Journey towards Making the Most Efficient Garden / Pathway Light

When I first started with Solar Lighting it was to create a simple robust street light.
Created a Light that was good and robust. It was a typical Solar Street Light.
The LEDs were superflux capable of being driven to 50mA - The cooling was provided by the four leads and the PCB was made with lots of copper area to dissipate the little heat.
The design as based around a PIC micro-controller and the output was switching via the controller.
This was in 2005.

Since then I have tried various designs in lighting streets, gardens, porches and pathways.

I am on track to now make one of the most efficient lighting for Gardens, Walkways, pathways and porch lighting.
