After years of use, the 4 lamps in the oven needed replacement. Ibought
some from a local shop which were marked 230v and they lasted just
weeks, got another set from ebay listed as 220 - 240v which each lasted
only a week. all were marked as oven lamps, but I wasn't conviced about
that, due to the glass being very clear, rather than toughened. Very
annoying, because they are not that easy to change.

Latest set have lasted a month and were 2 for a pound from Poundland,
marked 240v on the package and on the lamp base, the glass was also
discoulored suggesting they were toughened. Better yet, they have lasted
a month so far ;-)

Try explaining to numpty sales people that 220v is very different from
the 240v in the UK :'(

We harmonised with the rest of Europe many years ago, so UK voltage is 230V
+10% -6%. Anything sold within the EU for mains voltage use should work on
any voltage within that range.

Except filament lamps, which either under run at 220/230v, or are over
run and last no time at all on 240v.
