>Yes you need an earth cable to the lamp Just keep the 3A fuse they are different than the glass fuses I have never seen a smaller one fitted to a British 13A plug

Okay - but it wasn't a glass fuse - it was a fuse for a household plug - like this: http://www.diy.com/departments/bq-1a.../177930_BQ.prd

I've seen 2A online, but not on the high street...
