Ceiling electrical boxes for fixtures from North America to France

[tinpanalley]

Are ceiling electrical boxes for light fixtures going to be the same whether they're in Canada or France? I essentially have some ceiling light fixtures I'd like to use in France that are from North America and I know the bulbs will need to be 220 and possibly need adapters for the socket but is that all there is to be concerned about?

Ceiling light fixtures need to be supported adequately (depending upon their weight) no matter in which country they are installed.

While appropriately rated Ceiling Boxes are required in North America,
this is not necessarily true in other countries - where the "support" and the electrical "enclosure" may be separate entities.

If "standard" "ES" sockets are involved, while E26 (in North America) and E27 (in Europe) are theoretically different in size (by 1 mm)
in practice this usually does not matter.

Photos of the fixtures may be of assistance.

In my opinion the difference does matter, an ES27 lamp in an ES26 socket will leave much more screw thread exposed than it should. Yes, that should be connected to the neutral but you aren‘t supposed to have permanently bare neutrals either.

French homes these days are required to have DCL sockets for any lights so you‘d have to modify the mounting hardware and fit a DCL plug. Personally I‘d leave the light in Canada.
