I'm getting ready to burn in my Ushio and wiring the e-ballast to the mogul and power in. The schematic on the side of the ballast show two sets of wires, Brown & Blue and Brown & Blue. However the ballast itself has one wire with Brown & Blue and one with Blue & Red. Which is the 110V power in side (I'm thinking brown is hot) and which one is the lamp load side?

No guesses please. An answer from someone who knows for sure.

I can't believe there's such a discrepancy on a critical (and potentially dangerous) item!
