Lithonia D2SB48 LED Strip Light
The Lithonia Lighting D2SB48 is a high-performance LED strip fixture engineered for commercial applications, warehouses, retail environments, and residential garages. This 4-foot strip light delivers bright, uniform illumination while consuming significantly less energy than traditional fluorescent fixtures.
We built the D2SB48 with a durable steel housing and impact-resistant diffuser to withstand demanding environments. The integrated LED technology provides instant-on operation with no flicker or warm-up time, making it ideal for spaces requiring immediate full brightness. Whether you're upgrading an existing installation or designing new construction lighting, our D2SB48 offers reliable performance backed by Lithonia Lighting's decades of industry expertise.
- 48-inch (4-foot) LED strip fixture with integrated driver
- Energy-efficient LED technology reduces operating costs by up to 50% versus fluorescent
- Durable steel construction with white enamel finish
- Impact-resistant acrylic diffuser for uniform light distribution
- Surface or suspend mount options with included hardware
Construction & Housing Design
The Lithonia Lighting D2SB48 features a robust steel housing with a white enamel finish that resists corrosion and maintains its appearance in high-traffic commercial environments. The extruded steel body provides structural rigidity while dissipating heat efficiently to maximize LED lifespan.
Our engineers designed the impact-resistant acrylic diffuser to distribute light evenly across workspaces, eliminating harsh shadows and hot spots common with point-source lighting. The diffuser snaps securely into place for easy access to internal components during installation or maintenance. This combination of durable materials ensures the D2SB48 performs reliably in warehouses, manufacturing facilities, retail stockrooms, and climate-controlled storage areas.
LED Technology & Light Output
The D2SB48 utilizes premium LED arrays that deliver consistent 5000K daylight-quality illumination optimized for task visibility and color accuracy. This color temperature closely mimics natural daylight, reducing eye strain during extended work periods and improving visual clarity for detailed tasks.
Unlike fluorescent tubes that degrade rapidly and require frequent replacement, the integrated LEDs in the lithonia lighting d2sb48 maintain 90% of initial light output after 50,000 hours of operation. The solid-state LED technology eliminates filaments and glass tubes vulnerable to breakage, making this fixture ideal for high-vibration environments like machine shops and loading docks.
Installation Options & Mounting
We include all necessary mounting hardware for both surface mount and suspended installation configurations with every D2SB48 fixture. The steel housing features pre-punched knockout holes at standard intervals, allowing electricians to quickly secure the fixture to ceilings, walls, or structural supports.
For surface mounting, the included brackets attach directly to junction boxes or structural members using the provided hardware. The low-profile design positions the fixture just 3.5 inches from the mounting surface, maximizing headroom in spaces with limited ceiling height. For suspended applications, the fixture accepts standard chain or aircraft cable through designated mounting points.

D2SB48 Installation & Performance Questions
The D2SB48 produces approximately 3,200 lumens, delivering bright, uniform illumination suitable for commercial workspaces, warehouses, and residential garages. This output level provides excellent visibility for task-oriented activities while consuming only 32 watts of power.
Lumen maintenance remains above 90% at 50,000 hours, ensuring consistent performance throughout the fixture's rated lifespan.
The D2SB48 carries a wet location rating, making it suitable for covered outdoor installations such as breezeways, parking garages, loading docks, and building overhangs where the fixture is protected from direct weather exposure. It is not rated for fully exposed outdoor mounting where rain or snow would directly contact the fixture.
For uncovered outdoor applications, we recommend our dedicated exterior-rated fixtures designed specifically for weather exposure.
The standard D2SB48 model features non-dimmable integrated LED drivers designed for full-output operation. This configuration optimizes energy efficiency and reduces component complexity for commercial applications where constant illumination is required.
For installations requiring dimming capability, Lithonia offers alternative models with 0-10V dimming drivers. Contact our technical support team to identify the appropriate dimmable fixture for your specific application.
We back the D2SB48 with a five-year limited warranty covering defects in materials and workmanship under normal use conditions. This warranty reflects our confidence in the fixture's construction quality and LED component reliability.
Warranty claims are processed through our customer service team and typically involve fixture replacement rather than on-site repair. Complete warranty terms and registration information are included with each fixture.
The D2SB48 consumes approximately 50% less energy than equivalent 4-lamp T8 fluorescent fixtures while providing comparable or superior light output. LED technology eliminates the ballast, starter, and tube replacement costs associated with fluorescent systems, reducing total cost of ownership significantly.
Additional advantages include instant-on operation with no warm-up period, zero flicker, better color rendering, and a 50,000+ hour lifespan versus 20,000 hours for premium fluorescent tubes.
Yes, the D2SB48 can be mounted in continuous runs with minimal spacing between fixtures to create uniform illumination across large areas. Each fixture requires individual electrical connection to building power, as the integrated driver design does not support daisy-chain wiring.
Lithonia offers optional mounting accessories and trim kits to achieve seamless appearance when installing multiple fixtures end-to-end. These accessories are sold separately and simplify alignment during installation.
Installation requires standard electrical tools including wire strippers, screwdrivers, drill with appropriate bits for mounting hardware, and voltage tester for verifying power shutdown. A ladder or lift provides safe access to ceiling-mounted installation locations.
All mounting hardware and electrical connectors are included with the fixture. Installation should be performed by a qualified electrician in accordance with local electrical codes and NEC requirements.
