UD84R Surface Mounted LED SMD Downlight | DOB Driver on Board Ceiling Light, 7W to 30W, CB/IECEE/CE Certified
A surface mounted SMD downlight with a DOB driver on board circuit and a PS light guide plate for even, shadow free light. No ceiling cutting is required, making it a fast retrofit option for concrete ceilings, renovation projects, and buildings where drilling a recessed hole is not practical. Available in four wattages and two housing colors.

Wattage Lineup
Build and Component Engineering
PC Reflector
A black polycarbonate reflector ring controls glare and defines the visible light cutoff, keeping the source from being directly visible at an angle.
PS Light Guide Plate
Spreads light from the SMD chip evenly across the lens surface, avoiding a visible dot pattern from the individual LED points.
SMD Chip
Surface mounted diode array delivering 80 to 90 LM/W efficiency across the wattage range.
Metal Housing
The full cylindrical metal body doubles as the heat sink, since there is no ceiling void above the fixture to help dissipate heat as with a recessed design.
DOB Design with SMD Light Source
Driver on Board (DOB)
The driver circuit is built directly onto the same PCB as the LED chips instead of a separate driver box, which keeps the compact cylindrical body simple to manufacture and install.
Fewer Failure Points
No remote driver enclosure or connecting harness between driver and light engine, removing a common source of field failures.
Compact Body
DOB construction keeps the surface mounted housing shallow relative to its light output, which matters visually for a fixture that stays fully exposed below the ceiling.
Simple Wiring
A single cable exits the base plate directly to the junction box, with no additional driver to mount separately above the ceiling.
Because a surface mounted body has no ceiling void to help pull heat away, the metal housing carries the full thermal load for both the SMD chips and the on board driver. This is why body material and surface area matter more here than on a recessed fixture of the same wattage.
Why Choose a Surface Mounted Downlight
No Ceiling Cutting
Mounts directly to a flat ceiling surface with a base plate, avoiding the need to cut a recessed hole, which matters on concrete slabs or ceilings where cutting is not practical.
Fast Retrofit
Suitable for renovation projects where a recessed downlight would require re-routing above an existing finished ceiling.
Visible Design Element
The cylindrical body sits below the ceiling plane and is available in white or black, so it can be selected to match or contrast with the ceiling finish as a visible design element.
Even SMD Beam
The light guide plate keeps the beam smooth rather than showing individual chip points, which is more noticeable on a surface mounted fixture viewed up close.
Voltage Compatibility, Please Note
Built for High Ambient Temperature Regions
Thermal Performance in Hot Climates
A surface mounted body carries its full heat load without help from a ceiling void, which makes housing material and design more important in hot ambient conditions than on a recessed fixture. The UD84R’s metal body is sized to keep the SMD chips and on board driver within safe operating temperature through the rated range.
Certifications and Market Access
Current Certifications
CB Certificate and IECEE: Testing follows IEC 60598 under the CB Scheme, and because the scheme works on mutual recognition, the test report can be presented to national certification bodies in over 50 member countries instead of repeating full safety testing in each destination market.
CE Marking: Confirms compliance with the EU Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU, required for legal sale across the EU, Norway, Iceland, Liechtenstein, and Switzerland.

Where the UD84R Is Typically Installed
- Renovation and retrofit projects: Concrete ceilings or existing finished ceilings where cutting a recessed hole is impractical.
- Hotels and corridors: Where a visible cylindrical fixture is part of the design intent rather than a flush recessed look.
- Retail stores: 20W or 30W units at 4500K for accent and general lighting on exposed ceiling structures.
- Offices with concrete or exposed ceilings: 10W or 20W at 4500K where no ceiling void exists for a recessed fixture.
- Restaurants and cafes: 3000K in a black housing for a warm, low profile industrial look.
- Residential interiors: 7W or 10W for hallways, entryways, and feature lighting where a recessed cutout is not an option.
Frequently Asked Questions
Does the UD84R require a ceiling cutout?
No. This is a surface mounted fixture that attaches to a flat ceiling via a base plate, with no cutting or hole required.
What does DOB mean and why does it matter?
DOB stands for driver on board, meaning the driver circuit is integrated onto the same PCB as the SMD chips rather than housed in a separate box, keeping the surface mounted body compact.
What housing colors are available?
Standard options are white and black. Additional finishes can be discussed for qualifying bulk orders.
Can the UD84R be dimmed?
No, the standard UD84R is not dimmable and is designed for on and off wall switch control.
Is this fixture suitable for bathrooms or outdoor areas?
The UD84R carries an IP20 rating and is intended for dry indoor locations only.
Is SASO/SABER certification included?
SASO/SABER registration is handled separately from CB, IECEE, and CE. Please confirm current SASO/SABER status for this model with the supplier before placing an order intended for the Saudi market.
Why is the input voltage range 170 to 265V rather than a wider range?
This range covers standard 220V and 230V mains with normal fluctuation. Sites with voltage that can drop below 170V should confirm compatibility or ask about a wider range driver option.
