Two of Westinghouse's well-known remote-ballast fixtures, the OV10 (left) and OV20 (right).
Two of Westinghouse's rarest fixtures, the OV35 (above) and AK109 (right).
An MO8, the open-mercury fixture that reminds you of a flat-bottom Silverliner.
An OV12 Silverliner (250-watt mercury) that predates the far more common OV15.
The original OV15 Silverliner (1965 design) is shown above.  At right, two versions of the OV25.  The Silverliner cobrahead (with the new 1964 design) is at the top of the picture, and the remote-ballasted version is at the bottom.
OV15: 175-watt mercury
OV25: 400-watt mercury (Silverliner)/250-watt mercury (remote-ballasted)
The flat-bottom OV15 (above) and OV25 Silverliners (left), circa late 1970s-early 1980s.
OV15: 150-watt HPS
OV25: 400-watt HPS
The OV50 was the largest member of the Silverliner family.  It is currently available as the Cooper OVL.
