USG LIBRETTO GMS CEILING ILLUMINATION
OPPORTUNITIES
The Libretto GMS ceiling system allows for a wide variety of creative illumination
opportunities. Lighting can be integrated from both above and below the Libretto
GMS ceiling system depending upon the application and design intention. This
document is intended to be used as a guide for illustrating the various lighting
opportunities available to the end user.
Lighting for the Libretto GMS can enhance the ceiling itself as a decorative
element and/or add aesthetic appeal to the environment in which it resides.
USG can provide a fire rated fiberglass material to cover the perforations. The
material softens and diffuses any light from above it.
Backlit illumination of the ceiling can be achieved by various means depending
upon how the Libretto GMS will be hung in its environment and design intent of
the space. The Libretto GMS ceiling is versatile enough to produce an almost
infinite range of illumination possibilities; from bright, even illumination to softer
and more dramatic effects. Lighting systems can be controlled via a dimming
system to provide a greater range of “scenes”. The use of colored film or “gels”
provides static color background to the Libretto GMS system. Programmable
color changing fixtures can also be incorporated to deliver a much more
theatrical effect that can be tailored to coincide with seasons, holidays or special
events.

The use of linear fluorescent fixtures can provide an effective and
even illumination of backlighting on the ceiling itself and/or creating
an indirect source of lighting above.

For Libretto GMS ceilings suspended at greater distances from the
primary ceiling directional sources can be used. The directional
sources can be mounted on the primary ceiling to illuminate the
Libretto GMS ceiling helping to maintain a clean appearance.

Task lighting can be added below the ceiling to accent objects such
as artwork, corporate logos, seating areas, or reception counters.
By utilizing the systems’ perforations unique patterns or text can be
projected onto the floor or walls by utilizing a directional light source
above the ceiling.

Decorative elements can be added below the ceiling to enhance
the under surface or to help define the space in which the Libretto
GMS ceiling is hung.

Programmable color fixtures can be incorporated to expand the
design possibilities further. The fixtures can create a general wash
or be used to compliment the geometry of the Libretto GMS ceiling.

beam metal halide lamps oriented
above the Libretto GMS ceiling are
also on. Sheets of colored film are
placed inside the top ceiling
allowing color to seen through the
perforations from below. This effect
also creates colorful reflections on
the adjacent walls.

halide and halogen directional
sources. The halogen is dimmed.

Programmable, color changing
LED fixtures placed above the
upper ceiling and at the
perimeter of the lower ceiling
create both color on the ceiling
and adjacent walls. Two LED
wash fixtures are used above
the upper ceiling. Six thin
profile LED cove fixtures are
used for the lower ceiling.
Programming allows for the
LED fixtures to produce either
the same color, or have
differing appearances. The two
low voltage directional sources
are also on, resulting in white
pattern on the walls through
the color and shadow.

Additional Installation Photos - Linear Fluorescent Strips
•

Fixtures used were two-lamp, side mounted T5 fluorescent units. The 24”
length fixture utilized (2) 14watt T5 lamps.
The fixtures were placed roughly 2” apart.
Using the side mounted lamps oriented parallel with the curve helped to
provide for even illumination and elimination of “hot spots.”

Low Voltage Incandescent Asymmetrical Wash Fixtures
•
•
•
•

•
Three fixtures were located on a suspended rail about 24” above the
ceiling and roughly 8” in from the larger outside radius.
The flexible track can be shaped to match the ceiling panel configuration.
The fixtures were space approximately 24” apart.
Each fixture utilized (2) 35watt lamps.
The use of the low wattage incandescent wash fixtures was to provide a
directional source from one side. Using this mounting location we are able
to create additional possibilities for the designer by projecting light through
the perforated openings not covered. Patterns, images, logos or effects
can be projected on the floors and walls below the ceiling.
An additional benefit for the end user is the ability to dim the fixtures
further expanding design considerations.
Provides for a more dramatic and softer glow through the perforations
than the more even coverage of the fluorescent option.

Perimeter Mounted Programmable Color Linear LED Fixtures
•

•
Three linear LED fixtures were located at the inside edge of the small
radius side of the ceiling. One fixture per panel.
The fixtures are 12” in length and about 1” in diameter.
Provides the opportunity for programmable color to radiate from the inside
edge outward for enhanced effect.
Can be balanced with decorative and direction fixtures suspended below
the ceiling at the opposite end.

Center Mounted Programmable Color LED Fixture
•
•
•
One LED fixture was centrally located over the ceiling to provide a more
even distribution of programmable color light.
The fixture is about the size of a small shoe box cover. It is approximately
5” by 12” with a depth of an inch for the luminaire itself.
Allows for color to be added above without the need for any film material.

Decorative and Directional Luminaires
•
•
•
•
•
A thin, flexible low voltage rail can be suspended through the perforated
openings. Thin insulated low voltage cable and aircraft cable easily pass
through punched openings in the ceiling panel.
Lighting system is hung independent of the ceiling.
The flexible track can be shaped to match the ceiling panel configuration.
A decorative element can be utilized to create reflection and interest on
the underside of the ceiling.
A directional source can be added to highlight an object, art work, or work
surface below. This may be important when large expanses of the ceiling
need to have an opportunity to provide light below it.
IMAGE 13b
Many options of
luminaries are available
for the designer.
Additional reflections on
the ceiling add visual
interest in an otherwise
surface in silhouette.
