Product Overview (for complete specifications, see page 2)
Upgrade Capability: As technology improves, internal LED components may be easily upgraded to take advantage of
the latest systems.
Construction: Extruded aluminum housing is available in one piece up to 24', capable of 16' housing with just two
suspension points. Continuous runs have hairline joints with no light leak. Runs of fixtures can be built to lengths
matching field conditions, including complex patterns.
Electrical: Gammalux products are UL and cUL listed with quick electrical connectors and LED components by major
manufacturers. Multiple dimming options available. Runs of fixtures are tested as a complete system prior to shipping.
Continuous Illumination: LED boards can be oriented to provide consistent illumination.
Optical: Clear acrylic linear prismatic lens reduces harsh shadows and striations on ceiling and adjacent walls.
Finish/Color: High quality paint finish in high gloss or semi-gloss. Custom colors available.

Construction
Housing: Extruded aluminum body 4.00” wide x 4.00” high, 6063T5, 0.070” minimum thickness. Available in one piece, unbroken
lengths up to 24'. Up to 16' housing with just two suspension points. Factory-engineered drawings indicate the location of each board in
continuous runs.
Joiner System: Automatic alignment, no loose parts, one tool to tighten two factory installed bolts for hairline seam. No light leaks.
Fixtures that are built for continuous runs and patterns are assembled into a complete pattern and tested for fit and finish at the factory
prior to being individually packed and shipped.
Mounting: Aircraft cable is 7 x 7 stranded stainless steel with machined stainless steel stopper fitting at the top end (specify C). Lower
end strands are welded and grounded for easy insertion into continuously adjustable cable gripper. Feed cord straight, white 3/C SVT
or SJT #18 AWG. Stems are 3/8” schedule 40 pipe with top swivels (specify S). California UBC compliant stems with internal safety
cables available (specify SEQ). Wall Spacer mounting (specify WSP) allows projection from wall of 3.50” to meet ADA compliant
requirements. Housing can be mounted direct to wall (specify WM). Fixtures can be surface mounted on furniture, cabinets or other
construction for Indirect Illumination (specify SF).
Electrical
Upgrade Capability: Standard fixtures use internal components which allow for simple upgrade to improved compatible LED systems
provided by Gammalux. Restrictions may apply on a case-by-case basis.
Driver: Osram OT50 Optotronic driver, wired for static operation, is default* (specify DVR). Osram OT50 Optotronic driver, wired for
0-10v dimming to 10% output, is default* (specify ZTVL). Dimming by Lutron Hi-Lume A series L3D driver (specify HLAE for Ecosystem
control or HLA3 for 3-wire control). RoSH compliant and UL listed wiring and components throughout. Housing wired with quick-connect
plugs at all mating joints and individually tested. Fixtures that are built for continuous runs and patterns are assembled into a complete
pattern and tested at the factory prior to being individually packed and shipped. All fixtures bear UL & cUL labels. LED components and
specifications subject to change without notice.
* Subject to availability, may be substituted by Gammalux.
LED Boards: OSRAM SYLVANIA or equal constant current. Distributed array, high efficacy, 80 + CRI.
LED System Lifespan: Rated for 60,000 hours at 70% lumen output (L70). Life and output based on maximum ambient temperature of
25 degrees C. 5 year limited warranty on LED components with driver options DVR or ZTVL (3 year warranty with HLA driver options).
Length Option: Runs ordered in Nominal length are built to a length which optimizes for the most continuous LED illumination possible
based on board lengths. Run length is coordinated with installer (specify Length Option N). Runs ordered in Specific length do not
deviate from specified length, LED boards are centered in the run, ends of run may not be fully illuminated (specify Length Option S).
