I got these for my fountain in blue. They are beautiful and make the water so blue and sparkly. Then I thought Red would be really great for Halloween with the red water.... goolish. So I am getting another set in red. They can also be used when setting a special table at each plate. No water needed.
Awesome for any accent lighting.... we dropped into our halloween signature drink dispenser, our front pond, and accent lighting all over the house.... so cool! They are a bit pricy, but they last a really long time, and you can change the battery. Well worth it!
