These are nicely made and work great but they only turn on & off with unplugging and plugging into outlet. These are somewhat 'heavy' looking so stringing across a wall inside a room does not balance as well as we'd hoped but they work great outside for patio or porch lighting.  Still, we hang them across a headboard for indirect and mood lighting and they are fine with a subtle warm glow on each bulb despite being LED. Your guests will not be blinded or annoyed by them. Good buy.
