The lights are white. I am planning to call the manufacturer to get the spectrum. I think I will put up a T5 white/actinic blue, with LED moon lighting and try adding one of these to see if it does give that shimmering effect. If it works I will post and let everyone know as I have 4 fixtures and will probably only need 1. They come with bare wires and appear to be designed for a electrician to install them to a ceiling or under a shelf so, I will have to buy a cord to attach them to. The seller says they were all wired to a plug cable and just plugged into the wall outlet.
