Just an addendum to this,
The lights actually came from Vietnam, but were manufactured in China.
The speed controller that came with it was not Double-Insulated neither was it earthed, considering that it had a metal case on it. [Linked Image]
Also, the controller was made to run on 220VAC, which is a bit low for my liking, so the thing is run through a Variac, I just hope that the Variac windings never short!.
The light is run by millions of 5mm grain of wheat incandescent fairy lights in the plastic rods and a cluster of them at the ends of each rod.
Mind you, we all know how long incandescent bulbs last, I wonder how bright it will be in a year or so?. [Linked Image]
