UK spec is now 230V. Fiddled to make it near as damnit the same as
before by sliding the tolerances around. We're at 245V here which is
still in range.

But incandescents are still 240 volt in UK, and other voltages as appropriate
in other harmonised countries.

253 is still the upper limit, I goove.

For incan bulbs, it actually matters.
Life is proportional to 1/V^16. (240/230)^16 = about half life, running
a 230V designed bulb on 240.
