    Just in case anyone knows what I'm on about - the Lidl IAN number is;79699.

    Has anyone hacked one of these lights?

    After the second lamp died of intermittent LED, I ordered replacement parts on Ebay - while one of the units was in bits on the bench, I started thinking about a favourite switch mode LED driver. It would be nice to incorporate it in the lamp, but Google can't find the JR611 chip which I assume handles the push button ON/OFF, the low battery warning LED and probably plays some part in current regulator.

    The more info I can get - the less I have to re-invent the wheel.

    Thanks for any help.

    Managed to take a few measurements from a powered up board, but the chip is an SOIC-8, so I'll have to solder single strands on the pins to take measurements from that - the DMM prods are way too fat.
