lengths up to 16’.
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 adjustible 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).
Electrical
Ballast: OSRAM SYLVANIA or equal Electronic Rapid Start ballast with less than 10% Total Harmonic Distortion is standard (specify
ERS). Additional ballast options are available. UL listed wiring and components throughout. Housing wired with quick-connect plugs at
all mating joints and individually tested. Max ballast cross section size 1.7” x 1.2”.
Fixtures that are built for individual use or continuous runs and patterns are assembled into a complete pattern and tested with lamps at
the factory prior to being individually packed and shipped. All fixtures bear UL & cUL Dry Location labels. Damp Location labels are
available (specify DL in the options field).
Lamp Stagger (when specified)
Fluorescent lamps are custom-staggered in the lower lamp chamber per exact run length, providing consistent illumination from end to
end in each run. Telescoping modules are not acceptable. Factory-engineered drawings indicate the location of each lamp in continuous runs and the dimensioned detail of lamp stagger. Specify ST lamp configuration.
Optical Performance
Reflectors: Shall be diffused formed high reflectance aluminum.
Dust Cover: Clear acrylic dust cover, snap-in fitting (specify DC).
Acrylic Satin Lens: Shall be 15% DR acrylic (specify ASL).
Acrylic Satin Lens, Medium Diffuse: Shall be 15% DR acrylic (specify ASLMD). Multiply efficiency by .93.
Acrylic Satin Lens, Heavy Diffuse: Shall be 15% DR acrylic (specify ASLHD). Multiply efficiency by .68.
Performance: Independent photometric laboratory testing - ITL or equal - is required. Luminaire is a minimum of 85.8% efficient.
Finish
Housing assembly is electrostatically sprayed with high solids aliphatic two component polyurethane to an average thickness of 2 mils.
over acid etching primer. High gloss or semi-gloss are standard. Specify H for high gloss in Paint Finish field. Specify SG for semigloss. Consult with factory for other finishes.
