Thanks guys:
Lava, your right, this was an IBEW (that's "International Brotherhood of Electrical Workers" for you republicans out there) union job. What gave it away? The unistrut frame or the OSHA approved fixtures and eco-friendly watt-saver bulbs.
Terry, this prototype is on a 12 mile long cord (I had to go with 100 gauge wire for the voltage drop) but your idea of the 3500KW inverter would save me having to stop and untangle all the time in the brush.
Mark, good eye on the spare bulb holder. Every time I would replace a bulb, another would blow. So I stoped replacing.
Now as for the cost....Priceless
