GAMMALUX®
Illumination
A The Ambient illumination optic is designed to
bounce light off the top of the wall, back out into
occupied space. The reflector material is white
high refectance, low gloss painted steel. Steel
reflectors are pre-installed in 4’ increments. For
the best effect, use no lamp barrier in the fixture.
AR The Ambient illumination w/Roll-out reflector
optic is designed to bounce light off the top of
the wall, back out into occupied space. The
reflector material is a white high reflectance film
shipped separate from fixtures, in lengths up to
40’. For best effect, use no lamp barrier in the
fixture.
G The Grazing illumination optic is designed to
drive light directly down through the fixture
aperture. The reflector material is high
reflectance,
semi
specular
aluminum.
Aluminum reflectors are pre-installed in 4’
increments. For the best effect, use the lamp
barrier in the fixture.
Lamp Barrier
N No lamp barrier is used. Light will shine
directly onto the top of the wall.
Warning - Lamps wil be visible to viewers in a
a mirror’s reflection or if the fixture is mounted
across the junction of a corridor.
B The lamp Barrier is designed to block direct
view of the lamp from any angle below the
ceiling line. This barrier reflects light upward,
onto the fixture’s main reflector for further
reflection directly down through the fixture’s
aperture. The lamp barrier is hinged for simple
relamping and features tool-less removal for
fixture maintenance. The best use of the lamp
barrier is in conjunction with the Grazing
illumination reflector system.

Lamp Stagger

length and the type of lamp specified, this may result in inconsistent illumination in the run.

STC: Lamps are Custom-staggered throughout the entire run. An ideal range of 3” to 6” lamp
stagger is sought, using 4’ nominal length lamps. In some cases, use of a 3’ or 2’ nominal length
lamp may be required at the end of the run to allow for the most ideal lamp staggering and
producing the most consistent illuminaton throughout the run.

Lamp Stagger (cont’d)
STT: Lamp stagger is pre-set at 4” overlap in all but the last fixture in the run. The last fixture in the
run is a Telescoping module which receives the overlapping lamp from the previous fixture in the
run and also features a sliding lamp. This sliding lamp can be moved to the end of the telescoping
module. Telescoping modules have a 12” range of adjustability.

Run Length
Specify fixtures in nominal run lengths. The level of detail required from the installing contractor is
directly associated with the Lamp Stagger selection:
STC - Housings are built in custom lengths to create a perfect end-to-end installation of
fixtures. However, the as-built field dimensions of the walls may not match the architect’s
designed dimensions exactly. Therefore, factory drawings will be produced showing the
designed nominal run lengths and sent to the installing contractor for written verification or
correction. Manufacturing of fixtures does not start until the final set of approved drawings
(with field dimensions) comes back from the installing contrator.

Run Length (cont’d)
Blank or STT - Exact field dimensions are NOT required. Factory drawings will show the run
of fixtures and telecoping module in such a configuration that the specified (nominal) run
length is located as close as possible to the center of the telescoping fixture’s range of
adjustability. This eliminates the need for accurate field dimensions and allows for some
construction variance in the field.

Wall Interface
PR The Plaster Rail* is a patent-pending invention of Gammalux Systems (USPTO Docket #
54842.8002.US00). This extruded aluminum element allows for the fixtures to be mounted directly
to the wall while eliminating the gaps that are created by putting a perfectly straight housing along
a built wall that is slightly imperfect. Acting in the same fashion as a typical Mud Flange, this straight
rail is added to the wall, and the bottom portion is covered with plaster or other compound which
is then feathered down the wall. This corrects minor inconsistencies in the wall’s straightness and
provides a mechanism for the fixture’s reflector assembly to join directly to the wall. This results in
Total Architectural Integration, a perfectly straight and clean look at the ceiling line.
1) Plaster Rail is affixed to wall at a predetermined location prior to finishing.
2) Plaster or other compound is blended over
the lower portion of the Rail and feathered
down the wall, eliminating minor
inconsistencies in wall straightness.

Wall Interface (cont’d)
3) The wall is textured and finished. leaving a
perfectly straight channel, ready to receive the
fixture’s reflector assembly.
4) The run of fixtures and ceiling are installed.
The fixture’s reflector assembly snaps directly
into the Plaster Rail just above the painted
portion of the wall. Gaps between the fixtures
and wall are eliminated, resulting in
Total Architectural Integration.
AT The Adjustment Trim is a supplemental flange that is affixed directly to the wall. It is flexible so
that it can follow the gradual curvature of a built drywall contruction wall. The Adjustment Trim
eliminates the traditional gap found between most competitor fixtures and the wall.
1) Adjustment Trim is added to the wall at a
pre-determined height.
G A M M A L U X

2) The bottom of the fixture’s reflector
assembly rests on the Ajustment Trim,
providing 1/2” ajustability to allow for minor
variances in wall straightness.

While this Adjustment Trim does accommodate for minor inconsistencies in wall straightness, it can
not correct deep pits. In cases where there is a small gap created between the back of the
Adjustment Trim and the wall, a thin bead of caulking or other compound should be used to fill in
that gap.

Ceiling Interface
GFW Fixtures are provided with a visible flange at the ceiling line. The fixture with this GFW
interface can be installed with either Grid or Drywall ceilings. Fixtures are suspended by wire from
above.
In Grid Ceiling:

GMR fixtures are provided with a mud flange at the ceiling line. The fixture with this GMR
interface is installed with Drywall ceilings only. Fixtures are suspended by threaded rod from
above.
2.13
The drywall material is wedged into the mud flange, secured
with screws, and the mud flange is then covered with
plaster or other compound prior to finishing the ceiling.
In either GFW or GMR trim conditions, the ceiling material itself must be adequately
supported from above and not rest entirely on the flange.
