Thanks for your quick replies!
I just called Commercial Lights back to make sure that I am getting the real thing. Sure enough the quote he gave me was for something else made by Advance??? :x The guy's first reply was that Advance is the only brand that he carries... Then I literally had to beg him to double check the part #
and oops...he gave me the wrong quote. Now I have to wait two weeks and pay a little bit more. To make the long story short; I can get the whole package (ballast and capacitor) for $94.19. I hate disappointments so I will probably drop in and order it in person and show them the spec that I got from Advance Transformers Co.
The person on the phone also mentioned that since I am using the ballast with MH bulb, I won't need a starter. Any comments on that!
