All my lamps are rated 60w/240v and my supply today is 243v.
I've never seen a nominal 250v mains supply in the UK.

All your lamps will be *marked* 240v which bears no relationship to
what they (and I use the term very loosely) are engineered for.

In the good old days before Brussels stuck their nose in you had 240v
lamps that, on a 240v +/- 6% supply would last their prescribed
hours. Now you get "240v" lamps that are anything but.
