EPANL LED Edge-Lit Panel
Our EPANL LED edge-lit panel brings premium lighting quality to commercial and institutional environments. Designed for 2×2 and 2×4 lay-in grid ceilings, this fixture uses advanced edge-lighting technology to deliver uniform, shadow-free illumination across the entire surface.
We engineered the EPANL for spaces where visual comfort matters—offices, classrooms, healthcare facilities, and retail environments. The slim profile integrates seamlessly into suspended ceilings while the high-efficiency LEDs reduce energy costs by up to 50% compared to traditional fluorescent troffers.
With multiple lumen packages and color temperature options, you can customize the EPANL to match your specific application needs. Our factory-installed driver and plug-and-play design make installation fast and straightforward.
- Available in 2×2 and 2×4 sizes to fit standard grid ceilings
- Edge-lit LED technology provides uniform light distribution without hot spots
- Delivers up to 4,000 lumens with efficacy ratings exceeding 100 lumens per watt
- Choose from 3500K, 4000K, or 5000K color temperatures
- 0-10V dimming capability down to 10% for flexible light control
Edge-Lit Technology & Optical Performance
The Lithonia Lighting EPANL uses edge-mounted LEDs paired with a precision-engineered light guide to distribute illumination evenly across the panel surface. Unlike traditional backlit designs, this configuration eliminates visible point sources and creates a uniform glow that reduces eye strain in workspaces.
Our optical system features a white acrylic diffuser that softens the light while maintaining high transmission efficiency. The result is glare-free performance that meets stringent visual comfort criteria for office and educational applications.
Installation & Ceiling Compatibility
Lay-In Grid Integration
We designed the EPANL for drop-in installation in standard 15/16-inch exposed tee grid ceilings. The fixture rests directly on the grid system—no additional support wiring required for most installations. The low-profile design sits flush with ceiling tiles for a clean, integrated appearance.
The included universal voltage driver (120-277V) works with most commercial electrical systems. Our factory-installed wiring harness terminates in a quick-connect plug that speeds up installation and simplifies future maintenance.
Dimming Controls & Energy Management
Every EPANL panel includes 0-10V dimming capability, allowing integration with building automation systems and daylight harvesting controls. The driver maintains smooth, flicker-free dimming down to 10% output, giving you precise control over light levels and energy consumption.
When paired with occupancy sensors and photo controls, the EPANL can reduce lighting energy use by an additional 30-40% beyond the baseline LED savings. This makes the fixture an excellent choice for LEED projects and facilities pursuing energy efficiency certifications.

Common Questions About the EPANL LED Panel
The EPANL is designed for standard 15/16-inch exposed tee grid ceilings commonly found in commercial buildings. The fixture rests directly on the grid tees without requiring additional support wiring in most applications.
Both 2×2 and 2×4 sizes match standard grid module dimensions. For concealed grid or specialty ceiling systems, consult our technical support team to verify compatibility and determine if mounting accessories are required.
Yes, all EPANL models include 0-10V dimming capability built into the factory-installed driver. You’ll need a compatible 0-10V dimming control or building automation system to adjust light levels.
The panels dim smoothly from 100% down to 10% output without flickering. This works with occupancy sensors, daylight harvesting photo controls, and wall-mounted dimmer switches designed for 0-10V LED fixtures. The dimming range allows significant additional energy savings beyond the baseline LED efficiency.
The EPANL typically reduces energy consumption by 45-55% compared to equivalent fluorescent troffer fixtures. A 2×4 EPANL delivering 4,000 lumens consumes approximately 38 watts, while a comparable four-lamp T8 fluorescent troffer uses 90-100 watts including ballast losses.
Beyond the direct wattage savings, the EPANL’s 50,000-hour rated life means fewer lamp replacements and lower maintenance costs. When combined with dimming controls and occupancy sensors, total lighting energy savings often exceed 60% in retrofit applications.
For most office applications, we recommend 4000K, which provides neutral white light that enhances productivity without feeling too cool or clinical. This color temperature works well with computer screens and provides good color rendering for typical office tasks.
If your space has warm finishes or you want a more residential feel, 3500K offers a softer neutral tone. For healthcare facilities, laboratories, or spaces requiring maximum visual acuity, 5000K delivers crisp daylight quality. All color temperatures maintain CRI above 80 for accurate color representation.
The EPANL is rated for damp locations, making it appropriate for indoor spaces with elevated moisture such as restrooms, locker rooms, and covered walkways. It is not rated for wet locations or direct water exposure.
For outdoor applications, fully enclosed parking garages, or areas subject to direct spray or condensation, we recommend exploring our wet-location rated fixtures specifically engineered for those environments. Our technical team can help identify the appropriate product for your specific installation conditions.
The Lithonia Lighting EPANL includes a five-year limited warranty covering defects in materials and workmanship. This warranty protects against premature LED failure, driver malfunction, and housing defects under normal operating conditions.
The warranty begins from the date of manufacture and is transferable if the building changes ownership. We handle warranty claims through our network of authorized distributors and sales representatives, who can arrange replacement fixtures or components as needed. Detailed warranty terms are included with each fixture and available on our website.
No, the EPANL is designed specifically for lay-in grid ceiling applications and does not retrofit into recessed fluorescent housings. The fixture sits on top of the grid tees like a ceiling tile rather than mounting into a recessed can.
If you’re looking to retrofit existing recessed troffers, we offer dedicated LED retrofit kits designed to work with those housings. For new construction or full ceiling renovations where you’re installing a grid system, the EPANL provides a low-profile alternative to traditional recessed fixtures with easier installation and maintenance access.
