The Day-Brite / CFI 2FGXG43L840-4-RS-UNV-DIM FluxGrid Gen 2 is a high-performance 2-foot x 4-foot recessed LED troffer designed to provide efficient, comfortable and uniform illumination for commercial, educational, healthcare and institutional environments.
The fixture delivers approximately 4300 lumens while consuming only 31 watts, providing excellent energy efficiency for general commercial illumination. It is an ideal LED solution for replacing traditional fluorescent 2x4 troffers in both new construction and renovation projects.
The 2FGXG43L840-4-RS-UNV-DIM provides a 4000K cool/neutral white color temperature with 80+ CRI, producing clean, crisp illumination that works especially well in offices, classrooms, healthcare facilities, retail stores and other professional environments.
The fixture features a Diffuse Round Smooth (RS) center lens designed to provide broad, comfortable illumination while minimizing direct visibility of the LED light source. The architectural center-basket appearance creates a more attractive ceiling than a traditional flat fluorescent troffer.
The fixture operates on 120-277V universal voltage and includes 0-10V dimming, allowing light output to be adjusted when connected to compatible commercial dimming controls.
Its low-profile housing measures approximately 3-1/8 inches deep, minimizing penetration into the ceiling plenum. This is particularly useful in commercial buildings where ductwork, conduit, plumbing and other equipment can limit available space above the ceiling.
The FluxGrid Gen 2 is designed for convenient long-term serviceability. The LED boards and driver can be accessed from below the ceiling, helping simplify maintenance without requiring removal of the entire fixture.

4300 LUMEN LED OUTPUT
The 2FGXG43L840-4-RS-UNV-DIM delivers approximately 4300 lumens while consuming only 31 watts.
This combination provides efficient commercial illumination while reducing energy consumption compared with traditional fluorescent 2x4 troffers.
The broad light distribution helps provide smooth, even general illumination throughout offices, classrooms and other commercial spaces.
4000K COOL / NEUTRAL WHITE
This model provides a fixed 4000K color temperature.
4000K produces crisp, clean white illumination that is widely used in commercial and institutional environments.
It is particularly well suited for offices, classrooms, medical facilities, retail stores, work areas and other spaces where bright, professional-looking illumination is desired.
ROUND SMOOTH DIFFUSER
The RS designation identifies the fixture's Diffuse Round Smooth center lens.
The rounded diffuser creates an architectural center-basket appearance while helping distribute light broadly and comfortably throughout the space.
The smooth opal-style diffuser helps reduce direct visibility of the LED light source while maintaining efficient light output.
LOW-PROFILE FLUXGRID GEN 2 DESIGN
The FluxGrid Gen 2 features a low-profile housing measuring approximately 3-1/8 inches deep.
This shallow design minimizes penetration into the ceiling plenum, making the fixture particularly useful in commercial buildings where HVAC systems, electrical conduit and other equipment may restrict available ceiling space.
The LED boards and driver are accessible from below the ceiling, helping simplify future maintenance and service.
