Sunco Lighting Sunco 12 Pack 2x4 LED Flat Panel Light Drop Ceiling Office Fixture, 7700 LM, Selectable Features, 40W/50W/60W, 4000K/5000K/6000K, Dimmable (0-10V), Dustproof ETL.

Why I chose the Sunco 2x4 LED panel

I’ve slowly been replacing aging fluorescent troffers across a couple of spaces—an office with a grid ceiling and a utility area with a mix of exposed joists and suspended sections. I wanted uniform, high-output light with modern controls, predictable glare, and simple install logistics. The Sunco 2x4 LED panel checked the right boxes on paper: selectable wattage (40/50/60W), three CCT options (4000K/5000K/6000K), 0–10V dimming, ETL listing, and a dustproof, backlit design in a slim package. A 12-pack made sense for coverage and consistency.

After several weeks of use and a range of install scenarios, here’s how it performed.

Build and design

This is a backlit panel, not an edge-lit light guide, and that shows up in uniformity and rigidity. The face diffuser is evenly lit end-to-end with no diode “hot spots,” and the overall profile stays quite slim. The housing is lightweight aluminum and the lens is a frosted acrylic. The unit feels purpose-built for drop ceilings—wide, flat, and easy to handle—but like most large-format panels, the lens can be vulnerable to flexing or impacts. Handle these by the frame, not by the face, and keep them on a flat surface until they’re seated in the grid.

The switches for wattage and CCT are tucked in the driver box, which keeps accidental changes from happening after installation. I prefer this “set-and-forget” approach; it cuts callbacks.

The unit is ETL listed and dustproof. There’s no wet-location rating and no emergency battery included. If you need egress lighting or wet-location compliance, plan for separate components.

Installation experience

• Drop ceiling (recessed): This is the panel’s home turf. Pull the old troffer, wire hot/neutral/ground, set CCT/wattage, and drop it into the T-grid. The panel is light enough to manage solo, though I recommend a second set of hands to avoid stressing the lens on lift-in. I also used safety tethers; a good idea for any ceiling panel.

• Suspended: The panel includes provisions for suspension (aircraft cables/kit not included in my shipment). Once level, it looks clean and modern. The lightweight build makes leveling easy.

• Surface mounting: You’ll want a surface-mount frame kit if you’re going onto drywall or directly to joists for a finished look. Without a frame, direct screw-through mounting can work in utility areas, but it’s not as tidy and risks flexing the panel. With the frame kit, the result looks intentionally architectural.

Wiring is straightforward. If you’re using 0–10V dimming, bring the low-voltage pair (typically purple/gray) back to your control. If not, cap them off and the panel runs at full output. Note that 0–10V is not the same as a standard triac wall dimmer—it requires a compatible low-voltage dimmer or control system.

In my installs, I ran a mix of 120V and 277V circuits. The driver handled both cleanly. As always, confirm your site voltage and follow code around low-voltage separation.

Light quality and output

The selectable wattage is the star feature. At the high setting, the panel produces up to around 7,700 lumens; at lower wattages you trade output for energy savings. Across settings, the efficacy is strong for this class—roughly 154–192 lumens per watt based on the stated numbers. In practice:

• 40W: Ideal for corridors, smaller rooms, or areas where you want comfortable ambient levels without glare.
• 50W: A good general-purpose sweet spot for offices and classrooms.
• 60W: Great for shops, high ceilings, or anywhere you need punchy illumination.

Color tuning is simple and meaningful. I used 4000K in offices for a neutral, comfortable feel, 5000K in task-heavy areas, and 6000K in a workshop where contrast matters. Colors render as expected for a commercial panel—no weird shifts or obvious green/magenta tint. If you’re doing color-critical work (design, print proofing), you’ll want fixtures with published high-CRI metrics; for office, retail back-of-house, and utility areas, these panels are more than adequate.

Glare control is solid. The diffuser is well balanced—no visible diodes, no bright edges. Visual comfort in a workstation environment is excellent, particularly at the 40–50W settings.

Dimming and control behavior

With a proper 0–10V control, dimming is smooth and predictable across the range. I didn’t encounter flicker or buzz. The panels start instantly at all dimming levels and recover uniformly, which matters when multiple panels share a control zone.

A practical note: If you’re retrofitting a space that used standard line-voltage wall dimmers, budget time (and wire) to convert to 0–10V. The payoff is worth it—better range, better stability—but it’s extra work compared to a simple lamp swap.

Energy, heat, and noise

These run cool for their output. Even at 60W, the backplate got warm but never hot to the touch, and there’s no fan or mechanical noise. In a quiet office, I heard no electrical hum. Power factor and THD aren’t published here, but subjectively, compatibility with typical commercial circuits was uneventful.

Day-to-day experience

What I noticed most after install was just how finished the spaces felt. Uniform, diffuse light does more than make things bright; it reduces harsh shadows and eliminates the visual clutter of tubes and reflectors. The result is a clean ceiling plane that disappears.

The flexibility to adjust CCT and wattage on-site is a big advantage. I often fine-tune lighting after furniture is in place; being able to “right-size” each room without replacing fixtures reduces waste and makes clients happier.

Durability, QC, and support

Functionally, every panel I installed powered on without drama and has continued to run reliably. The Achilles heel is physical fragility during handling and shipping. These panels are large, light, and have a wide acrylic face—if a carton gets hit on the corner, the lens can crack. My advice:

• Inspect cartons on arrival and open them flat.
• Handle by the frame; avoid pressing on the diffuser.
• Stage panels near install locations to reduce carries.
• If anything arrives damaged, document it immediately and contact support.

On that last point, Sunco’s replacement process was straightforward and quick in my case, which matters when you’re on a schedule. The 7‑year warranty is generous for this price tier and adds confidence for commercial deployments.

Where the Sunco panel makes sense

• Offices, classrooms, and healthcare corridors where uniformity and comfort matter.
• Workshops, garages, and utility areas that benefit from high output and higher CCTs.
• Retrofits replacing 2x4 troffers in grid ceilings with minimal ceiling disruption.
• Mixed-use spaces where you need to commission CCT and output after install.

What could be better

• Packaging protection: A sturdier lens protector or improved corner reinforcement would reduce transit damage.
• Accessories transparency: Surface-mount frames and suspension kits aren’t bundled; make sure you order the right kits for your application.
• Residential dimming: If you’re expecting compatibility with a standard wall dimmer, you’ll be disappointed—these want 0–10V. That’s not a flaw, but it’s a constraint.

Practical tips before you buy

• Count your circuits and dimming zones before choosing pack size.
• Decide on CCT and wattage targets per area; label your settings on each panel’s driver box.
• If you don’t plan to dim, cap the control leads and consider using the 40W or 50W setting to save energy without sacrificing comfort.
• Order one or two extra panels as spares for large projects, or confirm lead times for replacements.

The bottom line

The Sunco 2x4 LED panel is an efficient, quiet, and flexible drop-ceiling workhorse with real-world advantages: selectable wattage, on-site color tuning, smooth 0–10V dimming, and uniform, low-glare output. Installation is refreshingly uncomplicated in grid ceilings, and with the right accessories, it adapts to suspended or surface applications. The build is lightweight, which makes handling easy but underscores the need for careful unpacking and transport. Support and warranty coverage help mitigate that risk.

I recommend this tool. It’s a strong value for commercial and utility lighting where you want high output, commissioning flexibility, and modern controls without overcomplicating the install. If you can accommodate 0–10V control and handle the panels with care, you’ll get reliable, high-quality light and a clean ceiling aesthetic at a very competitive operating cost.
