WAC Lighting Lotos 4" Round LED Downlight, 5-CCT Switchable, 90 CRI, IC-Rated

The WAC Lighting Lotos 4" Round LED Downlight is a wafer-thin recessed fixture with a remote driver, delivering 1200 delivered lumens at 90 CRI from a steel housing with a frosted TIR lens. It is 5-CCT switchable between 2700K, 3000K, 3500K, 4000K, and 5000K, operates on a 120-277 VAC, 50/60Hz input drawing 12W or 8W depending on configuration, and is IC rated and airtight for shallow-ceiling applications with as little as 3-inch plenum clearance. The fixture installs easily in remodel or new construction projects, with an optional frame-in kit available separately for pre-wired installations.

Key Features

WAC Lighting R4ERDR-W9CS-WT – Frequently Asked Questions

1) Will the Lotos 4 inch round downlight fit a ceiling with only about 3 inches of space above it?
Yes. The Lotos LED recessed kit uses a remote driver instead of a large can housing, so it works in shallow ceilings with as little as 3 inch plenum clearance. That is the main reason to pick it over a conventional 4 inch can: on retrofit work in tight joist bays, over ductwork, or under a concrete deck, there is often nowhere to put a housing at all.
2) Can the WAC Lotos 4 inch downlight go into an insulated ceiling in direct contact with insulation?
It is IC Rated and airtight, so insulation can sit against it and it can be used where an air seal through the ceiling plane is required. That covers most top floor and attic ceilings in multifamily and residential work without needing a separate cover box.
3) Do I have to pick a color temperature when I order the Lotos 4 inch round downlight?
No, and that is the point of the 5CCT version. One fixture switches between 2700K, 3000K, 3500K, 4000K and 5000K, so you stock one part and set the color at install. For a property manager matching new fixtures to existing rooms, that removes the color guess from the order entirely. CRI is 90.
4) What dimmer works with the WAC Lotos 4 inch LED downlight?
The Lotos dims on either ELV or TRIAC control, 100 percent down to 5 percent on both. If you are replacing incandescent cans on an existing forward phase (TRIAC) wall dimmer, the existing control type is workable; on new work an ELV dimmer gives the same 100-5 range. It is not a 0-10V fixture, so do not spec it into a 0-10V control zone.
5) Can I use the Lotos 4 inch downlight on 277 volt commercial power?
Yes. Input is 120-277 VAC, 50/60Hz, so the same part number runs on a 120V residential circuit or a 277V commercial lighting branch. That matters for institutional and MRO buyers standardizing one fixture across a facility with mixed voltages.
6) Is the driver included with the WAC Lotos R4ERDR downlight or do I order it separately?
The driver is included. It is a remote driver that sits in the ceiling cavity beside the fixture rather than in a can, which is what allows the wafer-thin profile. What is not included is the frame-in kit for pre-wiring new construction, which is an optional item sold separately.
7) Is the WAC Lotos R4ERDR-W9CS fire rated?
The R4ERDR-W9CS is the standard version. WAC builds a fire rated Lotos identified by the -FWT suffix, so if your ceiling assembly requires a fire rated fixture, that is the suffix to order rather than this part number.
8) Can the Lotos 4 inch recessed light be installed in an existing finished ceiling, or is it new construction only?
Both. It installs as a remodel fixture cut into finished drywall, or as new construction. For new construction where the electrician wants to rough in before the ceiling closes, WAC offers an optional frame-in kit sold separately for pre-wiring.
9) Should I use the Lotos round downlight or the adjustable gimbal version?
Pick by what the light has to do. The downlight version is fixed and aims straight down, which is what you want for general ambient light on a flat ceiling. The adjustable version has a gimbal that pivots 360 degrees on a hinge, and that is the one for sloped ceilings, wall washing, and accent light on artwork or millwork. On a slope, a fixed downlight throws the beam off the vertical, so the gimbal is the correct choice there.
10) Can I buy the WAC Lotos 4 inch downlight in a case quantity for a whole building?
Three ways to order it in white: single, a pack of 6 (R4ERDR-W9CS-WT-6), and a pack of 24 (R4ERDR-W9CS-WT-24). For a floor or a full unit turn, the 24 pack is the contractor quantity; singles are there for punch list and one-off replacements.
11) Does the Lotos come in other aperture sizes besides 4 inch, and can I get a two or three light version?
Lotos is made in round and square with 2 inch, 4 inch, and 6 inch apertures, so you can hold the same look across a job and change aperture by room. For multi-light bars, WAC uses part R2ESAR-2 for the 2 light configuration and R2ESAR-3 for the 3 light.
12) What finish does the Lotos 4 inch round downlight come in?
White is the finish offered on the R4ERDR-W9CS round downlight, in all three pack quantities. If your spec calls for a black or bronze trim to disappear into a dark ceiling, this part number will not satisfy it.
13) What is the Lotos trim made of and does it glare?
Construction is steel with a frosted TIR lens, and the LEDs are a multiple LED array rather than a single chip, which is what evens out the illumination across the aperture instead of showing hot spots through the lens.
