Sylvania Powerlite B2255

I've had this light for quite a while now but I never did take a newer pic showing the NEMA tag I added to it as well as the reproduction tag showing the revised light source and wattage. The B2255 is rather large and heavy for a 400w light and as you can see a 1kW BT56 lamp will fit comfortably in the large reflector.

A 1kW variant exists and was known as the Sylvania Powerlite B2228. It omits the socket spacer that the B2255 has to accommodate the larger BT-56 lamp. As the B2228 was signifcantly rarer here than the B2255 I debated converting this to 1kW MV but chose not to as the conversion would have required me to drill out the rivets holding the socket spacer to the reflector.

I believe back in the MV days, some of the highways here were fitted with 700w-1kW MV B2228s. The B2255 was more popular here, with the early units being MV and the later ones being HPS. They're still common in some parts of Toronto but in the outer suburbs have been replaced by LED. This particular one was removed during an intersection reconstruction 10 years ago.
