• High ef ciency 2X2 recessed  uorescent luminaire featuring a complete menu of available diffusing media, lamping choic- es, and ballast options. Specify the appropriate combinations for the application and desired performance needed.
• Applications: A broad spectrum of uses in all commercial, retail, and public buildings. Use in of ce, school, and medical environments. Small, medium, and large rooms illuminate well with evenly spaced 2X2 modules.
• T5 Lamps: Linear 14W-T5 or 24W-HO-T5; two, three, or four- lamp cross sections.
• T8 Lamps: Linear 17W-T8; two, three, or four-lamp cross sections. U-6”-shaped 32W-T8; two-lamp cross section. U-1-5/8”-shaped 32W-T8; two or three-lamp cross sections.
• TT5 Lamps: Twin-tube compact 40W-TT5, 50W-TT5 or 55W-TT5; two or three-lamp cross sections.
• 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.
• Door frames: Heavy gauge  ush steel frame has mitered-look corners and contains the speci ed 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  nish. Aluminum frame is able to withstand damp locations. Available with a 3/8” regression or  ush style.
• Finish: All steel housing parts  nished with a white enamel paint providing a re ectivity of 87% or greater. Optional white powder coating  nish is applied after fabrication providing a minimum re ectivity of 90%.
• Diffusers and louvers: See ordering data for complete list of available media. Diffusers include both extruded and injec- tion-molded acrylic types with various speci ed lighting pat- terns. Louvers include both plastic and aluminum types with various speci ed cell sizes and con gurations.
• Optional optical re ectors: CAD designed to the corresponding lamping and fabricated from Miro-4 enhanced specular alumi- num. Has a 95% re ectivity. (See Series 34-MRT).

• Ballasts T8: Electronic instant start, high power factor, THD less that 10%. Low ballast factor (.78bf), normal ballast factor (.88bf), or high ballast factor (1.20bf) as specified. Up to 4-lamps per ballast is standard. Optional T8 ballasts: programmed rapid start, step dimming.
• Ballasts TT5: Electronic instant start, normal light output, high power factor, THD less that 10%. Up to 3-lamps per TT5 ballast is standard. Optional TT5 performances: rapid start circuit.
• Dimming: Lutron or Advance dimming ballasts as speci ed.
• Voltage: Multi-volt operating a range of 120V-277V, 50HZ-60HZ is standard.
• Optional wiring: A multiple lamp ballast operating the maximum number of lamps is standard. For split circuits and switching specify two-ballast option.
• Emergency battery backup: Integrated pack ranges from 450-lumen output up to 1400 lumens. Varies with lamp type.
• Installations NEMA Type G ceilings: For recessed installation into lay-in acoustical grid ceiling systems, 1” grid or 9/16”  ne- line grid. (Nomenclature “E”, ie; 34E). Four pullout type grid clips are located in the housing ends 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 struc- ture as required by code.
• InstallationsNEMATypeFceilings:Forrecessedinstallationinto sheet rock ceilings add additional  ange kit to “E” type luminaire. Optional overlapping  ange trim type (Nomenclature “C”, ie; 34C) is suitable for both sheet rock ceilings as well as concealed spline ceilings. Includes four swing-out leveling lugs adjustable from below  xture.
• Electrical connections: 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.
• 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.
