Square Surface Mounted LED Panel Light
Built for Ceilings You Can’t Cut — UP47S
Most square panel lights are made to recess into a hole — which is no help on a concrete slab, a fire-rated ceiling, or a retrofit job where cutting isn’t an option. UP47S is a square surface mounted LED panel light that screws straight onto the ceiling face instead, carrying over the same PS light guide plate and DOB integrated driver as our round UP47R, just in a square profile for projects specified to a square ceiling grid. Offered in 6W–24W, with OEM/ODM support for importers, distributors and lighting contractors sourcing a square no-cut ceiling light supplier.
Datasheet at a Glance
Everything a buyer checks first — shape, mounting type, driver and optics — before requesting samples. Wattage-specific output figures and overall sizes are listed further down.
A Square No-Cut Ceiling Light With Even, Diffused Output
A square surface mounted LED panel light for concrete ceilings and retrofit renovation covers two requirements at once: matching a square ceiling grid or fixture layout, and installing without cutting into a slab you can’t — or shouldn’t — drill through.
Square Profile
A squared trim matches square ceiling grids, air vents, sensors and switch plates — useful on projects specified to a consistent square fixture layout throughout.
PS Light Guide Plate
Light from the SMD chip is spread edge-to-edge across a polystyrene guide plate, giving a soft, evenly diffused glow across the whole face rather than a visible point source.
DOB Integrated Driver
Driver circuitry is built onto the light source board, removing the external driver box. Fewer connection points, faster installation, and a slimmer overall profile.
No Cutting Required
Screw-mount installation onto the ceiling surface — no hole cutting, no recess depth to plan for, and no risk of hitting rebar or conduit inside a concrete slab.
What’s Inside the Fixture
Three components a technical buyer usually asks about before approving a spec sheet.
PS Light Guide Plate
A polystyrene guide plate distributes light from the SMD source across the entire square face of the fixture, producing an even glow rather than a visible hot spot.
SMD Chip
The SMD light source sits behind the guide plate with the DOB driver on the same board, feeding light evenly into the diffusion layer.
Plastic Housing
A lightweight plastic body holds the light engine, with a stepped square base plate that screws flush to the ceiling — no recess or cutting required.
Guide Plate + DOB — What It Means for Your Project
Why a Light Guide Plate
Rather than exposing the SMD chip directly, UP47S channels light through a PS guide plate first — the same principle used in slim panel lighting to eliminate visible hot spots and give a flatter, more uniform light output across the face of the fixture.
DOB Integrated Driver
Driver-On-Board mounts the driver circuit directly to the light source PCB, so there’s no separate driver enclosure to wire in. On a surface-mounted fixture this keeps the base plate slim and installation quick — just wire and screw to the ceiling.
Wattage & Output Comparison
UP47S is available in 6W, 9W, 12W, 18W and 24W. As a surface-mounted fixture there is no cut-out size to plan for — select by required overall footprint and target illuminance.

Where UP47S Is Typically Specified
As a screw-mount, no-cut square ceiling light, it’s best suited to concrete or solid slabs, retrofit renovation projects, and layouts where a square fixture needs to align with an existing square grid.

Questions Buyers Usually Ask
Is there a square LED panel light that doesn’t need a ceiling cut-out?
Yes — UP47S is a square surface mounted panel light designed exactly for that. It screws directly onto the ceiling surface using its base plate, rather than recessing into a hole, which is the standard approach for concrete slabs, fire-rated ceilings and retrofit jobs where cutting isn’t practical.
What’s the difference between UP47S and the round UP47R?
Same light engine and driver — PS guide plate, SMD chip, DOB driver — just a square trim instead of round. UP47S suits projects specified to a square ceiling grid or where fixtures need to align visually with square vents, sensors or switch plates.
How is UP47S installed?
UP47S mounts with a stepped square base plate that screws directly to the ceiling surface — no hole cutting, no recess depth to plan for.
Is UP47S 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.
Do you support OEM/ODM and small trial orders?
Yes — branding, housing color and CCT can be discussed for private-label programs. 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.
