Cheap 'n' nasty Temu lights - but nice case

To be fair, these were very cheap. So I wonder if they were the "off tolerance" ones.
It's not uncommon to see the 2835 LED package driven quite hard in modern LED bulbs, but in this instance it appears to be a very ordinary LED on a standard PCB being driven at unusually high current.

The cases are quite nice though, and do come apart fairly easily. So it could be used as the basis of a project, or even as a stylish and chunky USB plug.

Update:- You can scratch the carbon area to adjust the resistance to something more sensible. The green one now runs at 40mA.

Here's the data:-
Red - 22 ohm and 25 ohm passing 150mA
Green - 15 ohm and 15 ohm passing 218mA
Blue - 15 ohm and 16 ohm passing 208mA
Cold white - 18 ohm and 20 ohm passing 168mA
Warm white - 56 ohm and 75 ohm passing 57mA

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