I think that PC was actually a bird I've yet to see a PC equipped B2215/B2213 though but I'm thinking it might be rear mounted like on the B2217. Anyways another odd thing I found was the use of MTO truss arms in the parking lot...I wonder why aren't they used anymore.
Yeah, btw the B2217 on the davit pole is controlled with a group relay on another pole. I'm not sure about the dayburning Powerlites in the parking lot though.
I finally saw these at night and apparently the B2217s on the davit poles don't work the B2215 and B2213s in the parking lot do but I think they were a bit dim.
The two lights on the trusses facing the same way as the davit are on in the pic. Does the one with the "photocell" work at night too? perhaps it really is a PC or are you positive it's a gull? shame the davit light doesn't work.
