.but I hope to learn a few other things as well.
I replaced a ballast kit in a 150W HPS lamp. It is an antique barn light housing.
I went to supply house and got Advance 71A8912 (HX-HPF). That was the only one they had for s55. I wired it up according to the best of my abilities.
Now, I put 120v to it and it lit. As this was my first time to deal with any HID, I sat back and watched. Here are my observations: First the ballast gets hot, 200F
(90C) hot. Second, amp reading at supplywas 1.5a or so, and this was within specs (I think) However, it was pulling twice the amps between the transformer and lamp, 3.2a.
Again, this was my first HID wiring. I followed the diagram and clearly marked wires, but still there was a doubt in my mind. Specifically the use of 2 "commons" and the capacitor in series on the common side.
So, the most pressing issue is temperature of the ballast. As far as I can tell from asking around is that this is normal. Please enlighten me.
I wish I could post a pic of the wiring diagram.
