  Westinghouse Mini
Pendant Street Light

In the 1940s and 50s there was competition among manufacturers to produce lower intensity street lights for alleys and narrow residential streets where minimum side splash was preferred. These fixtures typically used a maximum bulb size of 200 watts. While some companies like Line Material and Joslyn made smaller luminaires to accommodate their junior sized refractors, others like GE and Westinghouse made adapter rings so that smaller reflectors and refractors would fit to their standard size luminaires.

This particular mini gumball came with a GE Form 110 head. Eventually I located a Westinghouse NEMA head. However the lamp first went back in service with the GE Form 110.

Various components laid out.
"Westinghouse" on the rim.
Top of the head and plug for adapter plate.
Assembled lamp on the test bench.

The optics were subsequently fit to a Westinghouse NEMA head:

Since this lamp was going into service for dusk to dawn area lighting and a 250 watt mercury vapor lamp would be excessive, the internal parts were retrofitted to take a 110 volt CFL lamp.

Back in service to provide outdoor area lighting.
