Finally taken some pics of my new triple Cree light:
one with the lenses out
...the lens holders had to be cut down slightly to fit 3 in the tin.
and finally showing the separate electronics - still a work in progress
Lenses are Cree 8 degree.
Heatsink is a Zalman ZM-NB32K
Housing is a cut down Schwarzkopf Mess Up Gum tin
Stuck together with Arctic Silver epoxy
Driver is a Taskled Fatman
Separate electronics on stripboard is a LM2951 and a PIC12f683, running pushbutton level control and low voltage flash / auto shutdown for 1 or 2 cell LiIon batteries.
The plan is to use this as a helmet / head light initially. I'll be building up a quad with higher bin LEDs when those become available to take over those duties, at which point it will become a bike mounted light (I'll also put in a buck driver to use with 4 cell LiIon batteries for that).
