An interesting new Poundland product. It's a 1 metre section of bright white LED tape with a USB lead on it. There are 30 LEDs along its length, each with its own 47 ohm resistor.
The LEDs are being run at about 30mA which is fairly fierce, but those of a technical inclination could tame it with a series diode to drop in the region of 1V or a couple of 10 ohm resistors to cut the current down to about 100mA. That would make it better suited to applications where it was being run from a USB power bank.
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.
