Lithonia FMLWL 48 840 LED Wraparound
Our FMLWL 48 840 LED wraparound fixture brings dependable, high-output illumination to commercial and industrial environments. Designed for 48-inch applications, this wraparound delivers crisp 4000K neutral white light that enhances visibility in warehouses, garages, retail back-of-house areas, and office corridors.
We engineered this fixture with a durable acrylic lens that wraps around the LED array, providing uniform light distribution while protecting the components from dust and impacts. The integrated LED design eliminates lamp replacements, reducing maintenance costs and downtime. Installation is straightforward with our pre-wired junction box and universal mounting brackets that accommodate ceiling or surface mounting configurations.
- 48-inch length ideal for standard ceiling grid spacing and commercial bay applications
- 4000K color temperature provides neutral white light perfect for task areas and general illumination
- Integrated LED array delivers up to 50,000 hours of rated life
- Wraparound acrylic lens ensures even light distribution and protects LED components
- Universal mounting hardware included for ceiling surface or chain-mount installation
Construction & Housing Design
We build the Lithonia FMLWL 48 840 with a heavy-gauge steel housing that stands up to the demands of commercial environments. The white enamel finish resists corrosion and complements standard ceiling finishes, while the rigid frame maintains alignment even after years of service.
The wraparound acrylic lens is impact-resistant and secured with clips that allow quick access to the driver compartment if service is ever needed. Our optical design directs light downward and outward, minimizing ceiling glare while maximizing useful illumination at work surfaces. The sealed housing keeps dust and debris away from the LED board, which is critical for maintaining lumen output in dusty warehouses or automotive service bays.
Installation & Mounting Options
We ship each FMLWL 48 840 with universal mounting brackets that adapt to multiple installation scenarios. For drop ceilings with standard T-bar grids, the fixture can rest directly on the grid with optional safety chains for code compliance. Surface mounting to drywall or concrete ceilings is equally straightforward using the included hardware and the fixture’s integral keyhole slots.
The pre-wired junction box accepts incoming power from either end, and our clear wiring diagrams inside the housing guide electricians through line, neutral, and ground connections. Installation typically takes 15-20 minutes per fixture, and no special tools beyond basic electrical supplies are required.
Light Output & Color Quality
The 4000K color temperature strikes an ideal balance for commercial applications—cooler than the warm tones used in hospitality settings, yet warmer than the clinical 5000K often found in healthcare facilities. This neutral white output enhances color rendering for retail displays, improves visual acuity for detail work, and creates an alert, productive atmosphere in offices and assembly areas.
We calibrate each fixture to deliver consistent lumen output across its rated life, with less than 10% depreciation over 50,000 hours of operation. The wraparound lens diffuses the LED point sources into a continuous band of light, eliminating harsh shadows and creating comfortable ambient illumination. Whether you’re lighting a 10-foot aisle or a 400-square-foot storage room, the FMLWL 48 840 provides the coverage and uniformity modern commercial spaces demand.

Lithonia FMLWL 48 840 Wraparound Questions
The Lithonia FMLWL 48 840 delivers approximately 4,000-4,400 lumens depending on the specific configuration. This output is comparable to a traditional 4-lamp T8 fluorescent wraparound while consuming significantly less energy.
The fixture maintains at least 70% of its initial lumen output (L70) after 50,000 hours of operation, ensuring long-term performance consistency.
Yes, this fixture is damp location rated, which means it can be installed in covered outdoor areas where it's protected from direct water exposure. Suitable locations include covered parking structures, loading docks, building overhangs, and breezeways.
For fully exposed outdoor installations subject to rain and weather, we recommend our wet location rated fixtures designed specifically for those environments.
The LED array and driver are integrated into the fixture design and are not field-replaceable as individual components. However, the entire fixture carries our standard warranty, and the LED technology is rated for 50,000 hours—approximately 11 years of continuous operation or 20+ years at typical commercial usage patterns.
The long-life design eliminates the maintenance burden and cost associated with periodic lamp replacements in fluorescent fixtures.
The lithonia lighting fmlwl 48 840 operates on switched power and is compatible with standard occupancy sensors, photocells, and time-clock controls. For best results, use controls rated for LED loads.
This model is not dimmable. If dimming capability is required for your application, we offer other LED wraparound series with 0-10V dimming drivers that provide smooth control from 100% down to 10% output.
The integrated driver accepts universal input voltage from 120V to 277V, making it compatible with most commercial electrical systems in North America. The fixture automatically adjusts to the supplied voltage without requiring any configuration or switching.
This voltage flexibility simplifies specification and installation, especially in mixed-voltage facilities or renovation projects where existing electrical infrastructure varies.
The 4000K color temperature provides neutral white light that's very similar to standard cool white fluorescent lamps (4100K). It offers excellent color rendering for commercial tasks while appearing crisp and professional.
Unlike fluorescent lamps that shift color and lose intensity over time, LED technology maintains consistent color temperature throughout its rated life. You won't experience the yellowing or color drift common with aging fluorescent tubes.
Each FMLWL 48 840 ships complete with the fixture housing, pre-installed wraparound acrylic lens, integrated LED array and driver, universal mounting brackets, mounting hardware, wire nuts for electrical connections, and installation instructions.
No additional components are required for a standard installation. Simply provide appropriate electrical supply and follow local electrical codes for proper connection and support.
