• Commercial grade high ef ciency surface mounted  uorescent luminaire. This 2X2 module features a complete menu of available diffusing media, lamping choices, and ballast options. Specify the appropriate combinations for the application and desired performance needed.
• Applications: Use in all commercial, retail, and public buildings where recessing is not possible or desirable, or when high ceilings necessitate suspending the luminaire down to rea- sonable heights. Use in of ce, school, and medical environ- ments. 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.
• TT5 Lamps: Twin-tube compact 40W-TT5, 50W-TT5 or 55W-TT5; two or three-lamp cross sections.
• Housings: Die formed code grade heavy gauge cold rolled steel with mitered ends welded into place for strength and uniformity. Snap-in type wireway cover allows for easy main- tenance.
• Door frames: Heavy gauge  ush steel frame has mi- tered-look corners and contains the speci ed diffusing me- dia. Hinges down from either side of the housing or may be completely removed. Two positive action cam latches hold the frame closed. Optional gasketing and tamper proo ng on request.
• Finish: All steel housing parts are painted after fabrication with a white powder coating to provide a durable and long lasting  nish with a re ectivity of 90% or greater.
