Another benefit of Bayonet fittings is that the bulb doesn't work itself loose due to vibrations, so it's excellent for use in ceiling fans, trouble-lights, wall sconces etc. Why do you think that cars use bayonet fittings for some of their lightbulbs?

You don't get that flicker flicker and arcing inside the lampholder that eventually destroys the center contact of the socket!

Was sitting in a coffee shop in Chelsea last weekend and watching the bulbs in the oh-so-trendy goose-neck fixture flicker and dim...

Was half-tempted to climb onto the table and re-tighten the little suckers.... [Linked Image]

And any fool can get themselves electrocuted by sticking their finger into a double-contact bayonet socket also....

Why are Edison fittings the world standard? One word...EDISON. Guess he was the Bill Gates of his time.

Regarding the exposed section of screw-base...you remember my story about my mom's co-worker (and amateur electrician) in Germany who got himself killed while on a ladder changing the lightbulb hanging from the ceiling in his room.
