Sport floodlights feature the new
compact GE Accuwatt
TM
ballast system in which the ballast is
direct mounted to the aluminum housing with a thermal wedge
for optimum heat transfer.
GE Accuwatt
TM
2000, 1500 and 1000 watt auto-regulator circuits
are designed to start and stabilize their respective double-ended
metal halide lamps at their design center.
Ballast dielectric material is rated for a 200 degree C maximum
operating temperature.
Every ballast undergoes a 2500 volt RMS “High Pot” and a
10KV “til” test in accordance with ANSI C82.4, C82.6 and C92.1
specifications. The ballast circuits are also designed to sustain a
nominal lamp over a line voltage dip of 50% for up to four
seconds when operating at nominal line voltage according to
ANSI specification C82.6.

Bi-Level Controls—
The choice of
high/low two-level lighting is also available. System 2 Bi-Level
controls utilize a 15 volt AC signal that is hard wired to the
floodlight to switch capacitance and change wattage.
The 2000/1500 watt and 1500/1000 watt system choices are
available for separate game time and practice light levels.
The ballast circuit will reliably start and stabilize a
nominal lamp in ambient temperatures down to -29
degrees C. The unit is rated for operation in up to
40 degree C ambient temperatures.*
Ballast Maintenance
—
Electrical access is
achieved from the rear of the fixture without any
adjustment to the aiming required. The rear
housing cover is held in place by four captive
corrosion-resistant cad-polymer coated screws.
Optional Instant Hot Restart—

Sport floodlight can be ordered with a new
optional instant hot restart feature. After a
momentary power interruption or line voltage dip
which causes the lamp to extinguish, a 34KV hot
restart circuit will restart the lamp within two
seconds of re-application of power.
