    Heat transfer compound

    I've just disassembled a chinese light to fix a short on the cable and found the case was full of some sort of heat transfer compound. It came out in the shape of the internal case (a solid block) but crumbled on touch and was not sticky. Once I've fixed the short I'd like to refill the case with a similar compound.
    Can anyone point me in the right direction?
    As the only stuff I've come across is the CPU paste which I doubt its the same (dries into more of a solid)

    fujik is probably the best option, although to be honest I doubt it's needed. If the driver board has a large copper toroid, it's worth supporting that with some hot glue or non-acetic silicone sealant, as they often snap off with vibration. For the rest of it, there should be enough heat transfer to the case from the edge of the driver to keep it cool.

    cheers for the suggestion Matt, do you know if the fujik sets (and is easily removed) or remains a paste? I'd prefer to fill the case, for piece of mind

    er, I don't actually know - this is more like 3rd hand info from the flashlight crowd. If you ask the same Q on the DIY section of budgetlightforum.com you're guaranteed a more knowledgeable answer (which admittedly, isn't hard )!
