The Lithonia Lighting WF4-REG-SWW5-90CRI-MW is a 4-Inch switchable LED regressed downlight built for flush-mount, shadow-free ceiling lighting in residential and commercial spaces. Part of the Lithonia Lighting Contractor Select program, this dimmable fixture operates at 120-Volt and 9-Watt, delivering 650-Lumens of output with a field-selectable color temperature of 2700K, 3000K, 3500K, 4000K, or 5000K. The 90 CRI LED engine renders colors accurately, while the White baffle trim and regressed design create a clean, low-glare appearance that blends into most ceiling finishes.

Lithonia Lighting WF4-REG-SWW5-90CRI-MW – Frequently Asked Questions

1) What size ceiling opening does the Lithonia WF4 regressed downlight fit?
The WF4-REG-SWW5-90CRI-MW is a 4-inch aperture downlight, sized for standard 4-inch ceiling cutouts in residential and commercial construction. If your existing cans or cutouts are 6-inch, this is the wrong trade size.
2) How do I set the color temperature on the Lithonia WF4 switchable downlight?
Color temperature is field-selectable on the fixture itself, with five settings: 2700K, 3000K, 3500K, 4000K and 5000K. That means one part number covers all five, so a contractor can set warm 2700K in apartments and 4000K in a corridor off the same box instead of stocking five SKUs.
3) Can I use the Lithonia WF4 downlight to retrofit existing recessed cans?
It is built for both new construction ceiling installations and recessed lighting retrofits in residential and commercial spaces, in a 4-inch aperture. Confirm your existing housings are 4-inch before ordering.
4) I need to standardize downlights across a whole building. Does one part number cover different room types?
That is the point of this one. A single WF4-REG-SWW5-90CRI-MW covers five color temperatures from 2700K through 5000K, set at install, so one stocked item serves corridors, units and offices. It is part of Lithonia's Contractor Select program, built around simplified stocking for electrical contractors and distributors.
5) How bright is the Lithonia WF4 LED downlight and how much power does it draw?
650 lumens at 9 watts on a 120V circuit. For planning a layout, that is a general-purpose output suited to hallways, living spaces and office downlighting rather than high-output task or retail accent duty.
6) Is the Lithonia WF4 downlight dimmable?
Yes, the WF4 regressed downlight is dimmable and works with dimming controls on a standard 120V circuit. Match the dimmer to an LED-rated model for smooth low-end performance.
7) What does the regressed baffle design on this 4-inch downlight actually do?
The light source sits back behind a white baffle trim rather than flush at the ceiling plane, which cuts the direct view of the LED and lowers glare. In bedrooms, hospitality rooms and open offices where people look up or lie under the fixture, that regressed profile is the reason to choose it over a flat flush-lens wafer.
8) Why does 90 CRI matter for a recessed downlight?
The WF4 LED engine is 90 CRI, meaning it renders colors close to natural light. That matters in retail displays, hospitality spaces, kitchens and bathrooms where skin tone, paint and merchandise color need to read true. For back-of-house or utility areas, a lower CRI fixture does the same job.
9) What color is the trim on the Lithonia WF4-REG-SWW5-90CRI-MW?
White baffle trim, which blends into most standard ceiling finishes. It ships as a single configuration under part number WF4-REG-SWW5-90CRI-MW, so there is no finish option to specify when ordering.
