Lithonia CLX L48 LED Strip Light
Our CLX L48 LED strip light brings reliable, energy-saving performance to offices, retail spaces, schools, and residential applications where traditional fluorescent fixtures fall short. This low-profile, 4-foot LED strip delivers uniform illumination with minimal energy consumption and decades of maintenance-free operation.
Designed for seamless integration into grid ceilings, surface mounting, or suspended installations, the CLX L48 combines lightweight construction with robust performance. We engineered this fixture to replace outdated strip fluorescents while offering superior color rendering and instant-on functionality without flicker or hum.

- High-efficiency LED arrays deliver up to 4,800 lumens with low wattage consumption
- Rated for 50,000+ hours of L70 operation for long-term reliability
- Dimmable down to 10% with compatible 0-10V controls
- Universal mounting system supports grid ceiling, surface, or suspended installation
Construction & Design Details
The lithonia lighting clx strip uses extruded aluminum housing that dissipates heat efficiently while keeping overall weight minimal for easy installation. Our engineers designed the low-profile form factor to slip into tight spaces where bulkier fixtures won’t fit, making retrofits straightforward even in shallow ceiling plenums.
The injection-molded acrylic lens eliminates visible LED hot spots and spreads light evenly across work surfaces. Unlike exposed LED strips that create glare, the CLX L48’s diffused lens delivers comfortable illumination suitable for office environments, classrooms, and task-intensive spaces.
Energy Performance & Light Output
Luminous Efficacy
The CLX L48 achieves industry-leading lumens-per-watt ratios, typically delivering 120–140 LPW depending on configuration. This efficiency translates to immediate energy savings compared to T8 fluorescent systems, often reducing lighting energy consumption by 50% or more in retrofit applications.
Color Temperature Options
We offer three CCT choices to match your application: 3500K for warm commercial spaces, 4000K for general office and retail use, and 5000K for task-critical environments. Each option maintains a minimum 80 CRI for accurate color rendering, ensuring merchandise, documents, and work materials appear true to color.
Installation Methods & Compatibility
The universal mounting system accommodates three primary installation types without requiring separate hardware kits. For grid ceiling applications, our slide-in brackets engage standard 15/16-inch T-bar systems and lock securely without tools. Surface mounting uses the same brackets rotated 90 degrees, with keyhole slots that accept #8 screws for attachment to wood or metal substrates.
Suspended installations leverage integral cable mounting points at each end of the fixture. We include aircraft cable attachments and adjustable height locks that maintain precise alignment in continuous runs. All mounting hardware ships with each fixture, eliminating last-minute supply runs.

Common Questions About the CLX L48 Strip Light
Select 3500K for spaces where you want a warmer, more inviting atmosphere such as retail showrooms or hospitality areas. Choose 4000K for general office, classroom, and commercial applications where balanced white light supports productivity without feeling clinical. Opt for 5000K in task-critical environments like laboratories, detailed assembly work, or medical facilities where accurate color perception matters most.
Most commercial offices find 4000K provides the ideal balance between comfort and visibility. You can also mix color temperatures within a facility—using 3500K in break rooms and 4000K in work areas, for example.
Specific CLX L48 configurations carry wet location ratings for use in areas exposed to moisture, but not all models include this certification. Check the specification sheet for your exact model number to confirm IP rating and location suitability.
Wet-rated versions feature gasketed housings and sealed electrical compartments that prevent water ingress. These models work well in covered parking structures, exterior building overhangs, and food service areas where washdown occurs. Never install non-rated fixtures in wet locations as this violates electrical code and voids warranty coverage.
The lithonia lighting clx uses quick-connect electrical couplers at each end that allow daisy-chaining without junction boxes. Simply align the connector ends between adjacent fixtures and push together until they click—no wire nuts or electrical tape required.
You can link up to 10 fixtures on a single 20-amp circuit depending on wattage, though we recommend consulting NEC Article 220 and local electrical codes for specific installation requirements. The quick-connect system maintains proper polarity automatically and includes integrated strain relief to prevent accidental disconnection during installation or maintenance.
The CLX L48 requires 0-10V dimming controls—standard residential wall dimmers designed for incandescent or LED bulbs will not function correctly. You’ll need dedicated 0-10V dimmer switches or building automation systems that support this commercial lighting control protocol.
Most commercial lighting control manufacturers like Lutron, Leviton, and Acuity offer compatible 0-10V dimmers. The fixtures dim smoothly from 100% down to 10% output without flicker or color shift. If you’re replacing fluorescent fixtures with electronic dimming ballasts, you’ll likely need to upgrade the dimmer switches as well to ensure compatibility.
Each CLX L48 ships complete with the LED fixture, integrated driver, universal mounting brackets, wire connectors, and installation instructions. No additional components are required for standard installations.
The mounting hardware supports grid ceiling, surface mount, and suspended applications without purchasing separate kits. Wire connectors accept standard building wire gauges, and we include cable hangers for suspended installations. Emergency battery packs, occupancy sensors, and dimming controls are sold separately and should be ordered based on your specific project requirements.
We rate the CLX L48 for 50,000 hours of L70 performance, meaning the LED output will maintain at least 70% of initial lumens for the first 50,000 hours of operation. In a typical commercial setting running 12 hours per day, this equates to approximately 11 years of service.
Residential applications with lower usage will see even longer lifespans—potentially 15-20 years. Unlike fluorescent fixtures that require periodic lamp and ballast replacement, the CLX L48 operates maintenance-free throughout its rated life. The only serviceable component is the driver, which can be field-replaced by a qualified electrician if electrical issues occur, though driver failures are uncommon.
Installation requires basic electrical knowledge and must comply with National Electrical Code and local building codes. If you’re comfortable working with line-voltage wiring (120-277V) and understand proper grounding procedures, the CLX L48’s quick-mount system makes installation straightforward.
However, most jurisdictions require licensed electricians for commercial installations and any work involving building electrical systems. Residential DIY installation may be permitted depending on local codes, but improper installation voids warranty coverage and creates safety hazards. We always recommend consulting a qualified electrician for projects involving multiple fixtures or integration with control systems.
