Thanks everyone. I can't put a dimmer on the lamp as its a touch lamp (but only one light setting) and they don't work (I actually have 2 Ikea ones to take back as I tried them). The lowest normal sized globes I could find is a 14w, the 7w ones are a smaller globe and I'm not sure if they are ok to use. It's a small Edison type globe and I can't find a blue globe for them. She had an older lamp that did have a blue globe (it was a larger screw type globe) in it but Father Christmas gave her a new pretty lamp and she doesn't want to part with it now.
