UD103 Anti-Glare SMD Downlight
Plastic-Coated Aluminum Body · DOB Driver · IECEE & CE Certified
The UD103 is built on a plastic-coated aluminum housing with an anti-glare PC diffuser and PC reflector cup, powered by an SMD chip on a DOB (Driver-On-Board) integrated circuit. Factory-tested to IECEE CB and CE standards, it’s offered in 5W–30W options for hospitality, retail, office and residential ceiling lighting — with OEM/ODM support for importers and lighting distributors.
Datasheet at a Glance
Everything a buyer checks first — housing, driver type, certification and optical spec — before requesting samples. Wattage-specific output figures and cut-out sizes are listed further down.
Built for Volume Ordering, Not Just a Showroom Sample
Four things a sourcing manager checks before committing to a container order: housing durability, glare control, driver reliability, and paperwork that clears customs.
Plastic-Coated Aluminum Body
Aluminum core for heat dissipation, coated in plastic for insulation and corrosion resistance. Lighter to ship, more stable in humid or coastal climates than bare metal fixtures.
Anti-Glare PC Diffuser & Reflector
The PC cover and reflector cup work together to control glare angle, giving even, comfortable light distribution — a common spec requirement for office and retail projects.
SMD Chip + DOB Driver
Driver circuitry is built directly onto the light engine (Driver-On-Board), removing the external driver box. Fewer connection points, fewer field failures, slimmer fixture profile.
IECEE CB & CE Certified
Independently tested under the IECEE CB Scheme and certified to CE electrical safety and EMC requirements — documentation available for import compliance and customs clearance.
What’s Inside the Fixture
Three components a technical buyer usually asks about before approving a spec sheet.
PC Cover — Anti-Glare Diffuser
High-transmittance PC lens with a micro-textured surface that spreads light evenly while suppressing direct glare. Also acts as a dust and moisture barrier for the light engine.
SMD Chip / DOB Module
SMD light source integrated with the DOB driver on a single board — higher luminous efficacy, thinner fixture body, fewer solder joints than a separate-driver design.
PC + ALU Housing
Plastic shell over an aluminum thermal base for a balance of heat dissipation and electrical insulation, with spring-clip mounting that fits a range of ceiling thicknesses.
SMD + DOB — What It Means for Your Project
SMD Light Source
SMD chips give a more even light-emitting surface than discrete LEDs, with lower lumen depreciation and more consistent CCT across a production batch — useful when matching fixtures across a large project.
DOB Integrated Driver
Driver-On-Board mounts the driver circuit directly to the light source PCB, eliminating the external driver enclosure. Smaller fixture footprint, simpler wiring on site, and one less component to source and warranty separately.

What You’ll Need for a Sourcing Decision
The details that usually come up between a first sample request and a container order. Exact figures depend on wattage, CCT mix and destination — confirm with our sales team for a formal quotation.
Samples
Pre-production samples available for testing and photometry verification prior to bulk order confirmation.
OEM / ODM
Custom housing color, packaging branding, CCT selection and driver spec available for private-label programs.
Lead Time
Typical production lead time runs from sample confirmation to shipment; exact scheduling depends on order volume and season.
Packaging & Shipping
Export-standard carton packaging with drop-test protection; FOB/EXW/CIF terms available on request.

Questions Buyers Usually Ask
Is UD103 dimmable?
The standard version is non-dimmable. A dimmable driver can be arranged as a custom option — let us know your dimming protocol (TRIAC, 0-10V, DALI) when requesting a quote.
What’s the difference between a DOB driver and a separate external driver?
DOB (Driver-On-Board) mounts the driver directly on the light source PCB, so there’s no separate driver box or long connecting wire. That means a slimmer fixture, fewer parts to fail, and faster installation on site.
What certifications does UD103 carry, and can it be exported?
UD103 has passed IECEE CB Scheme testing and CE certification, meeting electrical safety and EMC requirements for most export markets. Certification documents are available on request to support customs clearance.
Do you support OEM/ODM and small trial orders?
Yes — branding, housing color, CCT and driver configuration can be customized. Contact our sales team with your target quantity and we’ll confirm MOQ, sample lead time and pricing.
What payment terms and trade terms are available?
T/T and L/C are commonly used, with FOB, EXW or CIF shipping terms depending on your destination port. Get in touch for a formal proforma invoice.
