Form, functionality and tradition: why aren’t lightbulbs flat?

The snap answer is “because no one ever made a flat lightbulb“, but Wired UK now puts the lie to that one: someone displayed a flat lightbulb concept at a design show back in 2008, apparently, though it seems never to have made it to production.

The second (and more considered) answer would probably be “because when they were first being made, limited technology for glass manufacture meant that globular capsules were easier and cheaper to produce, and by the time the technology had improved the shape of a lightbulb was an established given that no one thought to alter“. (I’m not certain about the limitations of early manufacture, but it’s a self-educated guess; anyone who can enlighten me further?)

The paranoid answer might be “their frangibility appeals to the sort of corporate mindset that came up with the concept of planned obsolescence” – in other words, lightbulb makers make lightbulbs that are easy to break because they can then sell more lightbulbs. Pretty sure there’s a logical flaw in there somewhere, though…

But anyway, this tangential waffling is the result of that lightbulb story making me wonder how many other household objects are the shape they are, just because they’ve always been made that way. And from there, it’s a short step to thinking similar thoughts about intellectual and cultural institutions, political theories and so forth…

… yeah, so I’m having one of those Fridays where my mind wanders a lot. Lucky you, eh? 🙂
