RGB RGBW DMX512 LED Downlights Addressable and Programable

DMX512 control brings real flexibility to recessed LED downlights, and the FEL-AD2 series delivers it without extra complexity. These are straightforward fixtures: RGB or RGBW COB LEDs inside a round aluminum housing, wired for DMX daisy-chaining, ready to install in standard ceiling cutouts.

Tech specs at a glance

Three sizes cover the practical range. The FEL-AD2 8W runs 400 lumens from a 64mm housing (55mm cutout). The 12W version pushes 600 lumens from an 85mm housing (75mm cutout). The 20W variant delivers 1200 lumens from a 105mm housing (95mm cutout). All three draw 24V DC.

Beam angle matters for different applications, so each fixture works with 15°, 24°, or 38° lenses. The 15° option punches a narrow column of light — good for accenting artwork or architectural details. The 24° lens is the middle ground, suitable for general task lighting. The 38° spread covers broader areas with softer edges.

Color temperature sits at 3000K for the white channel in RGBW units. The RGB-only version relies on color mixing to produce white tones.

Build and installation

The housing is round, machined from aluminum, with a white trim ring that sits flush against the ceiling. Aluminum does double duty as structural body and heat sink. LED junction temperatures stay under control without active cooling — no fans, no noise.

Installation follows standard recessed procedure. Cut the hole to spec (55mm, 75mm, or 95mm depending on model), connect the 5-wire cable, and push the unit into place. The mounting clips hold it firm.

Each fixture has a 20cm input cable and a 20cm output cable, both with five wires. The five-wire layout follows standard DMX512 pinout: DMX+, DMX-, common, plus power and ground for the 24V feed. This makes daisy-chaining from one fixture to the next straightforward — run the DMX line and power bus through the chain, terminate the last fixture.

Control system integration

The FEL-AD2 responds to standard DMX512 protocol. Any DMX controller that outputs 512-channel frames will drive these fixtures — that covers most lighting desks, PC-based control software, and standalone DMX programmers.

Each fixture occupies one DMX address space. With RGB fixtures that is three channels (red, green, blue). RGBW adds a fourth channel for white. Addressing is set via DIP switches on the back of the housing. Set the starting address before installation if possible — it is easier at a bench than on a ladder. The DMX implementation supports 8-bit resolution (256 steps per channel), giving smooth fades between levels. No custom protocols or proprietary software needed.

What is in the box

Each unit ships as a single fixture with the 20cm input and output cables attached. The lens is pre-installed unless a different angle was specified at order. Mounting clips are included. The IP42 rating means the fixture is splash-proof — fine for bathrooms, covered outdoor areas, and commercial kitchens.

What you need to supply

The FEL-AD2 is a fixture-only product. You provide:

• A 24V DC power supply rated for the total wattage of all connected fixtures, plus 20% headroom
• A DMX512 controller — lighting desk, PC interface, or standalone controller
• DMX termination resistor (120 ohm) for the last fixture in the chain
• Standard wiring tools and ceiling cutout saw

Where it gets used

Retail spaces use color to draw attention — warm white over general merchandise, color sweeps over featured displays, programmed to shift through the day. Bars and restaurants shift atmosphere between service times with recalled DMX scenes. Theaters and stages integrate these with existing DMX rigs where traditional PAR cans do not fit the ceiling grid. Architectural lighting projects use them for facade illumination where the 15° and 24° lenses put light exactly where needed. Event spaces reconfigure between bookings — wedding, corporate presentation, product launch — each with its own lighting scene stored and recalled on demand.

Lifespan and reliability

Rated at 50,000 hours. At 12 hours of daily use, that is over 11 years. The aluminum housing and passive cooling mean no moving parts or fans to fail. If a fixture does go down, the daisy-chain wiring means the rest of the chain keeps running — swap the failed unit and re-terminate the DMX line.

Why do buyers pick these over the alternatives? Here is what we hear from customers:

DMX integration. These fixtures speak standard DMX512 — no gateways, no protocol conversion, no proprietary dongles. If you already run DMX for other lighting, the FEL-AD2 drops into that network. For new installations, any off-the-shelf DMX controller works.

Build quality. The aluminum housing is thicker than most downlights in this price range. Passive cooling means no fans to fail or filters to clean. Installers tell us the 5-wire daisy-chain cabling saves time on multi-fixture runs.

Power flexibility. Running 8W, 12W, and 20W units on the same 24V bus — with the same DMX control — makes layout design easier. You pick the lumen output per zone without adding control complexity.

Long service life. The 50,000-hour rating means most buyers fit and forget. The modular cabling makes swapping a single fixture straightforward without disturbing the rest of the chain.

DMX512 RGB and RGBW LED downlights fit a range of settings where controllable color lighting adds value.

Entertainment venues — theaters, clubs, and concert halls. DMX control is already standard in those spaces, so the FEL-AD2 integrates with existing rigs. The small form factor fits ceiling grids where PAR cans or wash fixtures do not.

Architectural lighting — facade illumination and feature wall washing. The 15° and 24° lenses put light exactly where needed without spill. Multiple fixtures on a single DMX run means whole building fronts can shift color as one program.

Retail displays — color draws attention. Warm white over general stock, a color sweep over featured merchandise, programmed to shift through the day. The 38° lens covers wider shelves, the 15° lens spotlights mannequins or signage.

Hospitality — hotels, restaurants, bars. Ambiance changes between service periods. Breakfast lighting differs from dinner service. DMX scenes are recalled from a touch panel or schedule with no manual per-fixture dimming.

Event spaces — weddings, corporate presentations, product launches. Each event has different lighting requirements. DMX scenes are stored and recalled per booking. The daisy-chain wiring means fixtures stay in place while the control configuration changes.

A few things to check before ordering:

DMX compatibility. Confirm your controller outputs standard DMX512. Some building management systems use DALI or 0-10V dimming, which are not directly compatible.

Power supply placement. 24V DC loses voltage over long cable runs. Keep the power supply within 15-20 meters of the farthest fixture, or calculate voltage drop for your wire gauge.

Cutout sizes. Measure your ceiling holes before ordering. The three sizes cover 55mm, 75mm, and 95mm cutouts.

Lens selection. Specify the beam angle when ordering. Swapping lenses in the field is possible but takes time.

Spare units. For multi-zone installations, keep at least one spare per size. If a fixture fails, having a matching spare avoids project delays.

Weather exposure. IP42 is splash-proof, not weather-proof. Do not install in locations exposed to direct rain or pressurized washdowns.

Cable runs. The built-in cables are 20cm each. For longer runs between fixtures you will need junction boxes or extension cables. Plan your wiring topology before mounting.

Warranty. Check the terms before installation. Some conditions require professional installation by a licensed electrician.
