Wow Harold, was your layout a marijuana growing area in a past life by any chance? That's some pretty serious lighting you've got going on there!
Not meaning to derail (heh) the thread, but could you give a bit of advice on lighting layouts? I must confess to be a bit of a novice to it, I've always concentrated solely on lighting buildings and streetlamps, going for quickfix solutions to all other kinds of lighting. I suppose halogen or incandescant would be the better options, and fluorescent a nono?
