These were common throughout the city since the 1920s and a few still may be in service today scattered around Boston. These employed a 120V multiple 860-watt (15,000 lumen) or a 620-watt (10,000 lumen) clear lightbulb specially designed for street lighting service. In their earliest days these lights operated in multiple strings and not street series, During the early 1960s a lot of them were converted to individual photoelectric lighting controls with their bracket right below the base of the globe as you can faintly see here.

The globes originally were glass. In later years plastic ones were used as replacements. Lightweight spun-alunimum "toppers" were used a lot too, as seen. Some of these globes (especially the later UV-resistant plastic globes from the 1980s) were outstanding replications of the originals and did not yellow or fade making it difficult for a well-seasoned vintage street lighting enthusiast (like me lol) hard to tell from the ground if the globe was plastic or glass, albeit only about 12 feet up from my good eyesight ;-)

The fine brick residential buildings from the turn-of-the-century in the background still stand and have been kept in prestine condition.

PS...That's the top of the then-new Prudential Insurance Company building peeking its top level in the background.
