Socket/light next to consumer unit

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.
If they forget to look in the right places when crossing the road they could go flat quite quickly.

If they forget to close and lock their doors and windows when they go out, their house could go empty quite quickly.

All sorts of things can go pear shaped if people don't pay proper attention to what they are doing. Whilst I understand that it is both the policy of this site, and the position of many of its members, that not paying attention is perfectly OK, and that under no circumstances must people ever be taught the importance of paying attention, it's not a philosophy with which I have any truck whatsoever.

Then they should learn to FPA is my response to that.

If they forget .... Then they should learn to FPA is my response to that.
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.

I don't like it... its a bodge in my eyes and I'd argue it does not comply with 134.1.1.
We disagree on that.


It would also fail to comply with BS5266 because of the reason John sets out.
And on that too.

But unlike the subjective 134.1.1, I can't wait to see your objective explanation of how BS 5266 applies to a light in a cupboard.


Just fit a switched maintained fitting FGS.
More expensive.

More involved to wire.

And would require a regime of testing to ensure the battery was still working. With a straight emergency light that test (albeit not a 3-hour one) happens every time the light is used.
 
Safety issues? ... With a light in a cupboard? ... What's wrong with you?
What was the reason for wanting a battery-backed-up light? IIRC, the OP did not ask for it.

Kind Regards, John
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.

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').

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.
 
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.

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.
