I've had one of these for several years now, and it absolutely rocks. I bought it in the USA, so no problem with the wiring, although the transformer is the size of a freaking brick. I have it on the floor pointed at the ceiling, and it fills the space nicely. I have the red/yellow, red/blue, and green/purple color wheels, and they all look amazing. It's the closest thing I've found to the old Joshua Light Show from back in the day at the old Fillmore concerts. So far, no problems with it at all - highly recommended!
Thanks, Rob. You have the Mathmos Space Projector, I'm guessing?
Yep - that's the one.
Sweet, thanks! How long can you run it?
I run it for 6-8 hours at a time, and an average of 1-2 times a week, and the oil wheels still look great.
