WF4 LED Recessed Downlight
Our WF4 LED recessed downlight brings professional-grade lighting to any residential or commercial space. Engineered with a wafer-thin profile that installs directly into drywall without recessed housing, the WF4 simplifies retrofit and new construction projects alike.
This flush-mount LED fixture delivers 650 lumens of bright, uniform illumination while consuming just 9 watts of power. The integrated LED module offers 50,000 hours of maintenance-free operation, and the selectable color temperature switch lets you choose between 3000K soft white, 4000K neutral white, or 5000K daylight at installation.
- Ultra-slim wafer design — less than 0.5 inches thick for direct drywall installation
- 650 lumens output at 9 watts for energy-efficient performance
- Selectable CCT switch: 3000K, 4000K, or 5000K color temperatures
- Integrated LED rated for 50,000 hours of operation
- Dimmable down to 5% with compatible TRIAC and ELV dimmers
Installation & Housing Compatibility
The Lithonia Lighting WF4 eliminates the need for traditional recessed cans, making it ideal for retrofit applications where ceiling access is limited. The wafer-thin housing mounts directly to drywall using integrated spring clips that grip from above, while the junction box adapter connects to standard electrical boxes.
For new construction, the WF4 installs just as easily once drywall is in place. The IC rating allows direct contact with ceiling insulation without creating fire hazards or reducing fixture lifespan. Installers appreciate the tool-free mounting system that requires only a 4.25-inch ceiling cutout.
Light Output & Color Temperature Selection
Each WF4 delivers 650 lumens of bright, evenly distributed illumination across its 4-inch aperture. The frosted polycarbonate lens diffuses light smoothly, eliminating harsh shadows and hotspots common with exposed LED chips.
Before installation, use the small selector switch on the driver to choose your preferred color temperature. The 3000K setting produces warm white light similar to traditional incandescent bulbs, ideal for living rooms and bedrooms. The 4000K neutral white suits kitchens, offices, and task-oriented spaces where clarity matters. The 5000K daylight setting replicates natural outdoor light, popular in garages, workshops, and commercial environments.
Wet Location Rating & Application Versatility
The WF4 carries a wet location rating, allowing installation in bathrooms, laundry rooms, covered porches, and other areas exposed to moisture. The sealed lens and gasketed housing prevent water intrusion, while the corrosion-resistant aluminum construction withstands humid conditions without degrading.
Homeowners often use the WF4 in shower ceilings, directly above bathtubs, or in outdoor soffits where traditional recessed cans would require expensive wet-rated housings. The compact profile also makes it popular for closets, hallways, and small spaces where deeper fixtures would intrude into limited ceiling cavities.

What people are saying
WF4 Downlight Questions
Yes, the WF4 carries an IC (Insulation Contact) rating, meaning it can be installed in direct contact with ceiling insulation without fire risk or performance degradation. The fixture's thermal management system dissipates heat efficiently even when surrounded by insulation, maintaining the LED's 50,000-hour lifespan.
This IC rating makes the lithonia lighting wf4 ideal for modern energy-efficient homes with fully insulated attics and ceiling cavities.
The WF4 requires a 4.25-inch diameter hole in the ceiling drywall. This slightly oversized cutout compared to the 4-inch aperture allows the spring mounting clips to grip properly from above.
Use a standard 4.25-inch hole saw for clean cuts. The white trim ring covers the cutout completely, hiding any minor imperfections around the edge.
The CCT selector switch is accessible only before installation, so choose your preferred color temperature—3000K, 4000K, or 5000K—before mounting the fixture. Once installed, changing the setting would require removing the downlight from the ceiling.
For homes with varied lighting needs, consider installing different color temperatures in different rooms: 3000K for bedrooms and living areas, 4000K for kitchens and bathrooms, 5000K for workspaces.
The WF4 is compatible with most smart dimmer systems that support LED loads, including Lutron Caseta, Leviton Decora Smart, and similar TRIAC or ELV-based dimmers. Check your dimmer's specifications to ensure it's rated for LED fixtures and supports the WF4's 9-watt load.
For best performance, install multiple WF4 fixtures on the same circuit to meet minimum load requirements that some smart dimmers need for reliable operation.
The WF4 uses integrated spring clips that compress during installation and then expand to grip the back of the drywall. Simply push the fixture up into the ceiling cutout until the clips snap into place—no tools required.
The electrical connection happens via a standard junction box (sold separately or using an existing box). The included junction box adapter and wire nuts make wiring straightforward for both DIY installers and licensed electricians.
The 3000K setting produces a soft, warm white light similar to traditional incandescent bulbs—ideal for living rooms, bedrooms, and dining areas where you want a cozy atmosphere. The 4000K neutral white resembles natural daylight through a window, perfect for kitchens, bathrooms, and offices where tasks require clear visibility.
The 5000K setting delivers bright, cool daylight that enhances alertness and color accuracy, making it popular in garages, workshops, laundry rooms, and commercial spaces.
Yes, the wet location rating qualifies the WF4 for direct installation in shower ceilings, tub surrounds, and other areas where it may be exposed to water spray or high humidity. The sealed lens and gasketed housing prevent moisture intrusion that would damage non-rated fixtures.
Ensure all electrical connections use appropriate wet-location-rated junction boxes and follow local building codes for bathroom lighting installations.
