2FG FluxGrid recessed 2x4
up to 7400 lumens
Application
• 3" deep low profile configuration provides
minimal penetration into the plenum space.
• Acrylic diffuser available in ribbed and smooth
configurations provides even illumination with
comfortable appeal.
• Standard and base configurations available in
multiple lumen packages to suit the needs of
various applications.
• Lambertian distribution creates uniform
horizontal and vertical illuminance on the work
plane and reduces scalloping on
the walls.
• CRI 80 minimum color rendering with balanced
spectrum.
• LEDs coupled with standard dimming provide
prolonged lumen maintenance. Optional integral
sensors contribute further to LED lumen
maintenance.
• Designed for use with standard 15/16" wide
Grid (NEMA "G") T-bars. Drywall or plaster
applications require use with the FMA24 "F"
mounting frame accessory (sold and shipped
separately).
• Continuous row mounting is possible with a 1" gap
between fixtures accommodated
by others.
Enclosure
• Opal acrylic diffuser provides visually
comfortable lumenance without compromise to
luminaire efficacy.
• Diffuser requires no frames or fasteners and can
be easily removed from below without the use
of tools.
Construction/Finish
• Uncomplicated design is 3" deep with minimal
material overlap creating several benefits:
- Less material required
- Less packaging required
- Reduced weight for ease of handling and
transit
- Less energy required for construction and
assembly
- More luminaires can be shipped per truck
to reduce fuel consumption
• Metal side covers are die formed with a conical
shape to enhance light distribution and visual
aesthetic.
• Injection molded lens retainers allow for easy,
tool-free access to the LED boards
and driver from below, and provide positive lens
retention,
• Luminaire finish is matte white polyester powder
coat for high quality, durable finish.
• T-bar grid clips are integral to the body.
• Air return option provides air flow through a
unique lens retainer design. Air passes through
architectural forms in the lens retainers (each
end), and through the end plate of the luminaire.
A cover plate is provided to control air flow
through the luminaire, or make it static as
required.
• Integral controls options include sensor mounted
in one lens retainer.
• EMLED option requires the emergency battery
pack be installed with a top side cover. Access
from above.
• To estimate lumen output in emergency mode,
multiply emergency pack wattage by efficacy,
then by 1.10.
General notes
• All options are factory installed.
• All accessories are field installed.
• Many luminaire components, such as reflectors,
refractors, lenses, sockets, lampholders, and
LEDs are made from various types of plastics
which can be adversely affected by airborne
contaminants. If sulfur based chemicals,
pertroleum based products, cleaning solutions,
or other contaminants are expected in the
intended area of use, consult factory for
compatibility.
Electrical
• Integral sensor options for occupancy sensing
and/or daylight harvesting are available for
additional energy savings with no reduction of
life or increase in installation labor.
• Standard configurations provide up to 120
lumens per watt and are available with 5 lumen
packages and 3000, 3500, 4000, and 5000K
color temperatures.
• Base configurations provide up to 124 lumens
per watt and are available in 4200 lumen flux and
3500K and 4000K color temperatures.
• LED boards are accessible from below by
removal of the lens. Lens removal is tool-free by
compressing the sides and pushing to
one end.
• LED driver is accessible from below by removal
of the lens and integral wireway cover. The
wireway cover is easily removed with a flat head
screwdriver.
• Other driver options including step dimming
(SDIM, 100%/40%), DALI, phase dimming (XDIM),
and Lutron are available.
• 5 year manufacturer's limited warranty.
Visit signify.com/warranties for complete
warranty information.
• TM-21 predicted L70 lumen maintenance up to
70,000 hours.
• cETLus listed to UL and CSA standards, suitable
for damp locations.
• FluxGrid luminaires are DesignLights Consortium
qualified. Please see the DLC QPL list for exact
catalog numbers, www.designlights.org/QPL
