CPANL LED Flat Panel | Lithonia Lighting
Our CPANL LED flat panel brings consistent, glare-free light to offices, retail spaces, classrooms, and healthcare facilities. The ultra-thin form factor mounts flush in standard grid ceilings or directly to drywall, creating a clean architectural appearance that blends seamlessly with modern interiors.
The CPANL uses edge-mounted LEDs positioned along the panel perimeter, feeding light into a specially engineered light guide plate that redirects photons toward the room below. This indirect approach eliminates the visible LED dots and shadows that plague direct-array panels.
Mounting options and ceiling compatibility
The CPANL ships with hardware for both suspended grid and direct-mount drywall installations. For drop ceilings, the panel rests in standard 15/16-inch T-bar grids without modification — no special clips or retrofit kits required. Four integrated tabs grip the grid rails and hold the panel securely against vibration or accidental contact.
Direct-mount installations use the included screw flange that attaches to the panel perimeter. You fasten the flange directly to drywall or plaster ceilings, then snap the panel into place and connect the driver leads. The low-profile design keeps the fixture surface within half an inch of the finished ceiling plane.
Energy performance and operating cost
The CPANL delivers 3400 to 4000 lumens depending on panel size, drawing 35 to 42 watts from the AC line. That efficiency translates to more than 95 lumens per watt, cutting energy consumption by sixty percent compared to equivalent T8 fluorescent troffers.
We rate the LED arrays for 50,000 hours to L70, meaning the panel still produces seventy percent of its initial light output after five decades of typical eight-hour workdays. Extending replacement intervals from three years to twenty years eliminates ladder rentals, disposal fees, and the labor cost of changing lamps across an entire facility.

Common questions about the CPANL LED flat panel
The CPANL fits standard 15/16-inch T-bar suspended ceiling grids without modification. We offer 2×2 and 2×4 panel sizes to match common grid layouts. The integrated mounting tabs grip the grid rails securely, and the panel weight remains within the load capacity of typical commercial grid systems.
For direct-mount installations on drywall or plaster ceilings, use the included screw flange that attaches to the panel perimeter. You fasten the flange to the ceiling surface, then snap the panel into place.
Yes, the CPANL dims smoothly from full output down to ten percent using standard 0-10V dimming controls. You connect the purple and gray control wires from your dimmer or occupancy sensor to the corresponding terminals on the integrated driver.
The panel responds instantly to voltage changes with no flicker or delay. We recommend compatible wall dimmers, occupancy sensors, or building automation systems rated for 0-10V LED dimming.
We rate the CPANL for 50,000 hours to L70, meaning the LEDs still produce at least seventy percent of their initial light output after 50,000 hours of operation. At typical commercial usage of eight hours per day, that translates to more than seventeen years before you need to consider replacement.
The integrated driver shares the same rated life as the LED arrays, so you won’t face premature driver failures that require fixture replacement before the LEDs wear out.
The 2×2 CPANL panel delivers approximately 3400 lumens, while the 2×4 version produces around 4000 lumens. Both configurations achieve efficacy above 95 lumens per watt.
These output levels replace typical 3-lamp or 4-lamp T8 fluorescent troffers while consuming forty percent less energy. For detailed photometric data including candela distribution and spacing criteria, request IES files from our technical support team.
No, the CPANL includes an integrated LED driver that mounts remotely in the plenum space or inside a junction box. The driver connects to the panel via a flexible cable harness with a plug-in connector.
You land incoming branch-circuit wires directly on screw terminals inside the driver housing. The integrated design eliminates the need to source, purchase, and install a separate driver component.
The CPANL ships with 4000K neutral white LEDs and a minimum color rendering index of 80. That color temperature provides a balanced white light suitable for offices, retail spaces, classrooms, and healthcare facilities.
The 4000K specification sits between warm incandescent tones and cool daylight, offering versatility for mixed-use commercial environments. The 80 CRI ensures accurate color perception for tasks requiring color discrimination.
Every CPANL ships with a five-year limited warranty covering defects in materials and workmanship. The warranty extends to both the LED light engine and the integrated driver.
If a covered defect occurs, we replace the entire panel rather than requiring field repair. Most warranty claims ship within two business days of approval, minimizing downtime in your facility.
