Line Materials Night Sentry 175w merc in Riverside, CA

The L-M Night Sentry here is owned and maintained by the city's municipal utility and leased to this private property as a security light in the parking lot. I have not seen one of these in a while. I know there are some Night Sentrys leased by utilities in Nevada though. We have seen it at night and it has a DX white mercury lamp, about half dim but still lights ok, and the wattage would be presumed to be 175w. An added bonus is that it appears this L-M still has its original photocontrol from the 60s. Looks a lot like my Tabet new old stock photocontrol from the mid 60s. Henry aka Dimbulb has one of these beauties in his collection.
