Dangerous Mains Powered LED Strip

A mains powered (240V) strip of LEDs, contained inside a plastic flexible tube. The ends are attached with adhesive tape.

The LEDs do light up, although are inconsistent in brightness along the strip and several are much dimmer than the others.

The power module is just a bridge rectifier, there is no isolation at all, and the whole strip of LEDs and resistors appears to be wired in series with the rectified 240V AC connected across the ends.

The end caps pull off easily to expose conductive parts which will be at or near mains voltage.

The plug is fairly typical of a low cost UK plug, although the fuse inside is an incorrect 13A.
