A few months ago I had mod my working light. I put a WW XM-L T5 into a L1 head. I had seen some of this mods before, so I knew that there will be a gap in the head if you use a XM-L on a board. So I decided to use bare emitter. Here are some pics of the mod
LED glued with Arctic Silver:
I use this head in DD with an E1e body. Due to the low vf it puts 330mA from a fresh CR123.
