The PTP EP architectural linear series is an extraordinarily efficient steel luminaires. The PTP EP is designed with direct and indirect distribution for suspended mounting. This series can be mounted individually, in perfectly aligned continuous rows or in any of combination of patterns. This series is available with direct and indirect lamp control and 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, top and bottom of housing have a 3/8" regression for structural rigidity and conformity. 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 for direct lighting element. Indirect is open.
Reflector: Both direct and indirect reflectors are 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. Direct and indirect lamps are dual circuit switching.
Mounting: Standard Installation is an adjustable self-locking aircraft cable assembly 48" x 3/32" in diameter with 5" canopy. One 16/4 SJT straight 54" cord is supplied with each power feed. Standard pendants are available in 24" lengths. See Accessories for additional mounting.
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 two to four 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.
