If they forget to look in the right places when crossing the road they could go flat quite quickly.One problem with that approach is that if (as seems a common problem with within-cupboard lights, judging by what we hear!), people forget to turn off that light (i.e. turn the supply back on), the battery will go flat quite quickly.

Whether you like it or not, people do forget to do things, so I don't see why you should suggest/promote an idea which could theoretically cause safety issues if they did forget, when there is a perfectly straightforward alternative which does not carry that risk.If they forget ....

We disagree on that.I don't like it... its a bodge in my eyes and I'd argue it does not comply with 134.1.1.
And on that too.It would also fail to comply with BS5266 because of the reason John sets out.
More expensive.Just fit a switched maintained fitting FGS.
What was the reason for wanting a battery-backed-up light? IIRC, the OP did not ask for it.Safety issues? ... With a light in a cupboard? ... What's wrong with you?
That was my fault. Winston said he'd use the upstairs breaker so if the D/S lights tripped, you could see to reset. I said that needs well labelling, and I prefer to use an EM light.....my bad.What was the reason for wanting a battery-backed-up light? IIRC, the OP did not ask for it.Safety issues? ...

Not bad - I presume that both you and winston had arguably 'safety' issues in mind (grovelling around a CU to find the 'reset' in the pitch dark not being guaranteed to always be 'safe').That was my fault.

Quite. Plus it's super convenient when the downstairs OPD operates and the the board area is lit up ready for you to reset it.Not bad - I presume that both you and winston had arguably 'safety' issues in mind (grovelling around a CU to find the 'reset' in the pitch dark not being guaranteed to always be 'safe').
Exactly. I have such arrangements myself.Quite. Plus it's super convenient when the downstairs OPD operates and the the board area is lit up ready for you to reset it.
That's all true, but if one wants a battery backed-up light (something the OP has not suggested or requested) then, as others have said, I would personally favour using a switched maintained light, since that has no downsides other than the one BAS has mentioned of having to periodically check that the battery is still OK.Well, it seems like a reasonable idea to me. As for any arguments about safety issues, whether the battery will run down if somebody forgets and leaves the switch off/light on, I hardly think that matters when we're talking about a simple cupboard light in a house, which doesn't even have to exist at all.
