Well i get cost so its like $35 for the ballast and like $10 for the upgraded ignitor a $.50 switch and $10 junction box, a little know how = priceless
As for them all being the same.... There is only a handful of ballast manufacturers everybody just puts their name on it, hence why i can believe that Vertex and Icecap are the same. But im sure you would never get that on paper.
