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.
