• Commercial grade high ef ciency surface mounted  uores- cent luminaire. This 2X4 module features a complete menu of available diffusing media, lamping choices, and ballast op- tions. Specify the appropriate combinations for the application and desired performance needed.
• Applications: Use in all commercial, retail, and public build- ings where recessing is not possible or desirable, or when high ceilings necessitate suspending the luminaire down to reasonable heights. Use in of ce, school, and medical envi- ronments. Small, medium, and large rooms illuminate well with evenly spaced 2X4 modules.
• T5 Lamps: Linear 28W-T5 or 54W-HO-T5; two, three, or four-lamp cross sections.
• T8Lamps:Linear32W-T8;two,three,orfour-lampcrosssections. Other T8 lamps on request.
• 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 mitered-look corners and contains the speci ed diffusing media. Hinges down from either side of the housing or may be complete- ly 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.
