WAC Lighting Lotos 4in 5-CCT Selectable LED Recessed Downlight, 9W 725 Lumens, Wet Location
The WAC Lighting Lotos is a versatile 4in LED recessed downlight built for shallow-ceiling installations, packing a high-output 9W integrated LED module rated at 725 lumens and 90 CRI into a die-cast aluminum housing with a 20-gauge steel driver box. Selectable 5-CCT color temperature (2700K, 3000K, 3500K, 4000K, 5000K) lets installers dial in the right light on site, while ETL & cETL listing under UL 1598 covers Dry, Damp, and Wet Location use. With as little as 2in of plenum clearance required and a 4.25in cutout, Lotos fits remodel or new-construction ceilings where a full housing won't.

WAC Lighting R4ERDR-W9CS-FWT-24 – Frequently Asked Questions
1) Will the WAC Lotos 4in recessed downlight fit a ceiling with less than 2 inches of plenum space?
Yes. The Lotos 4in is built for shallow plenums and needs as little as 2in of clearance above the ceiling. The light engine connects to a separate driver box with a male-to-female quick-connect locking cable, so the driver box can be tucked into the joist bay rather than sitting directly behind the aperture. Cutout is 4.25in, and it works in ceiling thicknesses from 0.5in to 1.5in.
2) Can I use the Lotos 4in LED downlight in a shower or on a covered exterior porch?
Wet location rated, so yes to both. The Lotos 4in is ETL and cETL Listed to UL 1598 for Dry, Damp, and Wet Locations, which covers shower trims, soffits, and covered outdoor ceilings. It is also airtight and IC-rated, so it can sit in direct contact with insulation.
3) Do I have to order a separate color temperature for each room, or is the Lotos selectable on site?
One part number covers five color temperatures. A switch on the Lotos selects 2700K, 3000K, 3500K, 4000K, or 5000K, so an electrician can set warm light in a lobby and cooler light in a back-of-house corridor from the same box of fixtures. That cuts the number of SKUs a property manager or MRO stockroom has to carry.
4) Will the Lotos 4in run on 277V commercial power?
Yes. The driver is universal input and operates on 120V, 240V, and 277V, so the same fixture goes into a residential 120V circuit or a 277V commercial lighting branch without a separate transformer or a different part number.
5) Does the Lotos 4in meet California Title 24 for new residential construction?
Yes. The Lotos 4in is CEC Title 24 Compliant and Title 24 JA8-2016 Certified, and it carries Energy Star 2.0 certification. That combination is what inspectors look for on high-efficacy luminaire requirements in California work.
6) Do I need to buy a housing or frame-in kit with the Lotos 4in downlight?
No housing is required. Retention clips hold the light engine in the 4.25in cutout, and the driver box has 5 knockouts for the branch circuit connections. On exposed ceilings where you want to pre-wire before the drywall goes up, WAC offers the RER-FRAME frame-in kit, sold separately. The LED module is integral and included, so there is no lamp to buy.
7) What dimmers work with the WAC Lotos 4in LED recessed light?
The Lotos 4in dims on ELV and TRIAC dimmers. On ELV it runs smoothly down to 10 percent; on TRIAC it goes down to 5 percent. If you are specifying for a hospitality or multi-family job where the dimmers are already standardized, the TRIAC path is the one that gets you the deeper low end.
8) Is 725 lumens from a 4 inch downlight enough for a kitchen or corridor?
The Lotos 4in puts out 725 lumens from a 9W module with a flood beam spread and 90 CRI. Flood distribution plus 90 CRI suits general ambient coverage in kitchens, baths, and living spaces, and it is the color rendering level usually specified for hospitality and retail where finishes and skin tones have to read correctly. Rated lamp life is 50,000 hours.
9) What is the Lotos 4in housing actually made of, and will it hold up in a rental turnover?
The light engine sits in a die-cast aluminum housing, with a 20-gauge steel driver box, and the lens is a frosted acrylic diffuser. The frosted acrylic spreads the light evenly and there is no glass to break during a turnover or a ceiling repair.
10) Is the Lotos 4in hardwired or does it plug in?
Hardwired, ceiling mounted. Connections are made in the 20-gauge steel driver box, which has 5 knockouts, and a quick-connect locking cable runs from there to the light engine. Plan on a licensed electrical connection at each location, not a plug.
