There seem to be lots of these little stick on LED lights around.

Something like that would be ideal for lighting our small under stairs
cupboard used for storing the kitchen crockery.

But I ones that I have turn on would just annoy. I'm looking for some
that have a built in light/dawn-dusk sensor so will turn themselves on.

I can't find any, anyone know if such a thing exists yet?

Yes, i know I could fit a sensor and wire in a light etc, but that
require rather too much in the way of roundtuits at the moment

If when it is dark, then it will be on all the time the door is closed (unless
it sees its own light in which case it switches off and then it gets dark agin
so...)
If it turns on when you open the door and let some light in then it will see its
own light and stay on...
You can buy them with a door switch (magnet) built in I think.

My mum just bought one with a PIR or some similar sort of sensor, tiny
little thing that she's put over the front door. It works very well, if
interested I can ask if she still has the packaging or instructions...

I don't quite see how this would work, a dawn to dusk sensor inside a
dark cupboard?

Not a good power-saving measure :-) I assume the OP means to have a
separate switch to control on/off, and the sensor dictates the level of
supplemental lighting.

Oh, against my better judgement, I bought some cheap little stick-on
closet lights the other day (incandescents though, running off a couple of
AA's each). They're utterly crap and provide no useful light whatsoever -
far less than what naturally illuminates the cupboard space via the open
doors if the room light's turned on (which isn't much, but still better
than these things).

Needless to say, I'll have to just do things properly and hard-wire some
proper lights and a switch in there...

cheers

No, just invert the logic of the dawn to dusk sensor light comes on when
it's light enough. Can't help thinking that the power required to have the
sensor circuit running all the time will mean the batteries are flat when
ever you open the cupboard...

Get a bit of bell wire, an arm operated micro switch and a couple of
screws to fix the switch. Microswitch is held off with the door closed.
Place the microswitch in series with the units switch, you can then have
manual control whilst in there or wanting to leave the door open for a
while but it's impossible to leave on with the door shut and can be
automatic.

Choosen 'cause it had a picture. You could go posh and have a roller on
the end of the lever.

Done this with mains lighting in a loft (switches off when hatch shut) and
in a pantry (switches on with open door).

I bought some in Costco last November, in packs of three for about £8.

Used in a dark cupboard, they sense a little light when the door is
opened and switch on. There's also an override.

Indeed, I was talking a load of rubbish of course - whoops, brain fart
:-)

I did mean of course a light sensor that would turn on when it got
exposed to light. alternatively a little PIR sensor would do the job.

Maybe, but for a few quid I'm willing to give it a go.

Yeah I could do this, I did something similar in the pantry in the old
house, but really I want something that doesn't require any roundtuits.

some have mentioned magnetic switches, which might be ok, though at the
moment the door doesn't close properly (it needs planning down, another
roundtuit.

anyway, thanks everybody for the suggestions.

Yes, Costco used to sell some that do exactly this. They have a directional
light sensor that detects when a door is opened. The sensor has two
sensitivity settings and seems to work well. Of course if you're opening
the cupboard in the absense of any significant light outside the cupboard
they won't turn on but they have a manual override.

I'm afraid ours have no makers name and the packaging is long gone but
hopefully someone will know.

Well, been looking more, still haven't found any with the light sensor,
but, seem to be plenty with PIR, so will probably try those.

Two replies (including mine) have suggested that you look in Costco.
I bought two 3-packs of LED lights with the light sensor at Costco in
November. They work well.

Yup, and thanks, but I don't have a Costco anywhere near me

what you need tehn is a solar cell to recharge the batteries
