Incandescent bulbs in RLM fixtures at the Fullerton bus depot

The bus depot in downtown Fullerton has two canopies, each with 8 RLM fixtures. My friend told me about these earlier that they had an interesting filament design. Finally I got to see these in person, and they have been identified as GE 150w 130v PS-25 clear rough service bulbs. All the lights have these same bulbs, some have more hours on them than others. Cool to see incandescents still used in public! At least until the KA bulb police tells the transit agency here to put in LEDs, LOL.
