BELOW ARE ALL THE Powerlite STREET LIGHTS IN MY PERSONAL COLLECTION. THE LIGHTS ARE ORGANIZED CHRONOLOGICALLY BY DATE OF MANUFACTURE.
NEMA-Type Fixture - Unknown Date I don't know much about this light. I strongly suspect it to be a Powerlite fixture, since it has the same photocontrol receptacle that my Powerlite R37 had when I got it. There are no labels or markings anywhere on the fixture aside from the photocontroll saying "CANADA" on it, which strongly suggests Powerlite, as they were an Ontario, Canada based company with strong presence throughout the country. Powerlite luminaires were rare in the USA though, so if this is indeed a Powerlite, it is a treat for sure. This was converted to HPS while in use but the ballast burnt up so I junked it. Unsure what what originally in it. Since it's got a mogul socket, I would guess MV and based on the position of the socket, likely 100W. I have converted this light to 100W pulse-start MH.
R37 - 1986 This light is a very special member of my collection, since it is one of my favorite street light models. And being made by Powerlite, a Canadian company, these lights were very rare in the USA. This one was rescued from an abandoned complex in Exeter, Rhode Island. It was originally 150W HPS and had its original lamp and photocell in it when it was removed. This light had been abandoned since the early 90s and when I got it, it was in awful shape. If it wasn't a Powerlite fixture I honestly probably would have left it but I had been wanting a Powerlite (especially an R37) for quite some time. This light was full of all sorts of nests and the steel parts were heavily rusted. The ballast and wiring was toast and the lamp socket bracket was rotted to bits as well. The photocell and refractor were busted. The lamp, a Westinghouse BT25 from 1986, still worked however!
This light got a well-deserved full restoration. I repainted it inside and out including two coats of silver paint and a protective clear coat for a brilliant shine and scratch- and UV-resistance. I bought a 100W MV ballast on eBay for this and replaced the photocell socket (birds chewed the wires), and was able to trace a replacement reflector with socket bracket. I also replaced all the screws and bolts with stainless replacements and tracked down a proper glass refractor for it. This light is now better than new! It's too special to see use outdoors so it will remain permanently indoors with my Tudor and NOS lights.
