| Two OV15 Silverliners, the ultimate mercury-vapor suburban classics. The one on the right has the original flat refractor, while the one on the left has been custom-fitted with a newer square refractor. These lights are capable of light sizes up to 250 watts. Some HPS versions also exist. |

| Two versions of the OV25 Silverliner: The one on the left is the original 1957 design, and the newer 1964 design is on the right. Both are 400-watt mercury vapor. There are lots of HPS-lit OV25s with the 1964 design as well. |

A finned OV50 Silverliner, 700-watt mercury vapor. Later versions of this luminaire (including the Cooper OVL, which was based on the OV50) do not have the fins. |

| Ahh...good times. This pole has the two main rivals in the streetlighting industry, the GE M400A (left) and Westinghouse OV25 Silverliner (right). Both of these luminaires are 400-watt mercury vapor. |
