Beginning of 2019 and because such tiny chip controllers they can hardly offer usable light power other than be a decoration gadget, I thought to start experimenting with a 5V controller.

My Circuit this is based on two transistors and a few resistors, the idea is simple.
An comparator circuit this works as a valve (electronic photo diode), when there is incoming sunlight,  LED's goes off, and charging begins.
Then, at sun down, this comparator circuit allows battery energy to flow at the LED's

My new project this is tested (electrical circuit) but now I am looking for finding best solutions regarding final assembly.
Solar panel will be placed at best location, and this IP67 housing will be installed in a location which will be most useful.
Over the spot light housing, I have install a bracket this holding another team of LED, by such a trick this light will be able to target at two directions.

Chinese makers of such gadgets they use low quality housing for such lights, plastics get burned from the sun, and clear acrylics loose their transparency.
I am now optimistic that a real IP67 spot light housing among with true glass, this is a much better solution.
