Lamp bases or cap types

23rd May 2015

In the UK we have 4 popular lamp types denoted by their caps, the base bit. The 4 types are.

Bayonet cap, BC or B22

Small Bayonet Cap, SBC or B15

Edison Screw, ES or E27

Small Edison Screw, SES or E14

Just like these

Its looking like the BC range will be fading away in the years to follow in favor or the ES as this one is widely used in Europe and becoming more popular here in the UK. However its going to be a long time I think before these disapear from the shops.
