Here’s a variety of lamp in NYC getting increasingly rarer. Unfortunately I have no info on the brand, but these began appearing on underpasses in the 1970s when yellow sodium lamps began to proliferate. In most cases they replaced incandescent fixtures such as Westinghouse AK-10 “cuplights.” These lamps feature two lengthy filaments that shine in a mellower yellow light than the harsher sodiums.
There are still quite a few of these lurking about, like the ones shown here under the Long Island Rail Road overpass on Cooper Avenue in Glendale, but they will eventually be replaced by white Light Emitting Diode lamps which supposedly last longer and are therefore cheaper.
Check out the ForgottenBook, take a look at the gift shop, and as always, “comment…as you see fit.”
