Solve 250 VDC cranelight lighting by installing MERCURY VAPOR
resistor ballasts. Convert fragile, short life incandescent lighting into
heavy duty long life mercury vapor.
The resistors employed in these ballasts are wire wound on ceramic cores.
The enclosures are heavy gauge steel with the outdoor 400 Watt version in
a NEMA 3 louvered box.
Extend lamp life with this cast
aluminum shock mount. The
lighting fixture floats on a solid
rubber base that absorbs shock
and vibration. A ground connec-
tion is installed between the top
and bottom of the shock mount for
added safety.
