Lamp Select Feature
The Ballasts have a
4ft/2ft
switch. Set the selector switch to
4ft
for 4ft lamps and
2ft
for 2ft lamps.
When operating 4ft lamps in high ambient temperature or where the units are rigged
into place with restricted airflow, the
2ft
setting can be used to lower the color tempera-
ture and remove any green spike. The light drops about a half an f-stop in exposure
when dropping from
4ft
to
2ft
.
It is not recommended to operate 2ft lamps in the
4ft
setting. At the
4ft
setting, the
color temperature of the 2ft lamps will rise dramatically and experience a high green
spike.
Extension Cable
To insert the cable, position the logo up to align the key ways
on the extension cable with the circular receptacle on the
ballast. Rotate the locking ring until it clicks into the lock
position.
Lamps can operate as far as 75 feet from the ballast.
(3 x 25ft extensions)
A
Splitter
can be used at the Ballast or on the end of an
Extension Cable to split a 4Bank run into either four Singles or
two Doubles. This allows for greater rigging flexibility.

The Ballast operates remote from the fixture. Connect the Extension cable to the
Ballast and the Lamp Harness. After the lamps are properly installed, the Ballast can
be turned on. Each switch controls one lamp. The color bands on the lamp harness
correspond to the switches as illustrated.
