This is one of Poundland's £5 range, and it actually represents very good value for £5. It's a set of three puck lights with a twist-off battery cover that also doubles as a wall or ceiling mount.
The set comes with an infrared remote control unit with mountable holster and offers four simple functions. Off, dim, on and 30 minute timer.
You can also manually activate the lights by pressing the front to turn them on and off.
Quiescent (standby) current of the receivers is about 250uA (quarter of a milliamp) and I got an erroneous reading of the transmitters standby current. It's much lower then I measured. I'll guess that the high resistance of the meter's microamp range possibly caused circuit instability resulting in continuous processor rebooting.
The units are actually very good.
When I mentioned the internal pull-up resistor function in the microcontroller I meant to say that the current is very low, so it's actually a high value resistance inside.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

just found this, I got 6 of these in me camper van, last year, they do the job, brought loads of aaa rechargeable batts, going to connect it up to a 12v leisure Batt, vie a LM2596 , cut down to 3v, will take batts out first,
It is possible change the 30 timer? Y want change by 5 timer but I do not know how i can do it. I think that the remote control just sent a signal with 1 at the beginning and then 30 minutes another, is that correct?
I got 3 of the cob versions of these lights. I combined the circuits with 3 separate sets of string lights and used 2 x 18650 lithium ions in parallel to power each set (complete with protecting circuitry, of course). It was a fairly successful mod actually, I'm quite pleased with them!
Hiw much a set ? 3 ked remite control lights
Saw the exact same set of lights at a local store here in Singapore (priced at SGD$15). Was thinking of buying them but looking at this video and the comments it’s making me reconsider.
Am personally looking for one with warm white lights and can last at least a week (preferably much longer) on batteries; it’s pointless if they all die within a few days. And it seems like they are using daylight white lights as well, which is too cool for my tastes.
is there a way to make this lamp work with the electricity ???
What kind of Camera did you shoot this with? Excellent Quality !!
An excellent explanation of the circuits shown. As a relatively unskilled electronics hobbyist myself, everything Clive said made perfect sense. I agree about the resistor. I'd use one, personally.
$6.5 usd not bad and the buttons are very good quality in comparison to the buttons on tv remotes that often quit working after a short time as the carbon conductor on them fail
AAA batteries! designed to spend your money.
I have a set but they use AA batteries I use them as night lights, the batteries last for about a month.
I have tried using rechargeables, sometimes they work sometimes they don't do the 3.6 volts of the NiCad's must be on the edge.
I have placed them on the curtain pelmets (nice and stealthy).
What I want is more remotes.
Now I know why poundland sells cheap batteries! Youll need new ones everyday!
I Thought another (wife) was leaving the lights on. No, it eats them
The transmitter could have a switch in series with the supply. As for the lights, they're an effective silent salesman for AAA cells. (I never knowingly buy anything which uses those over-priced and under-powered cells.) And that light looks really feeble.
I buyed today 5 pound from pundland ：）
guessing the controllers have code for both transmit and recieve and pin 4 is being used to select the mode., saves programming 2 different chips
I’m assuming it would be safe to convert these to run off 5v, from my camper’s 12 battery; with a 12v to 5v step down in line?
