    Thermal filler

    Can anyone recommend a good thermal filler , as opposed to a paste , to help bridge a gap between a led board mount to casing, some of the pastes seam to thin to stay in place and I'd imagine they would run down eventually. Dont really want to use adhesive.
    Thanks in advance.

    What your asking as actually really unclear. bridge what gap? There shouldn't be a gap really. And if your trying to fill a gap, no paste is going to do it for you. You need something that hardens to some extent to holds its shape.

    We could be of more help if you can give us a clear picture of what your trying to do.

    As it states , between the led mounting board and the casing of the lamp unit. There is a tiny gap. The lamp unit is a yinding clone , Buy 2xCree XM-L2 2500-Lumen With 3 group modes LED Bicycle Light Lamp(Lamp cap only) , from for $44.20 only in Main Website. Worldwide Fast Free Shipping!
    No i haven't used any thing yet as i appreciate a paste wont stay in place an it needs some thing harder, but again as stated was reluctant to use an adhesive.

    Its thermal epoxy or make a copper plate. I try to keep people from buying those because of that reason, just so many rediculous issues with it that other lights just don't have.

    The only 2 decent cheap lights out there you already know. Yinding and BT40. Those 2 are the only remaining lights that aren't total crap anymore.

    It's pretty much pay decent money for lights or deal with cheap junk except the Yinding and BT40 (though they still have quality control issues and lack of warranty, still 100x better lights that those junk Yinding clones)

    Thermal gap pad is what you are looking for, but I can't speak to how it will work with high output LED drivers. It comes in different thicknesses depending on your gap size. Higher W/mK is better.
