4200 LUMEN LED OUTPUT
The 2FGXG42B835-4-FS-UNV-DIM produces approximately 4200 lumens while consuming only 30 watts.
This provides an excellent balance of light output and energy efficiency for commercial applications and makes the FluxGrid Gen 2 an attractive LED replacement for traditional fluorescent 2x4 troffers.
The fixture's broad distribution helps provide smooth, uniform general illumination throughout the space.
3500K NEUTRAL WHITE
The fixture provides a 3500K neutral-white color temperature.
3500K offers a balanced appearance between warm and cool white light and is commonly specified for commercial interiors where comfortable but clean illumination is desired.
It is particularly well suited for offices, classrooms, healthcare environments, conference rooms and commercial workspaces.
DIFFUSE FLAT SMOOTH LENS
The FS designation identifies the fixture's Diffuse Flat Smooth center lens.
The smooth diffuser helps reduce direct visibility of the LED light source while creating broad, comfortable and evenly distributed illumination.
Its clean architectural appearance allows the fixture to blend easily into standard commercial grid ceilings.
LOW-PROFILE FLUXGRID GEN 2 DESIGN
The FluxGrid Gen 2 features an approximately 3-1/8-inch-deep low-profile housing, minimizing penetration into the ceiling plenum.
This low-profile construction can be especially useful in commercial buildings where HVAC systems, conduit, plumbing and other equipment limit available space above the ceiling.
The diffuser can be removed from below without complicated frames or fasteners, providing convenient access to the internal LED boards and driver.
