Crushing and hacking LED lamps

A very pleasant evening spent crushing and hacking some very similar looking LED lamps from different brands. If you have a go at crushing the plastic, then make extra sure it's not glass, plastic coated glass or hard brittle plastic, to avoid getting cut. Gloves might be a good idea. As these are mains-voltage devices, the usual safety precautions should be taken, including not working on them while they are powered. The live stream channel I mentioned can be found here:-    / @bigclivelive   It's best thought of as a weekly pub meeting for technical people. The hack involves the current sensing resistors. As the LED current flows through them the voltage across them rises up until it reaches a threshold where the circuitry effectively increases its resistance until a current balance is reached. Sometimes there's one resistor, but often there are two in parallel to allow fine tuning of the current. By dismembering one you can make the lamp run at much lower current and temperature. This makes the lamp run more efficiently and it will also last much longer than in its original form. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
