I have recently gotten into putting together “book nooks”, shelf-size dioramas of small rooms, streets, or other scenes with miniature furnishings and figures. Some of the kits come with light kits, some don’t and one had one of these motion sensors. It is so cool when you walk past a shelf and the little scene lights up. So, I wanted to convert some of mine to motion sensor. I found Evans Designs online and wow! They had exactly what I needed - these sensors, the small lights, battery holders, connectors - and a nice video about lighting a book nook! Kn top of it all, they also made sure my order had everything I needed! In 5 minutes I had 4 lights set up and connected to the battery box, and the on/off switch, and the motion sensor! And it all worked. Yay!! I have to thank the folks at Evans Designs - I’ll be buying more lights soon!!
