Fitted the LED to the aluminium holder, fits perfectly! The next one
will be basically the finished unit, which will be slightly bigger to
hold the driver electronics and will also have fins to aid dissipating
the heat. It will also mount the LED better inside without the need for
the M3 bolts i am using in this prototype. Weight is currently 426g.
Had prototype v2 machined up, spotted a few problems and redesigned.
Prototype v3 machined, this is now very
close to the production light, weight is now 490grams with battery and
mount. This design now has integrated electronics and a rotary on/off
Lens holder, LED & Lens
Powered without the lens.

The LED in the back garden, this looks
a little brighter than it really is.
