a bayonet fitting. Now ES fittings seem to be appearing!

Is there a particular advantage of the ES fitting over the bayonet
fitting in these sorts of applications? |
There is one situation where an ES fitting is clearly superior: Bulbs subject to shocks and vibrations, like in a handheld inspection lamp.
The wobble of the BC fitting added to the shocks and vibrations will reduce the life of the bulb to only a few days, if at all. With ES fitting the bulb is more securely fastened to the lamp and will last much longer.
