SPECIFICATIONS
Housing:
6063 T5 extruded aluminum.
Optical system:
Perforated metal, 32" dia. perforation to make up 32%
void, backed with a U.V. stabilized and fire rated diffusing membrane to produce not more
than a 2:1 luminance uniformity across perforations. Reflector material is highly specular
aluminum. Field adjustable optical cavity to allow for two light distributions.
Row ends:
Die formed aluminum endplates, 1/4" min. thickness.
Joints & Intersections:
All joints shall be accomplished using QuickLock joining
systems. Optional intersections in "L", "T", or "X"
configurations shall be die formed aluminum, 1/4" min. thickness, with an adjustment
range of 85 - 275 degrees, c/w wiring cavity.
Mounting:
Brackets attach to existing structure anywhere behind
fixture. Adjustable mounting brackets provide for up to 1/8" wall variance and allow
for vertical fixture leveling.
Electrical:
Power feed can be located anywhere behind fixture through
standard horizontally mounted switch box. All luminaire sections shall be factory
pre-wired to section ends. Optional quick connect plugs available.
Ballast:
Electronic: rapid start, instant start or dimming.
Approvals:
Certified to UL and CSA standards.
Finish:
Thermosetting polyester, electrostatically applied meeting
AAMA 603.8. Available in Ledalite standard white and a full architectural spectrum of
colors. Medium gloss finish as standard.
