Made the mistake of buying one transformer for each loop of lighting. You can hardwire these, but cannot attach the lights directly to housing electrical wire. Received additional supplies quickly; finished job was well worth the wait. These lights are bright, inconspicuous, and cool to the touch. They do a great job of highlighting the backsplash tile. Worth EVERY PENNY that I paid for them!!! I HIGHLY RECOMMEND THESE LIGHTS!!!

The lights and transformer seem to work great only one problem, the clips to hold them up are very easily broken and the adheasive on the stick strips doesnt hold very well either.
