With the rising popularity of LED lighting, LED ceiling fixtures have become widely available. They come in a variety of styles such as panels, downlights, spotlights, and flush mounts. Many are designed to replace traditional incandescent can lights.
How to Choose LED Ceiling Lights
When selecting LED ceiling lights, consider the following factors:
Type of Fixture
LED ceiling lights come in a wide range of fixture types including:
- LED panels – Large flat panels that produce diffuse ambient lighting.
- LED downlights – Recessed canister fixtures that direct light downward.
- LED spotlights – Focused beam of light for accent lighting.
- LED flush mounts – Diffuser panel that mounts directly to the ceiling.
- LED troffers – Panel light designed to replace fluorescent troffers.
Choose the right fixture type based on your lighting needs and ceiling type.
Light Output
Consider the lumen output you need. LED panels typically provide 1800-5000 lumens. Downlights and spotlights range from 400-2500 lumens. Match the light output to the room size.
Color Temperature
LEDs come in different color temperatures, indicated in Kelvin (K). Lower Kelvin ratings like 2700K-3000K produce warm yellow light. 4000K-5000K ranges give bright white light. Choose the right color temperature for your space.
Beam Angle
For spotlights and downlights, the beam angle determines the spread of light. Narrow beams concentrate light while wide beams spread it out.
Dimmability
Ensure any dimmer switches are LED compatible. LEDs require electronic low voltage dimmers.
Smart Lighting
Some LED ceiling lights offer smart integration with voice control, scheduling, automation, etc. Decide if smart features are desired.
Style
Select an LED ceiling light style that fits your interior decor. There are contemporary, modern, rustic, and traditional designs available.
Energy Efficiency
Check the lumens per watt rating. Higher values indicate greater efficiency. Also look for ENERGY STAR rated LED lights.
How to Install LED Recessed Ceiling Lights
Recessed downlight cans are one of the most popular types of LED ceiling fixtures. Here are some step-by-step instructions on installing recessed LED can lights:
Step 1: Turn Off Power
Start by turning off power to the ceiling light circuit at the breaker box. Verify power is off by testing with a non-contact voltage tester.
Step 2: Remove Old Fixture
Take down your existing light fixture. Carefully disconnect wiring. Also note the location and number of ceiling joists for new can placement.
Step 3: Install Housings
Mark the desired locations for the recessed housings on the ceiling. Cut holes in the drywall or plaster using a hole saw. Insert housing canisters and secure with mounting brackets or screws to a joist.
Step 4: Connect Wires
Inside each can housing, connect the incoming circuit wires to the driver and LED module wires using wago connectors or marrettes. Follow the wiring diagram on the driver.
Step 5: Install LED Module
Insert the integrated LED module into the housing can and secure it. The modules are designed for easy plug and play installation.
Step 6: Install Trim
Choose your desired trim finish such as white, nickel, bronze, etc. Push the trim up into the housing until it clicks into place.
Step 7: Test Lights
Restore power and test that all your LED recessed lights are working properly. Enjoy your bright new energy efficient ceiling lighting!
How to Install LED Panel Lights
For large open ceilings, LED panel or troffer lights are a great choice. Follow these guidelines for installing LED panel ceiling fixtures:
Step 1: Turn Off Power
As with any new electrical install, cut power to the circuit and verify it’s off for safety.
Step 2: Mount Back Panels
LED panels typically come with mounting brackets or backer panels. Mount these securely to the ceiling joists spaced as recommended.
Step 3: Connect Wires
Run electrical wiring to each panel light location. Connect the wires from the driver to the incoming circuit wires with wago connectors.
Step 4: Install Panels
Attach the LED light panel to the mounted backer panel. Some use torsion springs, others use clips or screws to secure in place.
Step 5: Finish Wiring
Make any final wiring connections between panels as per manufacturer instructions. Run wiring neatly between locations.
Step 6: Test Lights
With panels installed and wired, restore power and test operation. Verify all connections are secure.
Step 7: Install Diffuser
Many panels use a diffuser lens to soften and spread the LED light. Clip diffusers into place after testing. Enjoy your new professional LED lighting!
Installing New LED Fixtures on Existing Wiring
Many homeowners want to upgrade old fixtures to new LED lights using the existing electrical wiring. Here are some tips:
– Verify the wiring can support an LED load. Older homes may have insufficient wiring.
– LED lights require a neutral wire connection which may be absent in older boxes. Retrofitting may be difficult.
– Use an electronic LED dimmer if dimming is desired. Standard dimmers won’t work properly.
– Match new LED fixture voltage to circuit line voltage, either 120V or 277V.
– For recessed cans, ensure ceiling has adequate depth and access above it.
– Hire an electrician if existing box wiring is very old, damaged, or incorrect voltage. New home wiring upgrades may be required.
– Install fixture per manufacturer instructions. Consult manuals for proper wiring connections.
– Group LED lights on dedicated circuits to avoid overload. Don’t mix LED and incandescent lights on the same dimmer.
– Use wire connectors suitable for solid core wiring like wago connectors or lever nuts.
– Ensure no loose strands when making wire connections. Test lights before completing install.
Safety Tips for DIY Installation
When installing LED ceiling lights yourself, keep these safety guidelines in mind:
– Turn off breaker and verify the power is off before wiring.
– Follow all local electrical codes for permitted work. Permits may be required.
– Use a non-contact voltage tester to double check wires are not live.
– Use fiberglass ladder to access ceiling and avoid falls.
– Wear rubber soled shoes and eye protection when drilling holes.
– Avoid contact with plumbing, ductwork or gas lines hidden in ceiling.
– Connect wires securely so they don’t pull loose. No exposed copper should show.
– Don’t overload circuits by connecting too many lights to the same line.
– Check manufacturer instructions for proper installation procedures.
– Hire an electrician if you lack experience with home wiring projects.
– Consider having an electrician install lights on high ceilings over 10 feet tall.
