Measuring Emitter Holder

The bottom grey thing is 3mm perspex that will seal the front of the light. Then Calco lenses, square MCPCB and aluminium holder.

Sat next to it is box section housing which was marked with the area that could be used to connect to the aluminium emitter holder.

Don't know if you can make it out in all the shiny stuff - but there is a small 'V' shape filed in the side of the holder here that the power wire will run through.
