Wattage Lineup
Build and Component Engineering
PC Reflector
A black polycarbonate reflector ring surrounds the light source to cut glare and control the visible cutoff angle, a detail buyers in hospitality projects often ask for specifically.
PS Light Guide Plate
Spreads light from the SMD chip evenly across the lens surface, avoiding the visible dot pattern that lower cost SMD downlights sometimes show.
SMD Chip
Surface mounted diode array positioned behind the light guide plate, delivering 80 to 90 LM/W efficiency across the range.
Metal Housing
Full metal body rather than a metal and plastic hybrid, giving a heavier feel and steady heat dissipation to support the 15,000 hour rated life.
DOB Design with SMD2835 Chips
Driver on Board (DOB)
The driver circuit is built directly onto the same PCB as the LED chips instead of housing a separate driver box. This removes one component from the assembly, shortens the electrical path between driver and chip, and reduces the overall fixture depth, which helps in shallow ceiling voids.
Fewer Failure Points
With no separate driver enclosure or connecting wire harness between driver and light engine, there is one less connection point where a poor solder joint or loose wire can cause a field failure.
SMD2835 LED Chips
SMD2835 is a widely used surface mount LED package sized 2.8mm by 3.5mm, chosen for a stable balance of lumen output, cost, and thermal behavior at this wattage range.
Consistent Chip Binning
Using a single established chip format across all four wattages keeps color consistency tighter between units from the same production batch, which matters when many fixtures are installed in one visible ceiling area.
DOB fixtures run the driver components at the same location as the LED heat source, so the metal housing and PS light guide plate spacing on the UD84 are sized to keep both the chips and the on board driver components within safe operating temperature through the minus 20C to plus 50C rated range.
Why the UD84 Performs Well in the Field
Glare Controlled Design
The black reflector ring reduces visible brightness when viewed at an angle, useful in meeting rooms and hotel corridors where fixtures sit within eye line.
Even Light Guide Diffusion
The PS light guide plate removes the pixelated look some SMD downlights have, producing a smoother lit surface.
Higher Efficiency Range
80 to 90 LM/W across the lineup, edging out typical COB alternatives at the same wattage tier.
Metal Body Construction
Full metal housing adds thermal mass and a more premium hand feel compared to metal and plastic hybrid competitors.
Wide Ambient Range
Rated from minus 20C to plus 50C, suitable for ceiling voids that see significant heat buildup.
Three Color Temperatures
3000K, 4500K, and 6500K covers warm hospitality lighting through to daylight retail and office lighting from one product line.
Voltage Compatibility, Please Note
Built for High Ambient Temperature Regions
Thermal Performance in Hot Climates
Ceiling voids without direct air conditioning, rooftop storage, and staging in unshaded warehouse areas can all push ambient temperature well past typical room conditions before a fixture is even installed. The UD84’s metal housing is sized to keep the SMD chip within safe operating temperature through this range rather than only under lab conditions.
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.

- Offices: 10W or 20W at 4500K across a standard ceiling grid.
- Restaurants and cafes: 3000K for a warm, low glare dining atmosphere.
- Residential interiors: 7W for hallways and closets, 10W for bedrooms, 20W for living rooms and kitchens.
Frequently Asked Questions
How is SMD with a light guide plate different from a standard SMD downlight?
A standard SMD downlight often shows individual chip points through the lens. Adding a PS light guide plate spreads the light across a wider internal surface before it exits, producing a more even, less dotted appearance.
Why is the input voltage range narrower than some other downlights?
The UD84 driver is rated AC 170 to 265V. This covers standard 220V and 230V mains with normal fluctuation, but does not cover very low voltage conditions below 170V that a wider range 85 to 265V driver would tolerate.
Can the UD84 be dimmed?
No, the standard UD84 is not dimmable and is designed for on and off wall switch control.
What ceiling cutout size does each wattage need?
7W needs Ø70mm, 10W needs Ø100mm, 20W needs Ø140mm, and 30W needs Ø200mm.
Is this fixture suitable for bathrooms or outdoor areas?
The UD84 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.
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 LED chips rather than housed in a separate box. This gives a slimmer fixture profile and fewer wired connections compared to a fixture with a remote driver.
Why SMD2835 specifically instead of another chip size?
SMD2835 is a common surface mount package that offers a stable balance of brightness, cost, and thermal behavior for downlights in the 7W to 30W range, and is widely available across LED chip suppliers, which supports consistent long term sourcing.
