They glow in different colors from reds to blues to yellows and so on.
they're quite small but it's okay since they shine and provide moody lighting around the room of choice. You can also change the battery (13w) on the bottom when the one provided runs out.
the only minus is that they have a bit cheap plastic bottoms to them that are fragile.
as long as they're handled with care, they will provide shine for everyone.
I'm thinking of getting more of these soon. maybe for my sister's daughters :)
