We at BLF do not have our sample yet but I will try and help with what I know.
1. The light wil be manufactured by Zax
2. I do not know about heat transfer but CPFItalia has more info..see the link in the OP
3. Cyberescudo is working on a battery deal
4. Unfortunately XPL Hi emitters have a limited availability as we found with the X6/X5 group buy. Cyberescudo has the available emitters listed in his review that is linked in the OP.
