I'm concerned about how best to remove the glue. It'd be nice (but not necessary) to prevent damaging the original emitter and certainly to prevent damage to anything else.
I'm wondering whether the emitter needs to be insulated from the aluminum substrate. If it does, how best to keep it insulated while insuring good thermal conduction. It'd be nice to be able to remove the new emitter if I decide to replace it. This is likely since the emitter I got is not really from the bin I want and I hope to be able to get a better one down the road.
I'm questioning whether centering the emitter is going to be an issue or if the well in the aluminum substrate is a tight enough fit that it will self-center it properly.
I've found two-part thermal epoxies in the past, but I wonder if there is something out there that this forum's wisdom may be able to suggest that is more optimal for the job. Perhaps something that will make it easier to remove the new one.
Thanks in advance.
I'm very interested to see what this red Cree will do in the Fenix head. I bought a seven LED red AA light from Peak, but I'm very underwhelmed by its output and it's not adjustable (it's too dim for me to care about adjustable anyway). I've been wanting a red led 1XAA light with adjustable output, really good throw (for a AA) and reasonable spill, and there just isn't anything I've found that meets the bill, so it seems dropping a red Cree into a Fenix L1D may be my best approach. I'm quite experienced with building/modifying electronic stuff and have access to very good tools and technicians with better skills than I if necessary.
