(1) Lamp installation available.
(2) High Efficiency ballasts are CEE Listed.
(3) Step-down autotransformer. Allows hook-up of standard MV ballast to 480v.
(4) Occupancy Sensors should be used with programmed rapid start ballasts for maximum lamp life.
Standard Occupancy Sensor requires neutral wired fixtures (ex. -120v or -277v).
For phase-to-phase voltage applications (240v) advise Customer Service at time of request.
(5) Please specify Emergency Ballast (120-277v only) lumen requirements at time of request.
(6) Standard acrylic prismatic, pattern 12, 0.100” thick. Call for options.
(7) Unless otherwise specified, fixture will include field installed J-box. Supply wires will exit the center of the fixture, not the
access plate. J-box can be installed without entering the fixture.
(8) Allows for separate control of two ballasts through simple “toggling” of a standard wall switch.
Recommend use of programmed rapid start ballast with this control.
(9) 1/4 Turn Fasteners for toolless access to ballast compartment. Does not require lamp removal.
