Cooper/Crouse-Hinds
Crouse-Hinds is the company best known for its traffic lights, but it's also known as the company that bought out Westinghouse's streetlighting operations.

Their first streetlighting fixture was the L150, made in the early days of HPS.  It was capable of carrying lamp sizes of up to 400 watts.

The L150 was later replaced by the OVM/OVS luminaires.  The OVM carried 200-400 watt lights, and the smaller OVS carried 35-250 watt lamps*.  They were popular in the late 1980s and early 1990s.

Cooper Lighting would acquire Crouse-Hinds in the mid-1990s.

The OV-series fixtures remain a hallmark of Cooper's streetlighting division, just as they were for Westinghouse.  There are eight different OV luminaires available, including the OVL, whose design goes back to the old Westinghouse OV50 Silverliner.  Also, the OVD replaced the OVM, and the OVZ succeeded the OVS.  The OVX is available in a wide range of wattages, from 50 all the way up to 400 watts!

Cooper still makes the OV15, OV25 and OV50 for sale in Canada.  Long live the Silverliners, even though they now reside north of the border!

*Special thanks to David Frangioso for pointing out the lowest wattages for the OVS.  You can find them in 35- and 50-watt varieties in the Boston area.
