ZKV SERIES
84.2% Efficiency
2X4 Total Volume Luminaire
Enhanced Fluorescent Lighting System
- Recessed 2X4 Total Volume Luminaire designed to meet the three most important criteria in lighting; energy efficiency, comfort and aesthetics.
Specification Information:
Efficiency:
- Enhanced two-lamp linear T5 or T8 fluorescent lighting 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. Qualifies for many state and national rebate programs.
Comfort:
- Engineered and designed to fill an entire volume of space with near perfect illumination. Evenly fills 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. Classrooms 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 reflecting surfaces. Blends into the ceiling without drawing undue attention.
Housing:
- Die formed from 20GA cold rolled steel and fabricated in a computer-controlled operation. CAD designed reflector 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 added colorless frosting blended into the material. Allows maximum light transmission for higher fixture efficiencies while hiding lamp imaging.
Finish:
- A custom formulated non-glare white powder coating is applied to the reflector and the housing after fabrication. Provides a reflectivity of at least 90%.
T5 Lamps:
- Two 4Ft. linear fluorescent lamps; 28W-T5 or 54W-HO-T5.
T8 Lamps:
- Two 4Ft. linear fluorescent lamps; 32W-T8. Others as specified.
Ballasts T5:
- Electronic programmed start, normal light output, high power factor, THD less than 10%. Lutron or Advance dimming ballasts as specified.
Ballasts T8:
- Electronic instant start, normal light output, high power factor, THD less that 10%. Optional T8 performances: rapid start circuit, high light output, or low-watt. Lutron or Advance dimming ballasts as specified.
Voltage:
- Multi-volt operates a range from 120V-277V, 50HZ-60HZ. Dedicated voltages on request.
Emergency battery back up:
- Integrated packs range from 500 up to 1400 lumen output. Varies with lamp type.
Installations:
- Designed for installation into NEMA Type G laying acoustical grid ceiling systems, 1″ grid or 9/16″ fine-line grid. For NEMA Type F dry wall applications an additional flange kit must be used with Type G housing. Four pullout type security clips, located in the housing, lock over the ceiling grid work. Four auxiliary suspension points are also provided for securing to building structure. A quick wiring access plate is located on back of the housing. Additional knockouts provided. Factory installed lamps and power whips as specified.
Listing:
- 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.
