Any Warehouse 13 fan is probably aware that the place is illuminated using everlasting Shelby bulbs (S01E09), that apparently never, ever burn out. They may not know, however, that, indeed, Shelby lightbulbs exist and were manufactured in the late 1890s by the Shelby Electric Company. Furthermore, some of them are still working. The best known one is probably the Centennial light, a 4-watts lightbulb that originally hung in 1901 in a hose cart house on L Street and is still operative at at 4550 East Avenue, Livermore California after more than 110 years. Furthermore, it has not been shut off for more than 30 years at all!. These light bulbs follow the original carbon filament Edison style, obviously:
The fact that a lightbulb like this can actually exist brings up to the well known concept of planned obsolescence, meaning that products are designed from the beginning to either become unfashionable or no longer functional after a certain period of time and, hence, buyers are forced to acquire a new one and keep the market running. While this may seem a brand new idea, what with the mobile phone and computer market, in fact it goes back in time to 1932, where it was proposed as a means to end depression by stimulating the market. On the consumers’ pocket, of course.
