Our "light up a room" for "a good few hours" are camping gas
lanterns. One has a piezo ignitor so no looking for matches in the
dark.

It looks like they do a couple of versions but only one with Piezo
ignition.

The self sealing "click" gas canisters avoids the problem of
removing a pierced container type one before it's empty.

I think I have that in the form of a camping stove (or two).

As you say, the good thing(s) about those is the level of light and
being 'always available' (subject to a stock of gas canisters etc).
