The PTP architectural linear series is an extraordinarily efficient steel luminaires. The PTP DIA is designed for wall mounting. The PTP DIA is an asymmetric indirect distribution while providing a symmetric direct distribution. This series can be mounted individually, in perfectly aligned continuous rows or in any of combination of patterns. This series is available with an almost limitless variety of down light shielding. The PTP series is an ideal solution for open spaces and provides maximum design versatility.
Housing: Die formed 20 gauge cold rolled steel welded construction, bottom of housing has a 3/8" regression for structural rigidity and conformity. A 2 1/2" wide opening on top of housing provides indirect ceiling and wall illumination. Joiner ends are notched below the lamps for ease of installation and continuous baffle appearance. Finished end caps are laser cut 18 gauge cold rolled steel, with no exposed hardware or knockouts. Housing aligners provide precision alignment for continuous rows.
Shielding: Parabolic louver is semi-specular low iridescence aluminum 1 1/2" x 2" O.C. with 24 cells per 4' section.
Reflector: Die formed 20-gauge cold rolled steel minimum 90% reflectivity finished in high gloss baked white enamel.
Electrical: Ballast is electronic, multivoltage 120/277, high power factor, thermally protected class P, sound rated A, with less than 10% total harmonic distortion. The minimum number of ballasts will be used unless otherwise specified.
Mounting: Provided with wall mounting brackets measuring 5" square by 1" deep. Finished in white to match housing.
Finish: Fixture housing and steel components are finished in baked white enamel applied over a five-stage pretreatment process.
Lamps: Fixtures are provided for use with one or two 32 watt T8 lamps or 54 watt T5 HO lamps. (Supplied by Others)
Certification: Luminaires are U. L. Listed, C. S. A. certified and are Union Made in the United States of America. I.B.E.W.
