Commercial-grade
LED down light,
built to run cool.
An 80W COB downlight engineered around one idea: move heat off the chip fast. A die-cast aluminum radiator, PC/ALU reflector and tempered glass work together to hold 90LM/W efficiency over a 15,000-hour service life — for hotel corridors, retail ceilings and open-plan offices.
Φ230 × H120mm
Five reasons this downlight holds up on site
Every spec on the datasheet traces back to a real installation problem — flicker on a dimmer circuit, a driver that cooks itself in a false ceiling, a color shift after year one. UD58 is built against those failure points.
COB single-source chip
One continuous COB light-emitting surface instead of scattered SMD points, for even ud58-beam distribution and fewer visible hotspots through the reflector.
Full aluminum radiator
Finned die-cast aluminum body pulls heat away from the COB chip continuously, keeping the fixture inside its -20°C to +50°C rated range.
90LM/W system efficiency
7200LM from 80W input at AC85-265V, 50/60Hz — about 85% more efficient than an equivalent-output halogen downlight.
≥80Ra color accuracy
Available in 3000K, 4500K or 6500K CCT, all rated ≥80Ra so skin tones, fabrics and signage read true under the fixture.
Concealed installation
Φ200mm cut-out with spring clips for a flush, trim-free ceiling finish — sized for standard 8-inch recessed openings.
15,000H rated life
Driver and chip are matched to run at 0.9/0.9 PF/DF, supporting a 15,000-hour working life under normal indoor conditions.
IP20 indoor rating
Purpose-built for dry indoor ceilings — hallways, lobbies, offices, showrooms — with simple wall-switch on/off control.
Glass + PC/ALU optics
Tempered glass lens over a PC/ALU reflector controls glare while protecting the COB chip from dust ingress.
Five layers, one job: get light out, heat off
Click through the ud58-stack the way our engineers spec it — from the visible face cover down to the radiator that never gets discussed on a spotlight but decides how long the fixture lasts.
ALU Face Cover
Anodized aluminum trim ring that sits flush with the ceiling and frames the light output.
Glass
Tempered glass lens seals the optical chamber, cutting glare and keeping dust off the reflector.
PC/ALU Reflector
Faceted polycarbonate/aluminum reflector shapes the ud58-beam and softens the COB chip’s point source.
COB Chip
Single chip-on-board light source rated 7200LM at 80W — the source of the 90LM/W efficiency figure.
ALU Radiator
Finned die-cast aluminum heatsink draws heat off the chip by convection, protecting lumen output over 15,000 hours.

Every angle, before it ships
A manufacturing partner, not just a line item
We supply lighting distributors, contractors and hospitality fit-out teams who need consistent quality across container-sized orders — not just a single sample that looks good.
OEM / ODM ready
Custom CCT binning, driver protocol, face-cover finish and private-label packaging on the same UD58 platform.
Batch-tested output
Every production run is checked against the 7200LM / 90LM/W / ≥80Ra spec before it leaves the factory, so fixture 1 and fixture 1,000 match.
Engineered for lifespan
The aluminum-radiator-first design isn’t cosmetic — it’s ud58-why we can rate UD58 for 15,000 hours instead of quoting a marketing number.
Export-ready packing
Standardized L620×W500×H260mm cartons sized for efficient container loading and reduced in-transit damage.
Direct factory pricing
No middleman markup — wholesale and project-volume pricing quoted directly against your cut-out count and CCT mix.
Responsive technical support
Talk to the team that ud58-specs the driver, not a call center — for site issues, replacement parts, or a custom CCT run.
Questions procurement teams actually ask
COB (Chip-on-Board) packs many LED dies onto a single substrate to form one continuous light-emitting surface. Compared with multi-SMD arrays, COB gives UD58 a single soft light spot, fewer shadow rings inside the reflector, and easier heat spreading across the aluminum radiator — which is how it holds a stable 90LM/W at 80W.
UD58 has a Φ200mm ceiling cut-out. The fixture body is 8 inch / Φ230mm in outer diameter and 120mm in height, matching standard 200mm recessed downlight openings used in hotel corridors, retail ceilings and office grids.
The standard UD58 is a non-dimmable, wall-switch on/off fixture rated IP20 for indoor concealed installation. If your project needs a dimmable or emergency-driver version, contact us — we support OEM/ODM driver changes on request.
UD58 ships in 3000K warm white, 4500K neutral white, or 6500K cool white, all rated ≥80Ra, so the same fixture body works for warm hospitality lighting or cooler task lighting in offices and retail.
UD58 is rated for 15,000 hours of working life and operates from -20°C to +50°C, with roughly 85% energy saving compared to an equivalent-output halogen downlight.
Yes. UD58 supports OEM/ODM programs including custom CCT binning, driver/dimming protocol, face-cover finish and private-label packaging. Standard packing size is L620×W500×H260mm — contact us for MOQ and lead time.
