  1. Power/ led problems

    Hi all
    I've built a few sabers with no problems, until now ! I've built a Luke
    ROTJ bottom half master replicas, top half custom build, thin neck.
    I tested with a three aaa battery pack, Luke board, 3w green led,
    No problems. I then changed the power to a 4.8 four AA nmh pack
    And after a few minutes the led flickers. When I put the lower power
    Pack in its fine. Is it a led heatsink problem ?
    I'll try and upload pics of my sabers when I work out ...
