Its the screw size, the days of bayonet fitting are numbered.
It's nothing to do with wattage or type of light etc just what it screws into.

The E stands for Edison.
Interesting that the days of bayonet fittings are numbered, what goes around.....

Traditionally, the Edison screw bulb was called ES and has a diameter of 27mm, hence E27. We used to have the 14mm Small Edison screw, SES; the Minature, MES and the Lilliputian, LES
