The McLux was originally a limited-run light made by a bunch of enterprising CPF'ers.
For the history see
New Flashlight as a result of new friends....,
The McLux has landed!, and possibly the first sale thread
McLux TK Sale: (CLOSED).
Some of those original limited units occasionally show up in B/S/T. Unfortunately for you, you just missed a couple.
Now the parts are available for sale at
Dat2zip's Sandwich Shoppe in the
McLux Build Your Own Flashlight section. You will need some decent soldering skills to manage this, not to mention a soldering iron. /ubbthreads/images/graemlins/smile.gif
Occasionally, some models made by various individuals show up in B/S/T. These units can be differentiated from the original run by the lack of the TK designation. Some members without the necessary skills and equipment have successfully recruited others to build one for them. Needless to say, there was a fee involved. Since I haven't gone this route, I am afraid I cannot be of more assistance.
