	Subject - Converting a 208 volt HPS light ballest Jdub Hi everybody. this is my first post here and probably my last. I have a question about these lights that I found for sale. Here's the specs on them: Watts = 400 Hertz = 60 HPF = H Lamp Type = S51 Pri Volts = 208 Pri amps = 2.39 I am wondering if there would be way to re-wire this ballest so that it will work off of 120 volts instead of the 208. The ballest isn't multi-tap. Thanks, Jdub Electricman Nope lctrc789 If no muti tap then no other voltage will work for the ballast it is simple as that sorry.
