Build and Component Engineering
PC Reflector
The outer polycarbonate reflector ring shapes the initial beam spread and controls glare when the fixture is viewed at an angle.
ALU+PC Reflector
A second aluminum and polycarbonate reflector layer sits closer to the COB source, adding a reflective inner surface that improves beam efficiency and evenness versus a single reflector design.
COB Chip
A single Chip on Board module produces one continuous light point, giving a smooth beam with no visible shadow overlap, which is especially visible on a fully exposed surface mounted fixture.
Metal Housing
The full cylindrical metal body acts as the primary heat sink for both the COB chip and the on board driver, since there is no ceiling void above the fixture to assist with heat dissipation.
DOB Design with COB Light Source
Driver on Board (DOB)
The driver circuit sits on the same board as the COB chip rather than in a separate driver box, keeping the compact cylindrical body simple to manufacture and install.
Fewer Failure Points
Without a remote driver and its connecting harness, there is one less joint in the circuit where a poor connection can cause a field failure over time.
Dual Reflector COB Optics
Pairing a COB chip with two reflector layers, PC outer and ALU+PC inner, produces a wider, more even beam than a single reflector COB design at the same wattage.
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 COB chip and the on board driver. This is why housing material and surface area matter more here than on a recessed fixture of the same wattage.
Why Choose a Surface Mounted COB Downlight
No Ceiling Cutting
Mounts directly to a flat ceiling surface with a base plate, avoiding the need to cut a recessed hole, useful 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.
Focused, Even Beam
The dual reflector COB optics give a more directional beam than a typical SMD surface fixture, useful for accenting artwork, merchandise, or architectural features.
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 UD85R’s metal body is sized to keep the COB chip 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 UD85R Is Typically Installed
- Renovation and retrofit projects: Concrete ceilings or existing finished ceilings where cutting a recessed hole is impractical.
- Retail and showroom accent lighting: 20W or 30W units at 4500K where the dual reflector beam highlights merchandise or displays.
- Hotels and corridors: Where a visible cylindrical fixture with a focused COB beam is part of the design intent.
- Offices with exposed or concrete 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 with directional accent light.
- Galleries and feature walls: High CRI COB output makes color and texture read accurately under the beam.
Frequently Asked Questions
Does the UD85R 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.
How does the dual reflector design differ from a single reflector COB downlight?
The UD85R pairs an outer PC reflector with an inner ALU+PC reflector layer close to the COB chip, spreading light more evenly than a single reflector ring at the same wattage.
What does DOB mean and why does it matter?
DOB stands for driver on board, meaning the driver circuit is integrated onto the same board as the COB chip 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 UD85R be dimmed?
No, the standard UD85R is not dimmable and is designed for on and off wall switch control.
Is this fixture suitable for bathrooms or outdoor areas?
The UD85R 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.
