below.
- •Verify power is off at the breaker and test with voltage tester
- •Pull electrical wire from the junction box through each can location
- •Connect wires to the can fixture: black to black (hot), white to white (neutral), ground to ground
- •Secure connections with wire nuts and wrap with electrical tape
- •Push the can housing up into the ceiling hole
- •Flip the mounting clips up to secure against the ceiling
- •Install the trim ring or integrated LED module per manufacturer instructions
Pro Tip: LED integrated recessed cans are easier to install than traditional cans that need separate bulbs and trim. They're also more energy-efficient and the light quality is better.
2. Hang Pendant Lights
Pendant lights over an island or peninsula add both task lighting and visual interest. Height matters—too high and they don't light the workspace, too low and they obstruct the view.
- •Turn off power and verify with voltage tester
- •Attach the mounting bracket to the ceiling junction box
- •Adjust the chain or cord to desired length (30-36 inches above counter is standard)
- •Feed wires through the canopy and connect: black to black, white to white, ground to ground
- •Tuck wires into the junction box and attach canopy to mounting bracket
- •Install bulb and attach shade, globe, or other decorative element
Pendant Height Guide:
- •Over island/peninsula: 30-36 inches above countertop
- •Over dining table: 30-34 inches above table surface
- •With seating: ensure pendants don't block sightlines when seated
- •High ceilings (9+ feet): can go slightly lower for drama
Common Mistake: Hanging pendants too high. They end up lighting the ceiling more than the work surface. Measure from the counter up, not from the ceiling down.
3. Install Under-Cabinet Lighting
Under-cabinet lights eliminate shadows on countertops and make food prep safer and easier. LED strips are the most popular choice for their low profile and even light distribution.
- •Plan layout—lights should run the full depth of the cabinet for even coverage
- •Mount LED strips or puck lights to the underside of wall cabinets
- •Position toward the front (not center) to light the work surface
- •Connect sections together if running multiple lights
- •Route wires to power source (hardwired junction box or plug-in transformer)
- •Secure wires with clips so they're not visible from the front
- •For plug-in systems, connect to transformer and plug into outlet
Under-Cabinet Lighting Options:
LED Strip Lights (Most Popular):
Thin, continuous light with no dark spots. Easy to install with adhesive backing. Linkable for long runs.
LED Puck Lights:
Individual round lights spaced every 8-12 inches. Create pools of light rather than continuous glow.
LED Light Bars:
Rigid bars that link together. More substantial than strips, easier to install than pucks.
Pro Tip: Install under-cabinet lights toward the front edge of the cabinet, not in the middle. This directs light onto the work surface instead of creating a bright line on the backsplash.
4. Install Additional Fixtures
Depending on your design, you might have other fixtures like a chandelier over a dining area, track lighting, or specialty accent lights.
General Fixture Installation Process:
- 1.Turn off power and verify it's off with voltage tester
- 2.Attach mounting bracket to junction box
- 3.Connect ground wire (bare or green) first for safety
- 4.Connect neutral wires (white to white)
- 5.Connect hot wires (black to black, or black to colored)
- 6.Secure all connections with wire nuts
- 7.Tuck wires into junction box and attach fixture to mounting bracket
- 8.Install bulbs and any decorative elements
5. Test All Lights and Switches
Before you finish, verify everything works correctly. This is your chance to catch any loose connections or switch wiring issues.
- •Turn power back on at the breaker
- •Test each switch to verify it controls the correct lights
- •Check that all bulbs are working
- •Test dimmer switches through their full range
- •Verify under-cabinet lights turn on/off properly
- •Look for any flickering or buzzing (indicates a wiring problem)
- •Make sure no fixtures are loose or improperly seated
Success Indicator: If all lights work correctly, switches control the right fixtures, and nothing flickers or buzzes, you've successfully installed your kitchen lighting. Take a moment at night to appreciate how the layered lighting transforms the space.
Common Issues and Solutions
Light doesn't turn on
Solutions: Check that power is on at the breaker. Verify the bulb is installed correctly and not burned out. Test the switch with a voltage tester. Check that all wire connections are secure—loose wire nut connections are a common culprit.
Light flickers or buzzes
Solutions: Usually means incompatible dimmer and bulb. LED bulbs need LED-compatible dimmers. Try a different bulb first. If that doesn't work, the dimmer may need replacing. Buzzing can also indicate a loose connection—turn off power and check wire nuts.
Recessed light won't stay in ceiling
Solutions: The mounting clips may not be engaging properly. Remove the can and make sure clips are in the open position before inserting. Push can firmly into hole, then flip clips. If ceiling is too thin, you may need different clips or to add blocking.
Under-cabinet lights have dark spots
Solutions: LED strips need to run continuously—don't leave gaps. If using puck lights, they should be spaced no more than 8-12 inches apart. Consider switching to LED strip lights for more even coverage.
Frequently Asked Questions
Can I install light fixtures myself or do I need an electrician?
If you have basic electrical knowledge and the wiring is already in place, you can install most light fixtures yourself. Replacing an existing fixture is straightforward. However, hire an electrician if you need to: run new circuits, add junction boxes, install dimmer switches for the first time, or if you're uncomfortable working with electrical wiring. When in doubt, spend the money for safety and code compliance.
How many recessed lights do I need in my kitchen?
A general rule is one recessed light per 25-30 square feet for ambient lighting. For task lighting over work areas, space lights 18-24 inches from the cabinet face and 3-4 feet apart. Most kitchens benefit from layered lighting: recessed cans for general light, under-cabinet for task lighting, and pendants for accent lighting. Err on the side of more lights with dimmers rather than fewer lights—you can always dim them.
What's the correct height to hang pendant lights over an island?
Hang pendant lights 30-36 inches above the countertop surface of your island. This provides adequate light for tasks without obstructing the view across the kitchen. For islands with seating, ensure pendants don't hang in people's sightlines when they're seated. If you have 9-foot or higher ceilings, you can go slightly lower for a more dramatic look.
Should I use LED or incandescent bulbs in my kitchen?
Use LED bulbs throughout your kitchen. They use 75% less energy than incandescent, last 15-25 times longer, and produce less heat (important for under-cabinet lighting). Choose LED color temperature carefully: 2700K-3000K (warm white) for dining areas and pendants, 3500K-4100K (neutral white) for general kitchen lighting, or 5000K-6500K (daylight) for task lighting if you prefer crisp, bright light. Modern LEDs are dimmable if you install compatible dimmer switches.
How do I hide the wires for under-cabinet lighting?
The best approach is to run wiring through the wall during renovation and install an outlet inside the cabinet or behind the upper cabinet kick space. Then plug in a low-voltage transformer or hardwire the lights. Alternatively, you can route wires along the back of the cabinet and down inside a corner cabinet to an outlet. For the cleanest look, have your electrician install a junction box inside the cabinet during rough-in so lights can be hardwired.
Ready for the Next Step?
With lighting installed, it's time to add outlet and switch cover plates and test all electrical circuits.
