SPECIFICATIONS:
• Recessed 2X4 Total Volume Luminaire designed to meet the three most important criteria in lighting; energy ef ciency, comfort and aesthetics.
• Efficiency: Enhanced two-lamp linear T5 or T8 fluorescent light- ing system produces significant energy savings over other types of recessed luminaires. Up to 35% in energy savings over three-lamp 18-cell parabolic fixtures with comparable lighting levels. Low watt per square foot ratios helps to meet most lighting power density codes. Fixture efficiencies exceed 84% as tested with two 54W-HO-T5 lamps. Quali es for many state and national rebate programs.
• Comfort: Engineered and designed to  ll an entire volume of space with near perfect illumination. Evenly  lls that space with comfortable illumination, making it feel more spacious, attractive and inviting. Walls and vertical surfaces are evenly illuminated from top to bottom. Retail spaces come alive, as merchandise looks natural. Workspaces are more attractive and friendly and a sense of well-being is achieved. Class- rooms become more inviting as students have less fatigue and are more apt to learn. Facial features look their best.
• Aesthetics: Attractive luminaire design has subtle curves and transitions quietly from lenses to matte white re ecting surfaces. Blends into the ceiling without drawing undue at- tention.
• Housing: Die formed from 20GA cold rolled steel and fab- ricated in a computer-controlled operation. CAD designed re ector system. Spot-welds and rivets hold all parts together for strength and unity. Pry-out style grid supports are located on the sides.
• Twin light shields: Extruded from 100% acrylic with an add- ed colorless frosting blended into the material. Allows max- imum light transmission for higher  xture ef ciencies while hiding lamp imaging.
