Sylvania Powerlite R47 and B2255 Streetlights
|
Here's two Sylvania Powerlite streetlights that gailgrove saved for me at a local intersection.
Ballast of the B2255, it originally came with a 250w 120v only CWA ballast but I replaced it with this 250w Advance MV/MH ballast since the HPS ballast had a damaged lead and I wanted a MV/MH light.
Likewise, the R47 also had a 250w HPS 120/240v CWI ballast. It was also initially replaced with a 250w Advance MW/MH ballast for the same reason but it later got a 70w MH ballast with the ignitor configurable for 70w MH or 100w MV to save energy and so I could use CMH lamps.
