The first flashlight I ever saw and owned that might be considered titanium was a Tekna red LED light that had a titanium sleeve that was host to the coin cells. It had a plastic tail and head as I recall. The first light I incorporated some Ti in was a battery pak to host an Arc AAA head:
The first all Ti light I did and perhaps one of the first all Ti lights was a AAA light that I ended up giving to PK:
I consider these old but not necessarily goodies. I held back from using Ti for quite a while due to concerns about thermal management. In retrospect, those concerns may have been greater than need be although the high powered LED's of the time were certainly much less efficient than today and they did generate a bunch of heat!!
To my knowledge, the first limited production Ti lights were from Mr. Bulk.
In the spirit of Oldies but Goodies and as established by the OP, I take the term to mean old technology such as the Luxeon LED's used in these early lights. :shrug:
