DMF Lighting Modular Recessed Downlights

Documents

Spec sheets and technical bulletins

The current sheets for the families I quote most, kept here so the links do not die when DMF reorganises its site. Every figure on this page comes off one of these documents or off dmflighting.com; where DMF does not publish something, I say so rather than fill it in. IES files sit on the product pages - tell me the module, package and beam and I will send one over.

The system

Housing, module, trim: three parts you can change independently

Most recessed downlights are one assembly. DMF splits the luminaire into a housing that goes in at rough-in, a module carrying the LED, heat sink and driver together, and a trim that clips to the module - three separate catalogue numbers. DMF calls it "our universal and truly modular solutions" and claims it lets you "make changes on the fly to fixture lumen packages, color temperature, optics, and trims without major repercussions to your budgets or schedules". The brochure puts a number on the coverage: "The DRD Series can support 98% of recessed lighting use cases."

What that buys on a real job is sequencing. Housings go in before drywall; modules and trims arrive later, so the lumen package, colour temperature and beam are still open at a mock-up rather than closed at buyout. If the designer looks at 3000K in a Brickell lobby and wants 2700K, that is a module change from below the ceiling - "as easy as changing a lightbulb", in DMF's words.

Two mechanical points. DMF describes "Patented Twist & Lock Technology" for the trim-to-module connection and "Patented reinforced bar hangers" that "prevent trim sag". And per the brochure, "DMF's driver, heat sink, and the LED chip are all integrated into the module" - no remote driver to find a home for above the ceiling.

The families

What I quote, and where each one lands

DMF publishes a wide index. These four cover most of what I price in Miami-Dade, Broward and Palm Beach. The DRD names people remember are now module codes inside the M Series, not family names: the sheets still print DRD2M for the fixed 4 in. module, DRD4M for the adjustable and DRD5S for the surface module. The 2 in. X Series is now the X Series 3 in., "Formerly Designated as 2 in.", and the DCC cylinder is now the 4 in. Cylinder, "Formerly DCC/M Series".

M Series 4 in. ICDRD2M and DRD4M750 to 1,500 lm, 9.5 to 14.3 W, 93 CRI. The IC-rated residential and hospitality workhorse. Fixed module wet-listed; adjustable damp-listed, covered areas only.

M Series CommercialMD module, non-IC750 to 3,500 lm, 9.5 to 40.5 W. Adds vandal-proof and coastal trims at IK10 and IP66. 0-10V, DALI-2 and Athena only, no TRIAC on this sheet.

X Series 3 in.XMD module500 to 1,500 lm on a 3-1/4 in. cutout, beams from a 10 degree ultra narrow spot, premium metalized trims in brass, copper and graphite.

S Series surfaceDRD5S with F4NC750 lm at 9.5 W and 1,000 lm at 13.0 W, 90-plus CRI, round or square, for ceilings with no plenum at all.

Housings

Shallow plenums, fire-rated ceilings and concrete

The housing catalogue is where DMF earns its place on a renovation. South Florida is full of 1960s and 1970s concrete construction with almost no plenum, post-tension slabs, and ceilings that form part of a rated assembly. DMF publishes a housing for each condition on the same 4-1/4 in. cutout, so the ceiling plan does not change when the condition does.

Cutouts: 4-1/4 in. (108 mm) new construction and standard remodel, 4-1/2 in. (114 mm) fire-rated remodel. The X Series housings use a 3-1/4 in. (82 mm) cutout.

The super shallow is what I reach for on a concrete-deck renovation. Its installation instructions say the "housing comes set at a 3" height, but can be adjusted down to 2.5 should plenum space require it". There is a restriction attached: DMF states "a 2.5" depth is not compatible with DALI controlled fixtures or Adjustable modules." If the job wants DALI-2 or a tilting module, it stays at 3 in. The product page describes the low-profile housing at 2.5 in., but the sheet prints no overall height, so I treat that as a product page figure.

On fire-rated ceilings, DMF's bulletin states the housing with OneFrame technology is "code compliant for a maximum two-hour fire rating when installed in the appropriate fire-rated assembly", citing UL 514A outlet boxes and UL listing QCIT.E469361 and requiring that "the annular space between the ceiling membrane and the box does not exceed 1/8 inch (3.2 mm)" - so no boxed-out cavities or tenting above each can. Read it before arguing with an inspector. The residential sheet also lists ASTM E283 air tight, STC and IIC sound rated, and IC rated.

Dimming and controls

Four protocols, and which module carries which

This is the detail that most often needs correcting on a schedule I am handed. The dimming protocol belongs to the module, not the housing, and the modules do not all offer the same set. The residential M Series module publishes "0-10V (1%), DALI-2 (0.1%), TRIAC/ELV (1%), Lutron Athena Wireless Node (1%)". The Commercial module publishes 0-10V, DALI-2 and Athena only - no TRIAC or ELV on that sheet - and the S Series bottoms out at 5 percent on TRIAC/ELV.

Emergency on the M Series is a 90-minute battery at 5 W output, integrated or remote test switch. DMF publishes DALI-2 compliance and FCC Part 15 Class B on the current sheets.

Built for this climate

Wet, salt and sea turtles

Three things separate a downlight that lasts in South Florida from one that does not. DMF is unusually specific about all three, and about where the limits are, which matters more.

Where I specify it, and how I quote it

The jobs, and the four things I check

High-end residential and multifamily in Miami-Dade, Broward and Palm Beach, where 93 CRI and warm dim to 1800K is what the designer is really asking for. Hotel guest rooms and corridors, where flangeless and dead-front trims disappear and the module swap keeps the mock-up cheap - see hospitality lighting. Concrete-deck renovations with a 3 in. plenum, where the super shallow housing is the only way in. Fire-rated corridors, where the two-hour bulletin saves an argument. Bathrooms, showers and covered lanais, where the wet listing decides it. And beachfront properties under a nesting-season ordinance, where the amber module drops into the same aperture as everything else. Background is on the recessed lighting page.

A DMF order is three catalogue numbers, not one, so four things get checked before a quote goes out. That the housing suits the real ceiling condition and thickness, because IC versus non-IC, fire-rated versus not and 2.5 versus 3 in. are separate part numbers. That the module location listing matches where it is going, since the fixed module is wet-listed and the adjustable damp-listed for covered areas only. That the dimming protocol matches the control system the engineer drew, because TRIAC is not on the commercial module and DALI-2 is not available at 2.5 in. And that the trim is on the order at all, because a housing without a trim is not a fixture.

I represent DMF Lighting through SESCO Lighting, which dmflighting.com lists as the rep for this territory from Coral Springs and Coral Gables. I quote it, I check the submittal against the sheets before it reaches the architect, and I chase the factory when a date slips. DMF is on the SESCO line card.

Questions

Questions I get about DMF Lighting

Can I change the lumen package after rough-in?

Yes, that is the design intent. Housing, module and trim are three part numbers, and DMF states that swapping a fixed module for an adjustable one "is as easy as changing a lightbulb". What you cannot change afterwards is the housing, so the ceiling condition, the IC rating and the fire rating still need to be right on day one.

Which DMF downlights are wet rated?

It depends on the module, not the family. The M Series fixed module is wet listed and IP66; the adjustable is damp listed, covered areas only; the Commercial module is wet listed under covered ceilings only; the 4 in. cylinder pendant is damp listed; X Series and S Series are wet listed.

How shallow can the housing go?

The M Series super shallow housing is set at 3 in. and DMF says it "can be adjusted down to 2.5 should plenum space require it". DMF also states the 2.5 in. depth is not compatible with DALI-controlled fixtures or adjustable modules, so if the job needs either, plan on 3 in.

Is the turtle-friendly version FWC certified?

No, and DMF says so itself: its bulletin states the fixtures "are not currently listed as FWC Certified but are designed within the required specifications", and that as of April 2025 the FWC certification programme is closed to submissions. The sheet does state compliance with the FWC sea turtle lighting guidelines, a Cree amber LED with no colour filter and a wavelength above 560 nm. If your ordinance requires a certified product number, tell me at design stage.

What is the warranty, and where is it made?

Every current DMF spec sheet prints "5 year limited warranty; 50,000 hours" at 70 percent lumen maintenance, validated, DMF says, with an LM-84 full-fixture lifetime protocol. The warranty document on the site is dated August 2014 and gives five years from date of shipment with the usual exclusions. On where it is made: DMF publishes a Carson, California headquarters, an in-house R and D lab and a Southern California warehouse, and says it makes everything it can in-house, but it does not publish a country of manufacture or final assembly, and there is no Made in USA, Buy American or BABA statement anywhere I have read. If a federally funded job needs BABA certification I will ask the factory in writing rather than guess.
