35-MRT SERIES
High Efficiency 2X4 Lens Troffer
Optical Reflector/95% Reflectivity
Low Profile 3-3/4" Deep
Fixture Type:
Job Information:
SPECIFICATIONS:
• A recessed lens luminaire featuring a computer designed optical
reflector fabricated from Miro-4 enhanced specular aluminum.
This innovative material offers an outstanding 95% reflectivity
with the durability to maintain this reflective quality for as long
as 25 years.
• Optical reflectors: Miro-4 or equal 95% reflective enhanced
specular aluminum. Resists scratching and other field damage
and is easily cleaned. Twenty-five year limited warranty.
Optional AmWhite-90 or equal 90% reflective white aluminum.
Reflectors have a unique four-point pressure fit.
• The reflector design maximizes efficiency by directing emitted
light to leave the fixture with as few as one reflection. Multiple
reflections, which happen in standard type luminaires, absorb
about 13% of the light each time it bounces off its white metal
surface. This white metal surface also lacks this high reflectivity
and will depreciate over time.
• Ballasts T8: Electronic instant start, normal light output,
high power factor, THD less that 10% most ballast/lamp
combinations. Multi-volt operates a range from 120V-277V,
50HZ-60HZ. Optional T8 performances: rapid start circuit, high
light output, or low-watt. Up to 4-lamps per ballast is standard.
Lutron or Advance dimming ballasts as specified.
• Improved efficiency: A two-lamp T8 luminaire can replace an
older three or four-lamp type with comparable light levels
using less input wattage. • Ballasts T5: Electronic programmed start, normal light output,
high power factor, THD less than 10% most ballast/lamp
combinations. Multi-volt operates a range from 120V-277V,
50HZ-60HZ. Up to 2-lamps per 28W ballast, up to 4-lamps per
54W ballast. Lutron or Advance dimming ballasts as specified.
• Applications: A broad spectrum of uses in all commercial,
retail, and public buildings. Use in office, school, and medical
environments. Works well in all lighting retrofit installations.
• Optional wiring: Two ballasts for dual circuitry.
• T5 Lamps: Linear 28W-T5 or 54W-HO-T5; two, three, or fourlamp cross sections.
• Emergency Battery Back Up: Integrated pack ranges from
500-lumen output up to 1400 lumens. Varies with lamp type.
• T8 Lamps: Linear 32W-T8; two, three, or four-lamp cross
sections.
• Installations: Designed for recessed installation into NEMA Type
G lay-in acoustical grid ceiling systems, 1" grid or 9/16" grid. For
sheet rock ceilings, NEMA Type F applications, add additional
flange kit. Sufficient knockouts are provided on the back and
ends for all electrical connections. A quick wiring access plate
is provided. Optional single or dual circuit quick wiring flex. • Housings: Die formed code grade or optional 20GA cold rolled
steel with ample strengthening embossments. End plates
are securely riveted onto the housing. Snap-in type wireway
covers. Socket bars are screwed into housing. All steel housing
parts finished with a baked on white enamel paint applied after
fabrication.
• Door Frames: Heavy gauge flush steel frame has mitered-look
corners and contains the specified diffusing media. Hinges down
from either side of the housing or may be completely removed.
Two positive action cam latches hold the frame closed.
• Optional Door Frames: Extruded aluminum frame has true
mitered corners and offers a more architecturally pleasing
appearance and finish. Aluminum frame is able to withstand
damp locations. Available with a 3/8" regression or flush style. • Four pullout type grid clips are located in the housing to lock
over the grid. Four auxiliary suspension points are also provided
on the housing ends as an alternate method of securing to the
building structure as required by code.
• UL and CUL listed 1598 and bears their label. Suitable for dry
locations or optional damp locations with UL Damp Label. Union
made and labeled.
• Diffusers and Louvers: See ordering data for complete list of
available media. Diffusers include both extruded and injectionmolded acrylic types with various specified lighting patterns.
Louvers include both plastic and aluminum types with various
specified cell sizes and configurations. 20 Audrey Place • Fairfield, NJ 07004 • Tel: 973.244.9444 • Fax: 973.244.9522
