Globes-memory aid:

Small globes come in 2V, 6V and 12V sizes. The filament colours of the ones we use are different and the 6V globes are bigger than the others, so I find it easy to tell the difference.
I now have the following poem pinned up near the globes.
GLOBES!
Blue are 2
6 are fat
12 are white
Remember that!
