Model UD64 · COB LED Downlight
UD64 60W COB LED Downlight — 8 Inch Recessed Ceiling Light, 5400LM
A 60W COB recessed downlight built on the same aluminum-radiator platform as our UD-series: Φ200mm cut-out, ≥80Ra color rendering, and 90LM/W efficiency for hotel corridors, retail ceilings and office grids that run lights 10+ hours a day.

Product Features
Why this 60W downlight holds up on site
UD64 shares its aluminum radiator, PC/ALU reflector and glass lens with our higher-wattage models — scaled down to 60W / 5400LM for spaces that don’t need 80W but still need a fixture that won’t fade or overheat.
01
COB single-source chip
One continuous COB light-emitting surface for even beam distribution and minimal visible hotspots through the reflector.
02
Full aluminum radiator
Finned die-cast aluminum body pulls heat off the COB chip continuously, keeping the fixture inside its -20°C to +50°C rated range.
03
90LM/W efficiency
5400LM from a 60W input at AC85-265V, 50/60Hz — around 85% more efficient than an equivalent-output halogen downlight.
04
≥80Ra color accuracy
Available in 3000K, 4500K or 6500K CCT, all rated ≥80Ra so fabrics, signage and skin tones read true under the fixture.
05
Φ200mm concealed install
Spring-clip mounting into a Φ200mm cut-out for a flush, trim-free ceiling finish — matches standard 8-inch recessed openings.
06
15,000H rated life
Driver and chip run at 0.9/0.9 PF/DF, supporting a 15,000-hour working life under normal indoor conditions.
07
IP20 indoor rating
Built for dry indoor ceilings — hallways, lobbies, offices, showrooms — with simple wall-switch on/off control.
08
Glass + PC/ALU optics
Tempered glass lens over a PC/ALU reflector controls glare while sealing the COB chip against dust ingress.
Cross-Section
Five layers, one job: get light out, heat off
Click through the stack the way our engineers spec it — from the visible face cover down to the radiator that decides how long the fixture actually lasts.
01
ALU Face Cover
Anodized aluminum trim ring that sits flush with the ceiling and frames the light output.
02
Glass
Tempered glass lens seals the optical chamber, cutting glare and keeping dust off the reflector.
03
PC/ALU Reflector
Faceted polycarbonate/aluminum reflector shapes the beam and softens the COB chip’s point source.
04
COB Chip
Single chip-on-board light source rated 5400LM at 60W — the source of the 90LM/W efficiency figure.
05
ALU Radiator
Finned die-cast aluminum heatsink draws heat off the chip by convection, protecting lumen output over 15,000 hours.

Why Choose Us
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 UD64 platform.
Batch-tested output
Every production run is checked against the 5400LM / 90LM/W / ≥80Ra spec before it leaves the factory.
Engineered for lifespan
The aluminum-radiator-first design is why we can rate UD64 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 specs the driver, not a call center — for site issues, replacement parts, or a custom CCT run.
FAQ
Questions procurement teams actually ask
UD64 uses the same COB chip, aluminum radiator and Φ200mm cut-out body, but is binned to 60W / 5400LM instead of 80W / 7200LM. It suits spaces that want the same 90LM/W efficiency and ≥80Ra color rendering at a lower wattage and lower per-fixture running cost.
UD64 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 UD64 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.
UD64 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.
UD64 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. UD64 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.
