Umm - I checked your nice desk lamp design and build at your site, Nigel.

One question though:
1) -Isn't the chosen GU 10 lamp at full mains 230 VAC voltage (or is it below 24 V)?
If so: You got yourself a protective earth lead to the lamp's base?
And do you have GFI/ RCD device in your breaker/ fuse box?

A low voltage transformer/ SELV powered, low temp LED could be mounted in just about anything, as in your mill light,
but an all metal, mains powered (with perhaps a hot Halogen?) lamp without a proper and connected* earth lead
could give you a blind date with Darwin when a fault happens.

I'm not sure how code might've changed in the UK since New Years Eve, but I guess you haven't ditched the CE regulations yet?

-Just be safe, OK?

Cheers
Johan
