Darren's spot on, these are a generic mover which have been rebaged by various people. As far as I remember they're originally made by Neo Neon.
There do seem to be some slight differences depending whose version you buy (some LED displays are red, some blue).
I bought 4 a while back. They're not the Zoom ones, but almost exactly the same.
Mine have been nothing but trouble, and I wouldn't recommend them. The contacts corroded very quickly in the connections that lead from the transformer to the lamp, which caused them to heat up. They got so hot that they melted the plastic of the screw-terminals, parts of the plastic casing, and in some cases the metal of the contacts as well! I wouldn't be surprised if they actually caught fire if left on for long enough.
Exactly the same thing happened to all four, and I've seen a comment from someone else somewhere on the web saying the same thing happened to his.
Obviously mine might have been from a faulty batch or something so it might not happen to all of them, but certainly worth knowing about!
It's a shame because apart from that they're nice looking units, light, bright, and worked well.
That was my experience, yours might be different...
