I am wiring a magnetic ballast from Hellolights.com, a small 13 watt magnetic job that came with no instructions. Is polarity an issue on these things? There is of course a white wire and a black one coming out of the socket, with a cord (no ground). The cord has a plain jacket on one side, and a raised stripe on the other, leading me to feel there may be a reason for it...
