Highmast Pole Lowered for Service
|
This was also taken by my uncle's friend. He was working at a place in Providence on these IIRC. There was a bad ballast in one of the Holophanes that he had to replace. The one bad ballast caused the whole set to go dark. This is my favorite style highmast optical, though i like the older ones with the round paintcan style ballast compartment.
These things are basically modified highbays if you think about it. About the same size, they look similar, the only difference is that highmasts have a slipfitter and are weatherproof. That's his van in the background. E-150 or E-250?

I didn't know Holophane made a LED highmast too, at least theirs looks more like a traditional one. The MTO started trying out these in parts of Ontario and I have to say they look quite odd...
I haven't seen the MTO use the Powerlite highmast though.
