LED lighting for silhouette projects

Battery Powered LED Strip Light PIR Motion Sensor Bed Wardrobe Cabinet LD1735.
Took ages to arrive from Australia?

Up to now while waiting for this to arrive, I have been using a standard string of LED's powered by a 2 cell battery pack with simple ON-OFF - see last picture.

  

The controller has some nifty features, I figure will nicely enhance my scroll saw night light projects.

This is what I have been using, still a viable option because most of the LED's are not needed (maybe 5 or 6) so the batteries will last for a much longer period.
