Hey guys, I picked up a Big Leef about a month ago and I'm trying to get her lit. It came with a Maglite head but the threads are much smaller than a standard D Maglite thread so I'm thinking about swapping on a different head so I have some light engine options. Do you guys have any advice? Does anyone make a different head or light engine for this? I thought the Fivemega heads would work but I'm not 100% sure as there isn't much info available on these lights and the threaded section after the battery tube appears longer than other ones I have seen in pics. Thanks guys!!
