"'Er indoors" wants this up on the patio over the festive season...

I've disconnected the control gear from that Thorn Gamma 6 and used it's part-night photocell* to operate this monstrosity.
The blinking red LED visible on the photocell is just it complaining because I disconnected it. It takes a few dusk-dawn cycles to sort itself out.

*Got a load of 3-phase cable for free and I used it to wire the outside stuff so I had the possibility of doing stuff like that.
